New homes and home extensions in Canberra
A successful build starts with a clear brief. Whether you need a new home, a ground-floor extension or more space upstairs, the first step is to understand your property, the way you live and the scope you want to achieve.

What affects your home extension quote?
Floor area is only one part of the picture. A useful building quote needs to account for the existing home, the proposed structure and the level of finish. A site-specific discussion helps establish the information needed before pricing can be reliable.

- Existing plans, site access and the condition of the building01
- Number of storeys, structural changes and connections to existing services02
- Kitchen, bathroom, window and finish selections within the scope03

THE DETAILS MAKE A DIFFERENCE.Good questions.
Better beginnings.
Your building questions,
answered.
Practical information for planning your project. Scope, availability and the next steps need to be confirmed for your property.
01Can you discuss both new homes and extensions?
Yes. Enquire about a new home, a ground-floor or second-storey extension, or a home transformation. Include your Canberra suburb, the spaces you need and any plans you already have so suitability and availability can be confirmed.
02Should I renovate or extend my home?
Start with the problem you are trying to solve. Reconfiguring existing rooms may improve how the home works; an extension may be needed when the floor area itself is the constraint. Site conditions, budget and the existing building will influence the options.
03Do I need complete drawings before requesting a quote?
You can begin with an idea, sketches or inspiration. A detailed construction quote will require enough information to define the scope. Design work and any necessary specialist input should be agreed for your project.
04Can I live at home while an extension is built?
That depends on safe access, service interruptions, structural work and the separation of the construction area. Discuss occupancy early so staging and any temporary accommodation can be considered in the project plan.
05What should I send with my enquiry?
Include your suburb, a description of the additional rooms or changes, your preferred timing and any available plans or photographs. An indicative budget is useful if you have one; you can also explain which decisions are still open.
