A home extension in Enfield costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Burwood Council approvals, and construction under one fixed-price contract.
Second-Storey & Rear Additions in Enfield
A home extension in Enfield leans on some of the best structure in the inner west. This quiet residential suburb south of Burwood runs Federation cottages and Californian Bungalow homes, much of it solid brick that carries a first-floor addition on its original walls, alongside post-war stock that extends better at ground level. On 350 to 600m² R2 blocks, knowing which you own is the first question.
Heritage Conservation Areas run through several streets, so those frontages are examined while rear work usually passes without fuss. The strong school catchments are exactly why families stay and extend rather than move, and the quieter setting away from central Burwood holds its appeal. Where blocks are tight, a first floor on the bungalow stock adds bedrooms without touching the yard.
What I would check first on your Enfield house: whether the walls are bungalow-era brick or post-war, and any heritage pocket on the frontage. Those decide up or out.
We build these fixed-price, licence HBL 487805C. Book an inspection and we will read your walls.
Buildana manages the complete home extension process in Enfield — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Structure worth building on
This quiet suburb south of Burwood runs Federation cottages and Californian Bungalow homes, much of it solid brick that carries a first-floor addition on its original walls.
The post-war stock beside it extends better at ground level, so on the 350 to 600m² R2 blocks, knowing which you own is the first question.
Heritage and catchments
Several streets fall inside Heritage Conservation Areas, so the frontages get a close look while rear work generally goes through.
The strong school catchments are why families stay and extend rather than move, and a first floor on the bungalow stock adds bedrooms without touching a tight yard.

How It Works
From First Call to Final Key
Extension feasibility comes down to two things: what the existing structure can carry, and what Burwood 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 Enfield 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. Maintenance guide covers care of new and existing areas.
