How we approach extensions
An extension has to look like it was always part of the house. That comes down to accurate set-out, floor and roof levels that line up, and cladding that matches the existing lines.
We take extensions from the subfloor through to the roof frame and cladding, for homeowners and for builders, working from your approved plans and engineering.
Most extensions need a DA or CDC, plans and engineering before work starts. We quote and build from those documents and flag anything that needs the designer's or engineer's input.

Approvals in NSW
Some outdoor structures can be built as exempt development if they meet every standard in the NSW Codes SEPP; others need a complying development certificate (CDC) or a DA from your council. Rules depend on size, height, setbacks and lot constraints such as heritage, bushfire or flood. Check your address on the NSW Planning Portal, and we will flag anything we notice when we quote.

Compare
Ground-floor vs second-storey extensions
| Ground floor | Second storey | |
|---|---|---|
| Structure | New footings and subfloor or slab | Existing structure checked and strengthened to engineering |
| Disruption | Usually less | Roof opened; more planning needed |
| Best for | Larger lots | Small lots where yard space matters |
General guide only. Product performance and warranties depend on the specific system and manufacturer.
Our difference
Why cut on site matters for extensions
Real sites are never exactly to plan. We measure the slab, walls and existing structure and cut every piece to suit, so extensions work lines up first time, with tighter joins, less waste and fewer call-backs. How cut-on-site carpentry works.
