A home extension in Bradbury costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Campbelltown City Council approvals, and construction under one fixed-price contract.
Second-Storey & Rear Additions in Bradbury
A home extension in Bradbury puts moving money into rooms — 1970s-1990s brick veneer on 500 to 800m² blocks at an $850K to $1.1M entry, where the rear wing shifts the home meaningfully.
Clay junctions get engineered, the older fabric is handled under licence, and the generous blocks leave real room to work.
The stamp duty of upsizing locally would fund a good part of the addition.
We build these fixed-price, licence HBL 487805C. Walk us through it before you talk to an agent.
Buildana manages the complete home extension process in Bradbury — 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 staying maths
At Bradbury's entry, trading up locally costs more in friction than a rear wing — so the addition keeps the money in the building.
The generous blocks leave real room to add the living and bedrooms.
Junctions and era handled
Reactive clay means engineered junctions, and the older fabric gets licensed handling wherever it's disturbed.
Both sit in the fixed price up front, before a hammer swings.

How It Works
From First Call to Final Key
Walk through your Bradbury home with our designer and structural engineer. We measure, photograph, and check the bones — footings, frame condition, roof structure.
⏱Our designer works with your existing home's layout — connecting new living areas to existing rooms, matching materials and roof pitch, and maximising natural light. You approve floor plans and 3D renders before we proceed.
⏱Most rear extensions in Bradbury qualify for CDC — cleaner, faster, no neighbour notification. Second-storey additions typically need DA through Campbelltown City Council because of overshadowing and privacy assessments.
⏱Extension built from new footings to completion — connecting structurally to your existing home. Class M soil design managed.
⏱Walk through the completed extension, confirm finishes, collect your OC. Six-year structural warranty covers all new work including the junction with your existing home.
