A home extension in Milperra costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Canterbury-Bankstown Council approvals, and construction under one fixed-price contract.
Milperra Home Extensions & Additions
A home extension in Milperra suits a suburb built for extending. The 1960s to 1980s homes here sit on standard blocks with backyard depth, and at a $1.0M to $1.25M median a rear addition delivers the rooms a growing household needs for a fraction of what upsizing locally would cost. The quiet, established setting near the Georges River is exactly what owners want to keep.
The post-war stock extends best rearward. That era's framing suits ground-floor additions and resists second storeys without significant steel, so out is the standard call and the block depth makes it easy. Where older homes carry fibro, sheeting and eaves get a licensed asbestos strip-out before new work goes on. Panania station is a short hop, keeping the location practical.
What I would check first on your Milperra house: the frame type, any asbestos in older fibro, and the rear yard depth. Those set the scope.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Walk through your Milperra home with our designer and structural engineer. We measure, photograph, and check the bones — footings, frame condition, roof structure. The cost estimate that follows is grounded in what we found, not a generic per-m² number. 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.
⏱The Milperra construction phase. Fixed price, programmed, supervised. Most rear extensions in Milperra qualify for CDC — cleaner, faster, no neighbour notification. Second-storey additions typically need DA through Canterbury-Bankstown Council because of overshadowing and privacy assessments. We choose based on your design, not on what's easier to lodge. Extension built from new footings to completion — connecting structurally to your existing home. Class M soil design managed. Temporary weatherproofing maintains liveability where possible.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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. Maintenance guide provided.
⏱Quality Promise
Our Milperra home extensions connect old-to-new cleanly. Matched brickwork, tied roofline, no awkward transitions.
