Licensed Home Extension Builder Bronte
NSW licensed extension specialist. Bronte 2024 extensions on 1900s–1940s + apartments-era homes require structural sign-off, Class M footings, and matched connection — we engineer and document properly.
Quick Answer
A home extension in Bronte costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Waverley Council approvals, and construction under one fixed-price contract.
Home Extension Builder in Bronte
A home extension in Bronte almost always ends up being about the view. The defining project here is an upper level that lifts the living up over the gully or out to the water — engineered onto the early brick where the controls allow it — because that outlook is what the whole suburb trades on and most single-storey originals waste it entirely.
The heritage streets keep their frontages, salt-grade materials are standard this close to the surf, and where the blocks drop toward the beach the fall is engineered rather than assumed. The pre-war fabric carries lead and asbestos, handled under licence.
At a $3.5M to $10M median, that view level is comfortably the most valuable room you can build — and the beach-village life below it stays exactly as it was.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the view potential assessed, before you commit.

The view level pays for itself
Bronte's premium peaks with the ocean view, and an engineered upper level claims it where the controls allow — transforming what the home is worth while the beach-village life carries on below.
The conserved frontages keep the streets the suburb is loved for.
Salt, fall and fabric
Salt-grade materials are standard, and the fall is engineered where the blocks drop toward the beach.
The pre-war fabric's asbestos and lead are handled under licence, and all of it is priced into the job from the outset.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Bronte homes from the 1900s–1940s + apartments 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.
