A home extension in Matraville is the sensible-middle play in the east. It is post-war homes on 500 to 700m² blocks with genuine rear depth, at entry prices the beach ring simply cannot offer — so a wing here buys real family space without the eye-watering cost of getting closer to the sand.
The read leads: sound brick takes the wing, tired fibro gets a rebuild comparison, and the Federation pockets extend the character-behind way with the frontage kept. The post-war fabric gets a licensed asbestos strip-out where the work opens it up, and the sandstone keeps footings straightforward.
At a $1.7M to $2.6M median, a wing beats the cost of upsizing eastward — the eastern-suburbs position holds the result while the block depth lets you build the space the house was missing.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.

The sensible middle grows
Matraville's mid-tier entry and genuine block depth make the wing the natural play — bedrooms, a second living space and alfresco added while the eastern-suburbs position holds the result.
If the original cannot carry the work, I set the rebuild comparison in front of you first.
Era and ground handled
The post-war fabric is checked and gets a licensed asbestos strip-out wherever the work opens things up.
The sandstone keeps footings straightforward, and all of it is priced into the job from the outset.

How It Works
From First Call to Final Key
On-site assessment of your 1950s–1970s-era home in Matraville. We check structural condition, block dimensions (500–700m²), setback availability, and Randwick City Council's DCP requirements.
⏱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.
⏱We lodge your extension approval — CDC for eligible designs or DA through Randwick City Council. Full documentation including structural engineering for Class M soil, BASIX, and shadow diagrams.
⏱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.
⏱Final inspection, Occupation Certificate, 6-year structural warranty. Your Matraville home now has the space your family needs.
