A home extension in Cabarita has room to be generous, because the blocks are — Federation and inter-war homes on 500 to 1,000m² on the peninsula toward the river and the park. That much land lets a wing open the living out to the water and the greenery with proper alfresco, rather than squeezing a room onto the back.
The era read decides the approach on the older stock, and where the blocks drop toward the water the fall is engineered. Pre-war fabric gets its lead paint and asbestos handled under licence wherever the work touches it.
At a $2.5M to $5M median, a wing that opens to the river setting is the natural play — the ferry-side, park-side peninsula lifestyle is the asset, and the block sizes here let you build to it without compromise.
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 Cabarita — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Room by the river
Cabarita's 500 to 1,000m² blocks give a wing genuine room — living opened toward the river and the park, generous alfresco, and the ferry-side lifestyle still intact afterwards.
The era read decides the approach on the Federation and inter-war stock.
Fall and fabric handled
The fall is engineered where the blocks slope toward the water.
Lead paint sits with the asbestos in the pre-war fabric, both removed under licence and costed into the riverside job upfront.

How It Works
From First Call to Final Key
Extension feasibility comes down to two things: what the existing structure can carry, and what City of Canada Bay 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 Cabarita 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–H 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.
