Peakhurst Home Extensions & Additions
A home extension in Peakhurst grows the brick family home — 1950s-1990s stock on 400 to 700m² blocks where the rear wing adds the living the originals rationed and the foreshore pockets reward the water-facing design.
The junctions are engineered on the reactive ground, the era fabric gets licensed handling, and the premium foreshore lots get the salt-aware spec.
At the $1.5M to $2.4M typical, the addition beats the cost of upsizing across the district.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.

The family suburb's wing
Peakhurst's brick homes take the rear wing confidently — second living, bedrooms, an opened kitchen — with the foreshore-side lots rewarding designs that open toward the water.
The district's upsizing friction makes the maths straightforward.
Ground and era handled
The reactive junctions are engineered, the era fabric gets licensed handling, and salt-aware specs apply on the foreshore lots.
All three are costed into the scope up front.

How It Works
From First Call to Final Key
Free consultation at your Peakhurst home. We inspect the existing structure, check Georges River Council's controls, measure available space, and discuss what you need. You get a clear scope, budget range, and timeline before committing.
⏱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 Georges River Council depending on scope. Structural engineering, BASIX, and all documentation prepared and lodged. Construction Certificate obtained.
⏱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 Peakhurst.
⏱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.
