A home extension in Roselands leans on convenience. The 1940s to 1970s homes sit on 500 to 700m² blocks close to the centre, and being minutes from the shopping and transport is a big part of why people would rather grow the house than move away from it. A rear wing adds the room while the everyday stuff stays on the doorstep.
Whether the wing is the right call depends on the house. Solid brick takes it well; a tired fibro home gets a rebuild comparison instead of a wing propped on a failing shell. Any fibro uncovered in the work is stripped out under licence before framing, and the footings are engineered to your ground.
At a $1.1M to $1.35M median the sums for staying stack up when the bones are worth it. The amenity that makes Roselands easy to live in is exactly what you keep by building rather than selling.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.
Buildana manages the complete home extension process in Roselands — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Convenience worth keeping
Being close to the shopping centre and transport keeps daily life easy in Roselands, and a rear wing adds the bedrooms and second living space while all of that stays minutes away.
I read the house before designing, so the budget goes where it returns rather than into propping up a shell that has had enough.
Fibro and footings, sorted early
Fibro the work uncovers is pulled out under a licensed strip-out before any framing goes back.
The footings are engineered to the ground under your slab, and both jobs are inside the fixed price from the outset.

How It Works
From First Call to Final Key
Extension feasibility comes down to two things: what the existing structure can carry, and what Canterbury-Bankstown Council will let you build. We assess both at the consultation — no point designing for a second storey if the slab can't take the load.
⏱Extension designed to integrate with your existing Roselands home — matching roof lines, materials, and flow between old and new sections. Floor plans, elevations, and 3D renders.
⏱All approval documentation prepared: structural drawings, BASIX, shadow analysis, stormwater, and statement of environmental effects (if DA). Lodged and managed through to Construction Certificate.
⏱Extension construction takes 3–6 months on average. Footings excavated and poured to match existing depth on Class M soil, frame stand, roof tie-in (most weather-critical phase), lock-up, then internal fit-out at the same standard as the existing house.
⏱Defect-free inspection, OC issued, 6-year warranty on all new work. Junction between old and new sections waterproofed and warranted.
