New Home on Your Oxford Falls Block
A knockdown rebuild in Oxford Falls is a premium acreage project with a horse-property tradition — RU2 holdings of one to five-plus hectares with bushland and equestrian character. A rebuild delivers a substantial rural homestead on serious land close to the beaches.
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, and mandatory AWTS on-site sewer.
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 Oxford Falls — 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.

Equestrian acreage near the beaches
Oxford Falls' one to five-plus hectare RU2 holdings carry a genuine horse-property tradition, with bushland character and the beaches close. A rebuild delivers a substantial rural homestead that suits the holding — stables, arenas and all — planned as acreage from the start.
It is a rare combination: rural land within minutes of the coast.
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, and AWTS on-site sewer is mandatory.
All of it is in the feasibility and the fixed price before we start.

How It Works
From First Call to Final Key
KDR starts with an honest look at the existing house. Sometimes it's worth keeping. Most Oxford Falls homes from the 1970s–1990s rural + premium contemporary homesteads — especially fibro and brick-veneer — are beyond the point where renovation makes sense. We tell you straight.
⏱Demolition is pre-approved to run parallel with rebuild design. Asbestos cleared, services abolished, site stripped in a single mobilisation. Geotech reconfirms Class Hawkesbury Sandstone soil with the old house gone.
⏱New house goes up on the same footprint or a better one, whichever serves the block. Modern NCC envelope, better orientation, fit-for-purpose room sizes. The suburb stays the same; the house finally fits it.
⏱Final handover: new OC, six-year structural warranty, all the documentation on your Oxford Falls block you'd get on a greenfield build. The only difference is you still live in the street you chose.
⏱Quality Promise
Oxford Falls KDR projects run on one contract: demolition, asbestos clearance, approvals, construction, handover. One builder accountable.
