Christchurch Building Conditions – What You Need to Know
- When building an extension in Christchurch, you’ll need to take into account:
- Earthquake strength and land classification (TC1, TC2, etc.)
- Zoning rules such as height-to-boundary restrictions and minimum setbacks
- Flood and drainage overlays that may affect floor levels and materials
- Christchurch City Council or Selwyn District Council consent requirements
Our specialist experts work with architects, engineers, and planners to construct every extension to your liking and within necessary regulations
Extending your house is always a workable option to create more living space without the hassle that comes with relocating. We provide a full package in designing and constructing extensions that effectively match your current house, whether functional or aesthetic, or both.
Our team will not only appraise your property for the type of extension that best suits it, but also discuss with you all the needs and take you through any local council regulations so that your extension meets the criteria for potential additions and compliances.
The extra bedroom, larger kitchen, maybe the new living area-we can build it all for you. Look no further for all this and more, as our expert builders are here to make it happen for you.
There are a few important steps and considerations to keep in mind:
- Building Consent: Most house extensions will require a building consent. This is necessary for any structural work, additions, or significant alterations. Ensure your plans comply with the Building Code and check with the Christchurch City Council to see if your specific project requires consent.
- Resource Consent: Depending on the scope and impact of your extension, you might also need a resource consent, especially if your project affects the environment, heritage sites, or neighbouring properties.
- Planning and Design: Before starting, it’s crucial to have a detailed plan. Consider your budget, the extension’s design, and how it integrates with your existing home. Hiring an architect or a professional builder can help streamline this process and ensure all regulations are met.
- Professional Help: Using licensed tradespeople is essential. They ensure the work meets safety and quality standards and handle the necessary paperwork for consents and permits.
By following these guidelines, you can successfully add an extension to your home, enhancing its value and functionality. For detailed information, you can consult the Christchurch City Council’s resources or visit the New Zealand Government’s renovation guidelines online.
House Extension Design
Designing house extensions is not only about adding rooms; rather, it is all about harmonious flows between old and new. Extension design with us includes comprehensive services that closely work with you to understand your vision and translate it into a practical and beautiful reality.
We take into account natural light, the style of architecture, and your lifestyle needs to make it work in design for your home. Our team works for you to ensure the extension feels like a part of your home, including the much-needed extra space.
Home Extension Plans

Our home extension plans cater to your needs and budget and don’t even leave out a single minute detail. We work in tandem with architects and engineers to provide plans that are not only pleasing to look at but also have structural integrity so that the new space adds functionality and value to your home.

Yes. We take great care to blend materials, roofing, cladding and joinery so your extension looks like part of the original home.
How long does a home extension take to complete?
A small extension can take 8–12 weeks; larger or double-storey projects may take 4–6 months, including consent timelines.

Will a house extension add value to my property?
A well-designed and executed house extension can significantly increase your property’s value by enhancing its functionality and appeal. However, the actual value added depends on factors such as the quality of workmanship, the type of extension, and current market conditions.
