Coatesville Renovations Builder – What Do Major Home Renovations Entail?

What Do Major Home Renovations Entail?

For people wanting to undertake a major home renovation, this might be to upgrade their existing home or because they have bought a run-down or older house that they want to renovate. If you have never renovated a home before, you might be wondering what major home renovations entail. Is it a project that you can handle yourself, or do you need to hire a builder for major renovations? These are some of the things you can expect.

Getting The Plans

First of all, what is your desired outcome from the renovation? For any major home renovation you will need to have some plans drafted to consider how these new spaces could look, how they could change the overall appearance and flow of your home and also to figure out which improvements actually fit within your available budget. A good architect or an experienced draughtsman will sit down with you and discuss your requirements and budget. They will ask a range of questions about your lifestyle, the family members (teenagers will have different needs from young school children for example) and the anticipated use of the areas you are looking to renovate. All of these will have an impact on how they design your renovation project.

Using their experience, they will also have insights or ideas that you may not have considered. They might suggest a different configuration of the layout or a different orientation to capture more natural light and warmth.

They will also have an understanding of the shape and slope of the land that you will be building on.  This will have a significant effect on the costs of the building project also.

Once they have your input, they can then go away and draw up a sketch design and layout for you to then review, giving you the chance to either accept the design or for you to suggest changes. Once you agree on the design, they will then make the final drawings.

Once the plans have been submitted to Council, it is important that you do not make any changes to these since they are critical for Council Consent – see below. A renovations builder can use these to produce an estimate, though any later variations from the design will undoubtedly affect the construction costs, usually upwards, as well as potentially causing delays, so be absolutely sure that the design is what you want before the draughtsman or architect makes the final drawings.

Council Consent

It is essential to get approval for your building project from the local Council before you begin any major renovations. This might be Resource or Planning Consent, or both. Getting the Auckland Council Consent is a complex process and people are advised to seek professional help with the process. We can point you in the right direction here if you need help with your application.

As part of the consent process you will need to supply the drawings of the final design produced by a qualified architect or draughtsman to accompany your application. Any major variations from the design might need to go back for further approval – causing delays in your project.

Getting consent is vital as the Council has a range of powers to slow or halt building if the consent is not granted. Often renovation building companies will not quote a project without Council Consent first being granted, as it could easily be a waste of their time. It is not uncommon for Council to request changes to the plans as part of their peer reviewing processes for engineering and design.

During and after the renovations process, you will need inspections from the Council. At the end you will get the final sign-off, called Producer Statements (PS). Not only are these important to show that the Council has approved the completion of your work, but if you do not have the appropriate consents, you will not be able to get insurance cover.

Further, you will also find it very difficult to sell your home without the relevant Code of Compliance or PS. Banks and lenders are increasingly looking for reasons to not give a loan or mortgage. The absence of Code of Compliance documents will be all that is needed.

Major Renovations For The Whole House

It is not just updating your kitchen and bathrooms – a major renovation often includes multiple spaces of a house.

These days people tend to want to have a big open-plan living area. So it is common for us to work on major renovations in Coatesville that include the kitchen, lounge, dining room, and hallway for example. With our major renovations building experience we can help create much more living space in a house by removing walls to reconfigure the layout, giving views across the garden or creating much brighter internal living spaces.

Other major renovation projects can include adding an upper-storey or perhaps building out over a garage to add bedrooms or an office. Adding a granny-flat is another popular addition, which can often be part-funded by the parent selling their home, or rented out to gain extra income.

Major Renovation Projects Can Involve Indoor And Outdoor Upgrades

Upgrades and big renovations don’t need to be exclusively focused on a home’s interior. The exterior of a home can also be part of the renovations. If you have created a wonderful open-plan living area, lots of people choose to carry that outside by having a new deck, patio, or outdoor living area built. This way, you can extend the theme throughout your home, creating a steady flow of colour and style.

Another advantage in having major renovations in your garden at the same time as the indoor renovation building work, is that you only have one time of disruption. You might as well “get it over with.” The building company is on-site so they can build the deck or patio for you. The Project Manager can work with the other trades companies for landscaping or outdoors electrics for example.

If people put off the idea of renovating their garden or outdoor living area, they will find it harder to get the enthusiasm at a later date so we always recommend having the indoor and outdoor renovations done at the same time if your budget can handle it.

Major renovations builder CoatesvilleThe Costs Of Home Renovations Can Vary Wildly

One of the first things that most people want to know about home renovations is how much they cost. Unfortunately, there isn’t necessarily an easy answer to this question. There are many things that impact the total cost of home renovations.

Upgrading a small home is generally going to be cheaper than improving a larger home unless expansions are involved. Some homes may not need extensive renovation work, but other properties are going to need significant upgrades.

One of the best options for you is to call in an experienced home renovations builder to talk through your ideas. They can then give you a ball-park figure so you can see if that fits with your budget or your valuation for a renovated house in the area.

These days with the quickly changing costs of renovation building work in Coatesville, in fact throughout New Zealand, your own estimate is likely to be some way of the mark. Don’t leave it to chance and start a project that you cannot afford.

Summing Up

In short, there are many ways of renovating your home to create more space, light, or add value. If you have some thoughts about a major home renovation in Coatesville, and would like some advice, please call us on 0800 224 628 or email at, we’d be happy to talk to you about your options.





House Extension, Coatesville Builders, Some Ideas From Cain Built

Benefits Of A House Extension, Coatesville Builders, Cain Built, Have Some Ideas

If a family decides they need more space, they have two main options; to move to a bigger home or to build a house extension. For many the idea of a house extension has more advantages than moving to a new home. As a house extension builder in Coatesville, Cain Built have experience working with families, helping them to overcome their space problems by building a house extension for them. In this article, we will be going over some of the benefits of a house extension.

1. You Know The Area

If you have children then you will know the challenges of getting them to accept the idea of leaving their friends and moving to a new area, new schools, new sports clubs or activities. This is not to be under-estimated.

And don’t forget yourselves either. You will have your circle of friends in the area. Making new friends is not easy so do pay serious attention to this issue.

2. Increase The Value Of Your Home

Another key benefit that you will get from having a house extension built is that you are investing in your current asset, and increasing its value. Given the current house prices in the Coatesville area, if you move to a new home, you will face legal and real estate agency bills of well over $50,000. That is dead money.

Instead, you could invest that money as part of the cost of a brand-new house extension. You will need more than the $50,000 for a completed house extension project of course but that is a significant contribution from which you will get value rather than simply handing it over to agents and lawyers.

In addition, you are going to increase your value of your home, which in time, will make it much more marketable when you do want to move home. That $50k+ investment will be one of the best returns you will get, especially compared to the other option.

3. Make It Your Own

Another benefit that you will get from building an extension to a house is customising your home to make it your own. There may be aspects of your home that you don’t like. Maybe the layout doesn’t work, perhaps some rooms are a bit small, or the sunlight doesn’t shine in where you want it. All of these are issues that you can change if you have a house extension built. By definition, you will be increasing the overall size of your home by extending it, but these other layout issues can be tackled at the same time.

Often when we have worked on a house extension in Coatesville and surrounding areas, we have not just added space by building out, we have changed the internal layout too to accommodate the family’s desires.

Do you want a new bathroom? Maybe you are adding a sunroom or something else. All of these you will be able to include in your house extension building project to make your home much more useable for you.

4. More Space.

As noted above, often a big motivator for families looking to move is that they want more space. Growing teenagers, more children, or aged parents coming to live. All of these are very common reasons for people wanting to have more space to live in.

Moving home is a massive task. You have to decide where you want to live, visit real estate agents who will hound you once they have your phone number, go to lots of open homes, make offers that might get beaten by other buyers, organise finance, and if all of that is successful, then you have to go through the move itself. It is an arduous process.

Much simpler, even though there will be building work and disruption, if you are looking for more living space, is to have an extension built. Many homes, especially older ones, do not maximise the usable space in and around a home. With good design, and modern building techniques and materials, you will be able to add more living space to your property depending on Council approval of course.

6. Luxury From a House Extension

Another reason that people think of moving is to upgrade the quality of their home. Older homes deteriorate; it’s natural. It seems like a good idea to move to a new house. But you can often get a similar or even better result by upgrading your existing home.

When you add a house extension, that automatically adds a feeling of elegance, because of the extra space. But at the same time, you can upgrade other parts of your house. A new bathroom, a kitchen renovation, opening up rooms to create a bigger living space. All of these can be part of a house extension building project. Each of which, and cumulatively, will add a feeling of more luxury to your home.

Move or Work With A House Extension Builder in Coatesville?

In the end, only you and your family can decide which you feel is right for you. However, instead of moving, you might want to consider investing in a house extension. It is a good way to increase the overall value of your home, it adds much-needed living space, you can add a sense of luxury to your home, it is often easier than moving, and, it means you can stay in the Coatesville area rather than having to uproot your family, and start again in a new suburb.

If you would like to have a chat about the possibility of a house extension, please call us on 0800 224 628 or email at, we’d be happy to talk to you about your options.

Window Selection Balancing Act

Windows provide more than just a view on the world outside. They need to multi-task, bringing in light, allowing solar gain as free winter heat, admitting fresh air and limiting heat loss in winter.

Window area and specification has a huge influence on the overall energy efficiency of a building, and often this is underestimated.

This article from Build Magazine explains the benefits of installing properly insulated glass and what to look for when making your selection.

East Coast Bay Home Extensions Builder – Some Thoughts

Five Reasons You Should Consider Having A Home Extension Built

As a homeowner, one of your biggest concerns may be the lack of enough space. Even if you think you have plenty of space at the moment, at some point, you may decide that you need some extra room in your home. Moving to a bigger house is always an option, but the hassle of relocating isn’t everyone’s cup of tea. Exploring the option of building a home extension is definitely another option you ought to consider since it gives you more control over the final result.

Further, there is more to home extensions than just having more space. If you do not have to relocate for a job, extending your home offers numerous other benefits too that are worth considering.

Building A Home Extension Saves You Time And Money

The implications of purchasing and moving to a new home cannot be overlooked. The process of assessing, viewing and bidding on a home is expensive and emotionally draining. There is also no guarantee that you will be able to buy a house that you like if someone outbids you. In addition, there are significant costs associated with moving too; legal fees, real estate commissions, and the removal company. That is all on top of the time and expense looking for a house.

Building a home extension is not a stroll in the park but for many families, it is much less disruptive as you do not have to relocate. For example, you do not have to find new schools and get the children settled in to those, which is another emotional drain.

Building a house extension is not a cheap option but at least the outlay is going into your asset rather than commissions to service providers.

It Adds Value To Your Home

It goes without saying that a home extension raises the value of your property. Increasing the value of a home is not usually a driver for people who decide to have a home extension built. It is usually the need for more space as youngsters become teenagers, or an elderly parent wants to move in with you.

Nonetheless, a well-designed and constructed house extension will add value to your home. However, seek advice from architects, local real estate agents, or experienced house extension building companies regarding over-capitalising your home. For example, if you make your house into a five or six-bedroom home but all the others in your street are four bedrooms, then it might be difficult to sell a house that big in your neighbourhood.

It would be prudent to consult one or more of the above experts before you go too far down the track.

An Extension Can Adapt Your Home To Your Changing Lifestyle

A home extension helps you gain the much-needed space to suit your family’s lifestyle. You may need the extra space to accommodate extra family members, or the desires of your family might change. When children are small they often share a bedroom no problem, but as they grow older they may want their own space.

Another example is if you decide to work from home. You may want an office or studio, depending what you do. Or you may decide to create an open-plan living area which you can extend out into the garden to add even more living space.

Whatever your family’s wants or needs might be, the extra space you gain from having a home extension built will allow the installation of extra facilities and resources to ensure that your home adapts to your new lifestyle.

A New Home Extension Can Change Your Home’s Interior Design

If you are going to have a building company to add a home extension, there will be some disruption for sure, and will probably require remedial decorating where the house extension meets the existing walls. That is an ideal time to have a fuller refit, or redecorate your home. You could even take the opportunity to go all out with your design options.

Extra Facilities Give More Convenience And Family Harmony

Having extra bathrooms or kitchen space is invaluable to any home setting. As a family expands there is more demand on the existing facilities. What family hasn’t had a struggle with the queue for the bathroom on schooldays? A house extension including an extra bathroom brings harmony and efficiency to the running of a home.

If you have extra kitchen and dining space this can help to enhance the relationship between family members. Dinner time used to be when families got together at the end of the day and interacted with each other. But these days it is not as common as it used to be. However, if you have a well-designed, and more conducive dining area, you can bring back those valuable family times.

Self-build Or Hire A Builder For A Home Extension?

Some people may be tempted to build a home extension themselves. The old Kiwi-DIY spirit. But these days it is a much better idea to hire a building company for a home extension.

Some of the main reasons are that for one, people are much busier than they used to be. Life is lived at a faster pace, and spare time is more limited. That means that it will take a lot longer to complete the job if you try it yourself.

Another issue is that the building regulations have changed significantly. Many jobs can only be signed-off by the Council if they are completed by a licensed trade provider.

That leads onto the next big reason; Insurance. Insurance costs have gone up massively in the last two years, and insurance companies are looking for excuses to not take on new risk. But you will only get insurance cover if the work has been given all the Council building consents.

Summing Up

Often the first thought about a cramped housing issue is to look for a new home, but there are other options. One of the best is to hire a building company to build a home extension. This will not only enhance the value of your home, and provide you with the extra facilities that you want, but it will ensure that the home extension will have all the necessary building consents.

East Coast Bays Basement Renovations Builder

A Basement Renovation To Make More Space In Your Home

A basement renovation is without doubt one of the best ways to add extra usable space to your home. In many cases it is more cost-effective than adding another full or part-storey to your home which can require strengthening of the lower levels.


Also, adding a storey or filling in space on your home changes the aesthetic look of the building. For many houses, this addition to the structure can look ugly or at least out of character with the architect’s original designer. A basement renovation or extension on the other hand, is largely below ground and therefor has little impact on the overall look of your house.


How Do You Want to Use Your Basement?

The most important question is to ask yourselves, “Why you want the basement renovation?” For some people they simply say they want more space but with better questions, you can get a much clearer definition of your desired outcome.


When you have a better definition, you can give better direction to the designer or architect, which will mean they can draw up the plans for your basement renovation project so it’s fit for purpose.


Having a clear idea of what you want at the end of the basement extension work means that you will be less likely to make changes along the way after the basement renovation builder has started their work, which can cause delays and incur additional costs.


Below are some ideas for basement renovations, to give more room to your home.

Rumpus Room

One of the classic uses of a basement is for a rumpus room for young children. They can keep their toys, downstairs away from the tidier adult areas like the living room. It can also be quieter when the children are playing downstairs in the basement renovation.


Also you can have floorings and wall coverings that are child-friendly which you can clean easily without the concern of damaging your living room walls or carpet.

Granny Flat in Basement Extension

At the other end of the age range is your parents. As they get older they often need help or they simply don’t want to live in a large family home as they have done previously. This is especially the case if they have lost a spouse.

As a result, many families take in their parents and either provide them with a bedroom in the main part of the house or, better still is to convert a basement into a granny flat. This gives the best of all worlds. The grandparent is close by, but they have their own living area with more privacy, and a place to rest. A nana nap anyone?

Teenager’s Basement Room

When children are young, they often like sharing their bedroom with their siblings. But as they get older and become teenagers, the idea of sharing with a sibling is,….well, we know the outcome.


So one solution is for one teenager to stay in the existing bedroom, and to turn your basement into a room for your other teenager. This gives both children privacy, and more space to bring home their friends without disturbing the rest of the household.


Bar or Cellar

Many people like the idea of having a bar in their basement. Somewhere that they can have friends around in a convivial atmosphere. Beers on tap, a fridge, a dart-board maybe. Just like being down at the pub.


More recently people have had the idea of creating a wine cellar and tasting area in basement renovations. The room is likely to be both cooler and darker anyway being underground, which are both important aspects for storing wine.

Entertainment Area or Home Theatre

Home cinema basement renovationAn increasingly popular use of a basement renovation job is making the room into an entertainment area. This can be an extension of the bar theme with a pool table too. Or, in recent times, many people have had a home theatre or media centre installed.


This could range from a few chairs and a big screen TV to lavish seating with full surround-sound and film projector.


Guest Space

Basement bedroom renovation

Perhaps you want to add space for visitors staying at your home. This might be family or friends, or you could make it into another income stream and convert a basement for home-stay overseas students or Airbnb.



Another idea for converting a basement is to make an office space. If you are self-employed or run a business from home, this is a great idea since it gives you a more peaceful space to work in, and it also keeps your papers etc away from the family living areas. Not only does this make the living areas tidier but it also means that little fingers don’t make off with important documents.


How to Build a Basement Extension?

There are essentially two ways to build a basement renovation. You either dig out the ground, or you can fill in an open space below the house. On the hilly Auckland roads, there are plenty of homes with unused space beneath the main home. Enclosing the space with external walls is a relatively easy basement renovation method and can produce some fantastic basement renovations.


Summing Up Basement Renovations

A basement renovation can give you a lot more room in your house. This is often easier than selling and buying a new home, especially if your children are at school.


A good basement renovation builder with the right plans can also add considerable value to your property without significantly affecting the overall external appearance of the building, therefore maintaining the integrity of the original design.


If you want more space in your house, consider a basement renovation. We are happy to come along and have an initial chat to give you some ideas of what might be possible with a basement extension in your home. We can give you the benefit of our experience on similar basement renovation projects we have worked on.

East Coast Bays Second Storey House Extensions Using Pop-Top Renovations

Why Second Storey House Extensions Using Pop-Top Renovations Are A Great Way To Increase The Space And Value Of Your Home

Second storey extension

For many homeowners who want more living space, moving is not always the best option. Adding to the available space that you already have is often a better choice than selling your house and finding a larger one.  Adding a second storey or pop-top renovation to a home can be a good way to expand the usable space but will need some extensive renovation work.

Four Ways To Build Upwards For More Space

There are four common methods to expand upwards with a home renovation.

Second storey renovations Dairy Flat

Add a second storey to your home

One is to take off the roof, then replace it after the frame for the new storey has been built. This is a good idea if your land space is limited. However, adding a second storey will be more expensive than extending outwards at ground level but sometimes there is no choice.

Another option is to extend the second storey across an existing one-storey structure, like a flat-roof garage for example. This is an easier option but has two main disadvantages. The first is that it means a limited expansion. The second is that it will change the external look of your home and it is not always a visual improvement.

The third method is to have a loft conversion if you have the roof space. However, the floor of your attic was probably designed as a ceiling so it might not be strong enough to support a second storey. This can require some expensive strengthening work.

The fourth option is the one we look in-depth at and that is to add a pop-top or second-storey house renovation. This is where the homeowner decides that they don’t need space across the whole floor but in just a limited area. Rather than adding a full second storey, a pop-top adds a new room or maybe a master bedroom and ensuite.

Which Renovation Type Do I Need?

The key to a successful renovation to increase the usable space in your house is to ask one simple question.

How much space do I need?

If you are going to go through the disruption of a major house renovation, there might be a temptation to think about “going the whole hog” and adding a lot of extra room. For any extension you will need to include:

  • Structural work
  • Roofing
  • Plumbing
  • Electrical
  • A new staircase
  • Decorating
  • Carpeting

But for each additional square metre you add, additional costs can be quite significant. As a ball-park the price can increase by:

  • Basic Quality Extension – $2600 – $3300 per square meter
  • Good Quality Extension $3300 – $4500 per square meter
  • Excellent Quality Extension $4500 upwards.

If you decide you do need a lot more space, then it would be more cost-effective to go for the big renovation at one time rather than adding further rooms a few years later. However, often people don’t fully utilise the extra space they pay for. So it makes a lot of sense to be honest to yourself about the extra space you really need rather than having a grandiose desire.

You also don’t want to over-capitalise in your suburb. For example, if you live in a four-bedroom suburb, then expanding to a six-bedroom house will over-capitalise.

The key is thorough and realistic planning to make the best use of your money.

Adding A Pop-Top – An Effective Solution For Creating More Living Space

Add a new living room in your second storey extension

One of the biggest problems people have, especially on an already sub-divided section is the area of their land. Extending outwards is not always possible so if you decide that your family only needs an additional bedroom or maybe a playroom, then a pop-top can be the best way forward.

You are limiting the extra square metreage that you are paying for. This will reduce the roofing costs, the decorating and floor covering. Electrical work will be a lot less, and, depending on the use for the new pop-top space, your plumbing expense could be far lower than with a full storey extension.

An additional visual benefit is that a pop-top roof can be made to look an integral part of the building design. Compare this to squaring off the building by adding a room over a garage. That can look “boxy”, and not very appealing. But a pop-top can make an elegant addition.

Also, if it is going to be a master bedroom suite, which second storey renovation extensions usually are, you will enjoy a bigger and better view from your windows.

How Much Will A Second Storey Pop-Top Extension Cost?

The price of a pop-top extension can have a big variation in price. They can range from $200,000 to $450,000+.

Dairy Flat second storey extensions

Or add a master suite

There are various factors that affect the ultimate price of a second storey renovation to include in your budget. One of the biggest issues will be the choice of materials, especially if you are having a bathroom since prices vary considerably depending on the quality of fittings you choose.

You will need to include planning costs, architectural drawings, Council permits, and of course the renovation builder costs themselves.

Also be aware, that the more changes you make during the pop-top construction process the more expensive the end project will be. It costs a lot more to retro-fit work the builder has already done than to plan it properly to start with.

It also pays to have a contingency in the budget as you will undoubtedly have unplanned costs. Aim to include 10% to 15% of the build cost.

Some Issues To Consider For Adding A Pop-Top Second Storey Renovation

When you are building up rather than building out, you have to take into account a few pointers.

For example, the pop-top will add extra weight to the house. An older home might not be structurally capable of supporting the extra weight so you will need to get an engineer’s report to see if you have to strengthen the lower parts of the house.

You will also need additional scaffolding and shrink-wrap to keep the working space dry. This does mean though that the builders can work through bad weather conditions making your build quicker which offsets the wrapping cost against the labour cost.

The first step in the process is to have detailed plans developed by an architect along with the engineer’s input.

The Best Way Forward To Adding A Pop-top House Extension

The first step is to talk to an experienced License Building Practitioner. They will be able to come out on site to have a general chat about your ideas.

They will be able to say if you need planning permission for example. This will be a lot quicker than asking the Council.

They will also have some good ideas and suggestions based on their experience in doing other pop-top renovations. They can also give you some pointers on the costs of different ideas you might have.

While these are suggestions you will need plans drawn up for the Council to approve and the builder to work from. A good renovations builder will know good designers they can recommend for your project to produce those drawings. This can save you a lot of time and money talking to a number of designers or architects.

A pop-top renovations builder will also be able to give you a ball-park figure for the work you have in mind. This will mean you can see if you can afford the job, or if you need to scale back your intentions.

Whatever your situation, contacting an experienced pop-top renovations builder at the start is your best way forward.

At Cain Built, we have worked on pop-top renovations in various parts of Auckland. If you want a second storey or pop-top renovation in East Coast Bays or other areas of the North Shore, call us on 0800 224 628, or email us at We will gladly come and have a chat with you about your aims for a pop-top renovation.

Fixed-price Vs Charge-up contracts – which is best suited to your project?

Typically, there are two types of building contract used in New Zealand – fixed-price contracts and charge-up (also known as cost-plus-margin contracts), though knowing which of these contracts to go with can seem daunting, with usually either being suitable options. As both come with their advantages and disadvantages, it’s important to understand these differences before you sign so you can decide which best suits your project, budget and preferences and to avoid any surprises down the track. At Cain Built Ltd. we’ll recommend which style of contract we believe will work best for you, answer any questions you may have and give you ample time to consider everything before making your decision.

So, what are the differences?


Fixed-price contracts

In a nutshell – we’ll give you a detailed quote, up front.
Best suited to: New Builds and those who know exactly what they want.

A fixed-price quote can offer a certain level of certainty at the outset of your build, so if you have a very specific budget, or if you need a figure to take to the bank for approval, this contract will likely best suit you.

The price shown on your contract will generally be what you end up paying. We say generally, as it’s important to note that these contracts can include exceptions and certain ‘tagged’ items in your build (common in renovations, but can arise in new builds as well) where a price cannot be confirmed until work begins, as often there are elements of the build that can’t be seen or are unknown prior – such as; variations to initial plans, issues found once work has begun (e.g. rotten timber, asbestos) excavation and earth moving surprises (e.g. unfavourable conditions or excessive ground water, contaminated soil, discovery of pipes not on the supplied plans, tree roots).

There is always the possibility of additional costs. With our fixed-price, we will give you a set price with a breakdown of materials, labour and subcontractors required, along with a detailed scope of the work, so you know exactly what is and isn’t included. Variations to the scope of works will either be quoted or billed out on a cost + margin basis. Additional to the cost of the work done there will be an administration fee to cover the time spent pricing and the additional administrative work resulting from the variation. Variations may also result in delays to the job schedule leading to additional costs to the builder not allowed for in the fixed price contract – to name a few; additional rubbish removals, extended hire of fencing, plant and even toilets may result from a variation of which the cost is passed to the client.

Cain Built work with a qualified Quantity Surveyor, so we can ensure your quote is as accurate as possible, based on the plans and information you provide us. As it can take anywhere from 30-60 hours to accurately price a large project, please be aware there is a cost involved with supplying you a fixed-price quote. This cost however is waived if you choose to use us as your builders.

We find this way of working delivers the best building experience as the job typically runs more smoothly – you know exactly what to expect from us from the get-go, so the potential for disputes or disappointment is considerably lower.


Charge-up contracts

In a nutshell – we’ll give you an educated estimate of the project cost before you start. Generally, we will work off square meter rates for the type of project and previous experience. The figure given is more of an indication of cost than a fixed sum.
Best suited to: Renovations & those that want flexibility to make changes as the project progresses.

This type of contract includes the builder’s cost price of all materials and sub trades plus the builder’s margin, so we’ll only charge you for the hours of labour and materials used on the project as we go, as opposed to a pre-estimated set cost, though exceptions and ‘tagged’ items may still apply to this type of contract.

With charge-up contracts you have greater flexibility to make changes as the project progresses and reassurance of paying only for the labour and materials used as opposed to a generous assumption. If the project runs ahead of schedule you reap the benefits. It also means you’re not paying for contingencies made during pricing to allow for unknown issues which builders must do in fixed-price contracts.

Starting with only an estimate does means it’s harder to know what the exact final cost will be at the end, but we can arrange to have a high-level estimate produced by our Quantity Surveyor so you can see where the allocation of costs are and where money can be saved.


At the end of the day.

Our Cain Built team always aim to deliver on time and on budget, no matter the type of contract we have with you. We will organise everything from contractors through to the final inspection for you, so you don’t need to run around gathering further quotes for trades or worrying about orchestrating them all – you can leave all of that to us and it will all be outlined in your contract. Furthermore, both fixed-price and charge-up contracts allow you to take advantage of our industry discounts on materials and trades, so you get the best price possible.

We also understand your thoughts and ideas may change as you start to see your build take shape and that’s ok – you can still make changes to a fixed-price project as it progresses if need be. We will discuss your options with you at the time and what this will mean regarding your contract.

Whichever you decide to go with, we’re here to offer you advice and a positive building experience.



About Cain Built Ltd

About Cain Built Ltd


Cain built Ltd. was founded in late 2014. Having worked for building companies for nine years, I decided the time was right for the next challenge – establishing my own business.

Over these past years, I really have nearly seen it all: renovations, top-end new builds, alterations, extensions, re-clads, re-builds and commercial work. This gives my team a competitive edge when it comes to approaching your next project, as there isn’t much we haven’t come across. In particular, renovations are something that we thoroughly enjoy. Yes it’s dirty work, but it’s also extremely rewarding turning a house that’s essentially a crude stone into a polished diamond.

We strive to deliver the highest quality workmanship to our clients, and as a member of the New Zealand Certified Builders Association, we’re able to provide you with a Halo 10 year Residential Guarantee Insurance to back that up. This provides you with peace of mind that your project is being built by trade professionals, who are backed by the most comprehensive guarantee on the market.

Our story



When I set out to find a building apprenticeship times were tough and opportunities were scarce. Despite this, I was accepted into a labour company’s apprenticeship scheme. From there I had to serve out a trial period, at first labouring, to prove I was going to uphold their name and honour their financial commitment to me.
After labouring, I began my apprenticeship with Wayne Jensen at SCD Builders. Here I was placed in the care of 3 builders, who between them had over 80 years experience in the industry – I couldn’t have asked for better people to learn from. Each offered different areas of expertise and I soaked up their knowledge like a sponge.
With Wayne and the team, I worked on commercial office units and renovations. I also assisted the team on building a number of new houses – a highlight being a country estate for one of our country’s wealthiest people.
