Home Extension Builder in Belmore
A home extension in Belmore is an older-fabric job, and that shapes everything. The homes near the station are 1930s to 1960s, and the inter-war character out the front is exactly what the market pays for — so the frontage stays, and the new wing goes in behind it where nobody on the street can see it.
Working with pre-war fabric means lead paint sits alongside asbestos on the checklist, and both are handled as licensed processes. Where the new wing ties into the old structure, the aged footings get assessed rather than trusted, because a century-old footing and a new slab do not always agree without help.
At a $1.2M to $1.5M median, keeping the character at the front while adding modern living behind protects what the house is worth and gives the household what it needs.

Character stays, living goes behind
Belmore's inter-war homes extend the right way — the character frontage is left alone and the wing builds a modern kitchen, dining and family room across the back, invisible from the street.
The station and local amenities keep the finished result firmly in demand.
Old fabric, proper process
Lead paint joins asbestos on pre-war fabric, and both are dealt with as licensed processes rather than disturbed and ignored.
The aged footings are assessed where the wing meets the old structure, and all of it is priced into the job from the outset.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. On-site assessment of your 1930s–1960s-era home in Belmore. We check structural condition, block dimensions (500–700m²), setback availability, and Canterbury-Bankstown Council's DCP requirements. Written feasibility and cost estimate provided. Designing an extension is half about the new space and half about how it joins the old one. Doorway position, ceiling height transition, floor level matching, light wells — the junction makes or breaks how the finished home feels.
⏱The Belmore construction phase. Fixed price, programmed, supervised. We lodge your extension approval — CDC for eligible designs or DA through Canterbury-Bankstown Council. Full documentation including structural engineering for Class M soil, BASIX, and shadow diagrams. CC issued before works start. For ground-floor rear extensions you usually stay in the house during the build, with temporary weatherproofing at the junction wall until the new section is locked up. Second-storey additions need a 4–8 week relocation during the roof-off and frame-up phase.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection, Occupation Certificate, 6-year structural warranty. Your Belmore home now has the space your family needs.
⏱Quality Promise
Our Belmore home extensions connect old-to-new cleanly. Matched brickwork, tied roofline, no awkward transitions.
