Licensed Knockdown Rebuild Builder Kenthurst
NSW licensed KDR specialist in Kenthurst 2156. Asbestos-accredited demolition, Class M engineered slab, BASIX 2025, 6-year structural warranty on the new home.
Demolish and Rebuild in Kenthurst
A knockdown rebuild in Kenthurst is a premium acreage project — one to ten-plus hectare RU2 holdings on Hawkesbury Sandstone, in equestrian and lifestyle territory with a genuine premium character. A rebuild delivers a substantial rural-residential home on a serious holding.
The acreage path applies in full: RU2 rural provisions, significant bushfire-prone overlays shaping the design to its BAL rating, on-site wastewater, and sandstone that can mean serious rock, priced from a real geotech bore.
There is no rail out here — you are buying the land, the trees and the privacy. I plan the rebuild as acreage from the start.
We rebuild fixed-price, licence HBL 487805C. Get our acreage feasibility before you commit.
Buildana manages the complete knockdown rebuild process in Kenthurst — 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.

Premium acreage, planned properly
Kenthurst's one to ten-plus hectare RU2 holdings are premium equestrian and lifestyle land, and a rebuild here delivers a substantial home that suits the holding. The rural planning path — provisions, access, setbacks — applies in full.
There is no rail; the land, trees and privacy are the point, and the build should match them.
Bushfire, wastewater and rock
The bushfire-prone overlays are significant, so the design meets its BAL rating from the RFS assessment. On-site wastewater is designed for the holding, and the Hawkesbury Sandstone can mean serious rock, priced from a real geotech bore.
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 M 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 Kenthurst 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 M soil) to keys — fixed-price, milestone-based progress payments. Your project manager provides weekly updates.
⏱Walk through your finished home on your original Kenthurst block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule.
