A home extension in Kurraba Point is a harbour project first and a building project second. This premium peninsula between Neutral Bay and Shell Cove falls hard to the water, and the Federation and inter-war homes on 300 to 600m² blocks sit where a well-placed upper level can claim a harbour outlook worth a serious premium in a $3.2M to $6.5M market. The slope and the heritage set every term of the job.
Heritage controls here are heavy, so street-facing changes get examined closely while rear and set-back upper work moves more freely. The ground is sandstone with substantial harbour fall, so engineered slabs and retaining are standard rather than optional, and excavation is a test-dig conversation. Small blocks mean the design has to be precise, with every square metre earning its place.
What I would check first on your Kurraba Point block: the heritage status, the harbour fall and how the addition sits on it, and the sandstone in the dig. Those decide the design and budget.
We build these fixed-price, licence HBL 487805C. Send us your fall and we will design to it.
Buildana manages the complete home extension process in Kurraba Point — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

A harbour project
This premium peninsula falls hard to the water, and the Federation and inter-war homes on 300 to 600m² blocks sit where a well-placed upper level can claim a harbour outlook worth a serious premium in a $3.2M to $6.5M market.
The slope and the heritage dictate every term of the job.
Heavy heritage, steep ground
Heritage controls are heavy, so street-facing changes get examined while rear and set-back upper work moves more freely.
The sandstone ground with substantial harbour fall makes engineered slabs and retaining standard rather than optional, and small blocks mean the design has to be precise.

How It Works
From First Call to Final Key
Extension feasibility comes down to two things: what the existing structure can carry, and what North Sydney 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 Kurraba Point 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.
