Building Custom Homes in Box Hill
A custom home in Box Hill is a build-on-your-lot in the North-West Growth Centre, where the land is new and the design is yours to set. This master-planned release suburb runs 2015-plus contemporary homes on 300 to 600m2 lots, and at a $1.1M to $1.6M new-release market a designed home lets you step past the volume-builder template on the estate around you. Getting in early with a considered design pays off as the area matures.
The lots range from compact to mid-sized, so a double-storey design captures the floor area a family needs while keeping a usable yard. This is Wianamatta Shale ground, so footings get stable, predictable bearing and a slab off geotech is routine, though the rural fringe carries bushfire exposure worth checking on the edge lots. On a new registered lot the pathway is clean, with estate controls the main thing to answer.
What I would check first on your Box Hill lot: the estate design controls, any bushfire exposure on fringe lots, and the double-storey design for the block. Those set the home.
We build these fixed-price, licence HBL 487805C. Bring us your lot and brief and we will draw it.
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 Box Hill block. We assess the site, walk through your brief, and outline a realistic budget and timeline.
⏱We design for Box Hill's climate and your 300–600m² (new release) block: cross-ventilation, eaves sized for summer sun angles, living rooms positioned for winter light. Functional first, then we work on the aesthetic.
⏱Full documentation pack: structural engineering for Class M soil, BASIX Certificate, geotechnical testing, stormwater design, and all drawings The Hills Shire 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.
⏱Fixed-price build from engineered slab to keys. Weekly milestone updates from your dedicated project manager.
⏱Defect-free handover inspection with you on site. Occupation Certificate, 6-year structural warranty, appliance manuals, maintenance schedule, and the keys to your new Box Hill home.
