A home extension in Beverly Hills costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Georges River Council approvals, and construction under one fixed-price contract.
Beverly Hills Home Extensions & Additions
A home extension in Beverly Hills reads era and corridor together — Federation and Bungalow homes extended character-behind, later brick extended freely, and the King Georges Road R3 checked before big spends.
The pre-war fabric gets licensed handling, the reactive pockets get engineered junctions, and the station holds the result.
At the $1.5M to $2.4M typical, the wing beats the friction of upsizing in the district.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the zoning checked, before you commit.
Buildana manages the complete home extension process in Beverly Hills — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Era first, corridor checked
Beverly Hills' heritage streets extend character-behind while the later brick moves freely — and the King Georges Road R3 gets the value check before any big wing.
The station keeps demand for the finished homes steady.
Fabric and ground handled
Lead paint joins asbestos on the pre-war fabric, licensed processes both, and the reactive pockets get engineered junctions.
Both the licensed strip-out and the junction work are in the fixed price.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Beverly Hills homes from the 1920s–1960s heritage Federation/Californian Bungalow + 1960s–1990s brick veneer + 2010s+ R3/R4 redevelopment around Hurstville/Kogarah/Beverly Hills CBDs 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.
⏱Quality Promise
Buildana's Beverly Hills home extension process: assess the existing structure, design the addition, approve, build. Fixed price throughout.
