A custom home in Sylvania costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Sutherland Shire Council approvals and fixed-price construction.
Custom Home Builder in Sylvania
A custom home in Sylvania is a family build in the residential corridor between Miranda and Sylvania Waters, where sandstone shapes the substructure. The streets run 1970s to 1990s brick veneer on 550 to 750m2 R2 blocks, and at a $1.6M to $2.4M market a designed replacement is a strong family play close to Westfield Miranda. The convenient location and the generous blocks are the draw.
This is Hawkesbury Sandstone bedrock, so rock-cutting is common on the substructure scope and is assessed and priced honestly up front. The blocks open single or double-storey family designs with a real backyard, and there are no broad heritage overlays, which keeps the approval path predictable. Where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your Sylvania block: the rock and substructure, the building envelope, and any asbestos in older stock. Those set the home.
We build these fixed-price, licence HBL 487805C. Bring us your block 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 Sylvania block. We assess the site, walk through your brief, and outline a realistic budget and timeline.
⏱We design for Sylvania's climate and your 550–800m² typical; 600–1,000m² premium beachside/foreshore (Cronulla/Burraneer/Lilli Pilli/Yowie Bay/Caringbah South/Sylvania Waters); 700–2,000m² bushland-fringe (Bundeena, Maianbar, Bangor, Menai) 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 Hawkesbury Sandstone bedrock soil, BASIX Certificate, geotechnical testing, stormwater design, and all drawings Sutherland 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 Sylvania home.
