Extending Homes in East Hills
A home extension in East Hills should be designed toward the green. The suburb's whole appeal is the leafy, river-side setting on generous blocks, and too many of these homes turn their backs on it — so the wing that works here is the one that opens the living and alfresco out to the gardens and the reserve, rather than just adding floor area for its own sake.
There is one thing to get right early. On the blocks closer to the Georges River, the flood mapping sets your floor levels, so I check that before a design is committed rather than after. The 1960s to 1980s brick takes the wing cleanly, and any older fibro that surfaces is stripped out under licence.
At a $1.1M to $1.35M median with the station close by, staying and building is the clear call. The setting is the reason you would never want to leave, and the extension is built to make more of it.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the flood mapping checked, before you commit.
Buildana manages the complete home extension process in East 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.

Face the wing at the green
The leafy character is East Hills' real asset, so the extension is built to serve it — living and alfresco turned toward the garden and the reserve, on blocks with genuine room to work.
The station keeps daily family life practical right through the build.
Flood edge and fabric handled
On the river-side blocks the flood mapping is checked before floor levels are set, so nothing has to be redrawn late.
Any older fibro is stripped out under licence, and both that and the flood work are inside the fixed price from the outset.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. On-site assessment of your 1960s–1980s-era home in East Hills. We check structural condition, block dimensions (500–700m²), setback availability, and Canterbury-Bankstown Council's DCP requirements. Written feasibility and cost estimate provided. Designing an extension is half about the new space and half about how it joins the old one. Doorway position, ceiling height transition, floor level matching, light wells — the junction makes or breaks how the finished home feels.
⏱The East Hills construction phase. Fixed price, programmed, supervised. We lodge your extension approval — CDC for eligible designs or DA through Canterbury-Bankstown Council. Full documentation including structural engineering for Class M soil, BASIX, and shadow diagrams. CC issued before works start. For ground-floor rear extensions you usually stay in the house during the build, with temporary weatherproofing at the junction wall until the new section is locked up. Second-storey additions need a 4–8 week relocation during the roof-off and frame-up phase.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection, Occupation Certificate, 6-year structural warranty. Your East Hills home now has the space your family needs.
⏱Quality Promise
Every Buildana home extension in East Hills is delivered under a fixed-price contract — from design consultation through to defect-free handover.
