Frequently asked questions
How much does a house extension cost in Christchurch?
The cost depends on the size of the extension, the complexity of the build, and the level of finish. We can talk through your plans and provide advice on what is involved.
Do I need consent for a home extension?
All home extensions will require consent, especially where new structure, foundations, plumbing or significant layout changes are involved. We can guide you through that process. Summit’s current service positioning also references managing permits and project coordination as part of the experience.
Can you manage the full extension project?
Yes. We can coordinate the parts of the project, from planning and consultants through to construction.
