Adding Another Storey to Your Home
A common approach to building house extensions is by adding another storey. If your land area is limited, this is often the better option. Naturally, this means additional weight on the foundations or concrete slab, so an important question will be: can your home support the added mass?
While we offer expert guidance on house extension designs, this is often a question best answered by a structural engineer. We can easily put you in touch with one. Our team works closely with trusted professionals to ensure your second-storey home extension is safe, compliant, and built to last.
Side House Extensions for Additional Space
If you don’t want to build upward, or if you have land available, then a side extension may be your best bet. This option doesn’t usually require foundation strengthening and can be more straightforward.
Although house extensions can be built on most terrain, a steep slope can increase the complexity and cost. Our experienced team will assess your section and provide advice tailored to your specific situation, helping you determine the right house extension design for your home.
Underneath House Extensions for Elevated Homes
For Auckland homes built on poles or elevated structures, building underneath can be a smart solution. This type of house extension maximises your existing footprint, making it perfect for properties with limited land.
Our team can help transform this space into practical living areas—such as a guest bedroom, office, or entertainment room—using smart house extension ideas that add real value.

Frequently Asked Questions About House Extensions
How much do house extensions cost in Auckland?
The cost of a house extension in Auckland typically ranges from $3,000 to $5,000+ per square metre for a single-storey house extension, depending on factors such as the complexity of the design, quality of materials, and site conditions. It’s important to note that this cost doesn’t include the cost of adding kitchens or bathrooms, architectural fees, consent fees, GST or structural engineer fees. Second-storey house extensions generally cost more (around 10-30% more) due to additional structural requirements. We also highly recommend factoring in a 10-20% contingency fund for unforeseen expenses.
At Cain Built, we provide detailed, transparent pricing after assessing your specific requirements and property conditions.
Do I need building consent for house extensions in Auckland?
Yes, house extensions in Auckland require building consent from your local council. Depending on your property’s location and zoning, you may also need resource consent. As part of our service, Cain Built handles all aspects of the consent process for your house extension, alongside your chosen architect or draughtsman, preparing and submitting the necessary documentation on your behalf to ensure compliance with the Building Code and local regulations.
How long do house extensions take to complete?
The timeline for house extensions varies based on size, complexity, and consent processes. Typically, smaller house extensions might take 8-12 weeks from consent approval to completion, while larger or more complex projects can take 6-12 months or longer. Factors affecting the timeline include consent processing times, availability of materials, weather conditions, and any unexpected issues discovered during construction.
Will house extensions add value to my property?
Yes, well-designed and professionally constructed house extensions typically add significant value to Auckland properties, often exceeding the cost of the project itself. House extensions that add bedrooms, bathrooms, or create open-plan living spaces tend to offer the highest return on investment. The value added depends on factors such as the quality of workmanship, how well the extension integrates with the existing home, and the demand for larger homes in your specific area.
Can I live in my home during house extensions construction?
In most cases, you can continue living in your home during house extension construction, particularly for ground-floor or side extensions. However, for second-storey additions or extensive renovations, temporary relocation might be necessary during certain phases of construction. At Cain Built, we work closely with you to minimise disruption and, when possible, create construction schedules that allow you to remain in your home throughout the project.
