Ashbury Home Extensions — Fixed Price
A home extension in Ashbury works one of the inner west's quietest heritage pockets. It is Federation bungalows on 350 to 650m² blocks along genuinely tree-lined streets, and the calm of the place is the whole appeal — so the wing goes in behind the conserved frontage, adding the family space while the streetscape stays exactly as it is.
The pre-war fabric sees its lead and asbestos cleared under licence, and the bungalow character out the front is a real part of what these homes are worth — which is why the addition is kept behind it rather than allowed to overwhelm it.
At a $1.8M to $2.6M median, a wing beats trading out of streets this settled — the quiet, leafy character is hard to buy back once you have left it.

The quiet pocket grows carefully
Ashbury's Federation bungalows on tree-lined streets extend the right way — conserved frontage, family wing behind — with the settled character the whole point of staying.
The 350 to 650m² blocks fit the addition with the design worked properly.
Fabric handled properly
The pre-war bungalows carry asbestos and lead paint, both handled under licence.
That work is in the fixed price from the outset rather than tacked on later.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Ashbury homes from the 1900s–1950s were built to different standards — we open walls, check footings, verify load paths. The existing house has to carry the new work.
⏱Design follows the existing roof. A bad extension looks like a bolt-on; a good one reads as original. Matched brickwork or contrasting render (whichever the architecture calls for), tied-in roofline, continuous flooring where it should be continuous.
⏱Construction happens while you live in the house. That means weatherproofing every night, staging the works so kitchens and bathrooms don't disappear on the same week, and keeping the site clean of debris that doesn't belong in a family home.
⏱Finish is seamless. Paint match, floor match, roofline match, brick match where possible. The only way to tell the extension is new is the date on the plans.
