Knockdown Rebuild Builder in Terrey Hills
A knockdown rebuild in Terrey Hills is a premium acreage project — RU2 holdings of one to five-plus hectares with equestrian and horticultural character, on the plateau between the beaches and the upper North Shore. A rebuild delivers a substantial rural homestead on serious land.
The acreage stack applies in full: BAL-29 to Flame Zone universal with the RFS assessment mandatory, deep sandstone rock of $80,000 to $200,000-plus priced from a geotech bore, mandatory AWTS on-site sewer, and the Drinking Water Catchment overlay on the western edge.
The older rural homes can carry asbestos, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our acreage feasibility, with the full stack costed, before you commit.
Buildana manages the complete knockdown rebuild process in Terrey Hills — 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.

Plateau acreage, planned properly
Terrey Hills' one to five-plus hectare RU2 holdings sit on the plateau between the beaches and the upper North Shore, with genuine equestrian and horticultural character. A rebuild delivers a substantial rural homestead that suits the holding, planned as acreage from the start.
The location — rural land minutes from both St Ives and the beaches — is the draw.
The full acreage stack
BAL-29 to Flame Zone is universal with the RFS assessment mandatory, the sandstone means deep rock of $80,000 to $200,000-plus priced from a geotech bore, AWTS on-site sewer is mandatory, and the catchment overlay touches the western edge.
All of it is in the feasibility and the fixed price before we start.

How It Works
From First Call to Final Key
Site visit covers everything that affects the build cost: vehicle access for trucks and crane, services (sewer depth, water connection, electrical service rating), soil exposure for borehole, neighbouring construction, and any obvious heritage or tree constraints. Real numbers, not estimates.
⏱Architectural design for your replacement home, structural engineering for Class Hawkesbury Sandstone soil, BASIX certification, and all approval documentation. Lodged as CDC (10–15 days) or DA (40–90 days) depending on design.
⏱Demolition runs 5–10 working days for a standard Terrey Hills cottage — longer if asbestos volume is significant or the structure includes a brick chimney or solid-block walls. Asbestos work happens first under a controlled removal program before mechanical demo starts.
⏱New home built from engineered slab (Class Hawkesbury Sandstone soil) to keys — fixed-price, milestone-based progress payments. Your project manager provides weekly updates.
⏱Walk through your finished home on your original Terrey Hills block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule.
