A home extension in Tempe costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Inner West Council approvals, and construction under one fixed-price contract.
Second-Storey & Rear Additions in Tempe
A home extension in Tempe works with terraces, tight ground and a suburb wedged between the Cooks River and the motorway. The Victorian terraces, Federation cottages and post-war stock on 200 to 500m² blocks sit in heritage conservation pockets that watch the frontages, so the work goes to the rear, opening narrow floor plans into usable kitchen-living space. At a $1.6M to $2.4M median a metre from the river, the space is worth making.
Two local checks matter. Alluvial pockets near the Cooks River need proper footing design before new load goes on, and the airport flight-path proximity makes acoustic glazing on new rooms a sensible inclusion. Party walls and tight access set the method on the terraces, with materials through the house where side access does not exist. The WestConnex corridor defines the western edge.
What I would check first on your Tempe house: the heritage pocket status, the alluvial footings if you are near the river, and the acoustic requirement. Those set the scope.

Rear work by the river
The Victorian terraces, Federation cottages and post-war stock on 200 to 500m² blocks sit in heritage conservation pockets that watch the frontages, so the work goes to the rear.
That opens narrow floor plans into usable kitchen-living space, and at a $1.6M to $2.4M median a metre from the Cooks River, the space is worth making.
Alluvial ground and flight path
Alluvial pockets near the Cooks River need proper footing design before new load goes on, and the airport flight-path proximity makes acoustic glazing on new rooms sensible.
Party walls and tight access set the method on the terraces, with materials carried through the house where side access does not exist.

How It Works
From First Call to Final Key
On-site assessment of your 1900s–1950s-era home in Tempe. We check structural condition, block dimensions (200–500m²), setback availability, and Inner West 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.
⏱We lodge your extension approval — CDC for eligible designs or DA through Inner West 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.
⏱Final inspection, Occupation Certificate, 6-year structural warranty. Your Tempe home now has the space your family needs.
