A custom home in Sans Souci costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Bayside Council approvals and fixed-price construction.
Sans Souci Custom Home Construction
A custom home in Sans Souci is a premium peninsula build between the Georges River and Botany Bay, where mixed ground and salt shape the spec. The streets run inter-war heritage, post-war brick and contemporary on 500 to 900m2 blocks, and at a $2.0M to $4M market, and more on waterfront, a designed home oriented to the water is a strong play. The direct waterfront premium on both the river and the bay is the draw.
This is the Botany Sands and Wianamatta Shale interface, so footings are engineered off geotech to suit the specific lot, since the ground varies across the peninsula. Coastal salt exposure drives salt-grade detailing on waterfront lots, and R3 along Rocky Point Road means a well-placed lot is worth a density check. On a waterfront block a design oriented to the water makes the most of the position.
What I would check first on your Sans Souci block: the sand-versus-shale footing design, the salt-grade detailing on the waterfront, and any R3 potential on Rocky Point Road. Those set the home.
We build these fixed-price, licence HBL 487805C. Show us your block and outlook and we will design to 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 Sans Souci block. We assess the site, walk through your brief, and outline a realistic budget and timeline.
⏱We design for Sans Souci's climate and your 500–900m² 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 Bayside 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 Sans Souci home.
