A custom home in Oxford Falls costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Northern Beaches Council approvals and fixed-price construction.
Oxford Falls Custom Home Construction
A custom home in Oxford Falls is a premium rural-residential acreage build with some of the most demanding site controls on the Northern Beaches. These are 1 to 5 hectare-plus RU2 holdings with bushland and a strong horse-property tradition, and at a $3M to $6M-plus acreage market a designed homestead is a serious, long-term build. The land and the seclusion are the point, and the constraints are real.
Bushfire ratings are universal, from BAL-29 up to Flame Zone, so an RFS Bushfire Protection Assessment is mandatory and drives the spec. This is Hawkesbury Sandstone with deep rock at $80K to $200K-plus, there is no reticulated sewer so an AWTS on-site system is mandatory, and siting the homestead weighs access, bushfire, outlook and the equestrian use all at once.
What I would check first on your Oxford Falls property: the BAL rating and bushfire spec, the deep rock, and the AWTS wastewater and siting. Those set the home.
We build these fixed-price, licence HBL 487805C. Show us the property and we will design the home and its siting together.
Buildana's design-and-construct service covers everything — from initial design brief and land assessment through to council approval and fixed-price construction. One builder, one contract, one point of contact.

How It Works
From First Call to Final Key
Book a free consultation at our Western Sydney showroom or on your Oxford Falls block. We assess the site, walk through your brief, and outline a realistic budget and timeline. No obligation, no sales pressure.
⏱We design for Oxford Falls's climate and your 1–5ha+ acreage (RU2) block: cross-ventilation, eaves sized for summer sun angles, living rooms positioned for winter light. Functional first, then we work on the aesthetic. Material palette and finishes locked in alongside the plan, not as an afterthought.
⏱Full documentation pack: structural engineering for Class Hawkesbury Sandstone soil, BASIX Certificate, geotechnical testing, stormwater design, and all drawings Northern Beaches Council and your certifier need. Nothing left to chance.
⏱Approval pathway gets chosen at design stage, not after. CDC is faster but constrains the design envelope; DA gives flexibility but adds time. Buildana flags the trade-off early so you decide which side of that line you want to be on for your Oxford Falls build.
⏱Fixed-price build from engineered slab to keys. Weekly milestone updates from your dedicated project manager. Quality inspections at every stage.
⏱Defect-free handover inspection with you on site. Occupation Certificate, 6-year structural warranty, appliance manuals, maintenance schedule, and the keys to your new Oxford Falls home.
