Home Extension Builder in Hunters Hill
A home extension in Hunters Hill answers to heritage first — conservation areas cover virtually the entire LGA, and the addition works behind conserved Federation and Victorian frontages on 500 to 1,200m² blocks.
The sandstone fall shapes the engineering, the pre-war fabric gets licensed handling, and the peninsula's premium standing rewards the work done exactly.
At the $3.5M to $6.5M heritage median, the wing protects a position that rarely comes up again.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the heritage position checked, before you commit.

Heritage covers the peninsula
Hunters Hill's conservation areas cover nearly every street — so the addition works behind the conserved frontage, sympathetic in form and material to what the peninsula is known for.
The premium standing rewards the work done to conservation grade.
Fabric and fall handled
The sandstone fall shapes the structure, and lead paint joins asbestos on the pre-war fabric — licensed processes both.
The slope engineering and the licensed strip-out are both costed up front.

How It Works
From First Call to Final Key
Free consultation at your Hunters Hill home. We inspect the existing structure, check Hunters Hill Council's controls, measure available space, and discuss what you need.
⏱Two design moves are usually on the table: match the existing house so the extension reads as original, or contrast with it so the new section is clearly modern. Both work — choice is aesthetic, and we'll show 3D renders of both before you commit.
⏱CDC (10–15 business days) or DA through Hunters Hill Council depending on scope. Structural engineering, BASIX, and all documentation prepared and lodged.
⏱Construction phase connects new to existing — footings, frame, roof tie-in, waterproofing at junction, internal fit-out and external finish. Staged works minimise disruption to your daily routine in Hunters Hill.
⏱Final inspection focuses on the integration: paint blend, flooring transitions, ceiling height, junction waterproofing, sound transmission. The extension shouldn't feel bolted on — it should feel like the house was always meant to be this size.
