A home extension in Chiswick trades on the river. It is a small peninsula off Abbotsford, Federation and inter-war homes on 450 to 800m² blocks, and the Parramatta River wrapping around it is the whole draw — so the wing is built to open the living out to the water, with the ferry keeping the commute a pleasant walk rather than a slog.
On the conservation streets the frontage is kept and the work goes behind it, and where the blocks drop toward the river the fall is engineered rather than guessed. The pre-war fabric gets its lead and asbestos out under licence before work starts.
At a $2.4M to $5M median, a river-facing wing is a sound investment — the peninsula position is the asset, and the extension is what finally lets the house make use of it.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with heritage and fall resolved, before you commit.
Buildana manages the complete home extension process in Chiswick — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

The river is the reward
Chiswick's peninsula setting rewards a wing that faces the water — living and terraces opened toward the river, behind conserved frontages on the conservation streets, with the ferry keeping the commute civilised.
The 450 to 800m² blocks give the design room to work.
Fall and fabric handled
The fall is engineered where the blocks drop toward the river.
The pre-war lead and asbestos come out under licence, all of it in the fixed price from the outset.

How It Works
From First Call to Final Key
Free consultation at your Chiswick home. We inspect the existing structure, check City of Canada Bay 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 City of Canada Bay 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 Chiswick.
⏱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.
