A home extension in Dolls Point is built around the water. This little beachside enclave sits on generous 500 to 800m² blocks, and the premium is entirely in the bay outlook — so the wing faces it directly, glazed to the view and built in salt-grade materials that survive the foreshore air.
The waterfront position rewards designs that make the most of it, the reclaimed sands are read before excavation, and the era fabric gets licensed handling where we open it.
At a $2.0M to $3.5M median the wing beats trading out of an enclave this tightly held.
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 Dolls 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.

Everything faces the bay
The waterfront premium rewards a wing built around the outlook — living opened to the water, generous glazing, alfresco that uses it — on blocks with genuine room to do it properly.
The quiet enclave character holds every metre you add.
Sands and salt handled
The reclaimed sands are read before any excavation-touching work, and the footings are engineered to suit.
Salt-grade fixings are standard this close to the foreshore, and the older fabric comes out under licence — priced in up front.

How It Works
From First Call to Final Key
Walk through your Dolls Point home with our designer and structural engineer. We measure, photograph, and check the bones — footings, frame condition, roof structure. The cost estimate that follows is grounded in what we found, not a generic per-m² number.
⏱Our designer works with your existing home's layout — connecting new living areas to existing rooms, matching materials and roof pitch, and maximising natural light. You approve floor plans and 3D renders before we proceed.
⏱Most rear extensions in Dolls Point qualify for CDC — cleaner, faster, no neighbour notification. Second-storey additions typically need DA through Bayside Council because of overshadowing and privacy assessments. We choose based on your design, not on what's easier to lodge.
⏱Extension built from new footings to completion — connecting structurally to your existing home. Class M soil design managed. Temporary weatherproofing maintains liveability where possible.
⏱Walk through the completed extension, confirm finishes, collect your OC. Six-year structural warranty covers all new work including the junction with your existing home. Maintenance guide provided.
