A knockdown rebuild in Sandringham is a premium bayside play — a leafy, upmarket beachside enclave at the southern tip of Botany Bay, with inter-war and post-war stock on generous 500 to 900m² blocks and a direct beachfront premium. A rebuild designs a substantial modern home around a quiet bay-beach setting.
On the beachfront and near-beach blocks, coastal salt-grade specs apply. The Botany Sands soil shapes the footing design off a real geotech, and the R3 along the foreshore opens options on some blocks.
The older stock carries asbestos, so a licensed strip-out leads the demolition. The generous blocks here give a rebuild real design freedom.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the salt-grade specs and sands designed for, before you commit.
Buildana manages the complete knockdown rebuild process in Sandringham — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

A quiet, upmarket bay enclave
Sandringham sits at the southern tip of Botany Bay — leafy, quiet and upmarket, on generous 500 to 900m² blocks with a direct beachfront premium. A rebuild designs a substantial modern home around the bay-beach setting, with real design freedom on blocks this size.
It is one of the bayside's most tightly held enclaves.
Salt-grade specs and the sands
On the beachfront and near-beach blocks, coastal salt-grade specs apply — corrosion-resistant fixings and marine-suitable detailing. The Botany Sands soil shapes the footing design off a real geotech.
The older stock carries asbestos, so a licensed strip-out leads the demolition.
