A custom home in Fairfield costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Fairfield City Council approvals and fixed-price construction.
Custom Homes Designed for Fairfield
A custom home in Fairfield is close to home for us, because this is Buildana's base, and we know the ground and the council here as well as anyone. The suburb runs 1950s to 1980s stock on wide 450 to 700m2 blocks with strong R2 and R3 zoning, and at a $950K to $1.2M median a designed replacement is a sound family move, with a duplex worth checking on the larger lots. Local knowledge counts for a lot on these blocks.
The ground runs Class M to H, so footings are engineered off geotech to suit and the slab is detailed for movement where the clay is reactive. The wide blocks open single or double-storey family designs with a real backyard, and where a lot clears the 600m2 dual-occupancy minimum a duplex is worth weighing against a single home. Where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your Fairfield block: the M to H footing design, whether a duplex beats a single home, and any asbestos in older stock. Those set the direction.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you the best use of 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
Everything that has to be right before we touch the ground. Free initial consultation — we discuss your Fairfield build, your brief, your budget, and your block. Fairfield blocks are typically 450–700m² with R2 Low Density & R3 Medium Density zoning. Honest advice on what's achievable under Fairfield City Council's controls. Design phase covers layout, orientation, and aesthetics for your Fairfield site. We work through room sizes, ceiling heights, storage, and natural light until the plan fits how your family actually lives. 3D renders show the finished result before construction starts.
⏱The Fairfield construction phase. Fixed price, programmed, supervised. Construction-grade drawings, not concept sketches. Class M–H engineered slab and footings, structural frame computations, BASIX 2025 compliance, stormwater connection design, contour survey, and detailed sections through every junction. Approval pack ready for Fairfield City Council or private certifier. We lodge and manage your approval — CDC for eligible designs (10–15 business days) or DA through Fairfield City Council if the design sits outside complying development thresholds. CC issued before construction starts. Build sequence on your Fairfield block: site set-up, slab pour and cure, frame stand and tie-down, roof and lock-up, internal fit-out (plaster, paint, joinery, tiles), kitchen and bathroom installation, final services connection, external works (driveway, fencing, landscaping). Each stage signed off before the next.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection, Occupation Certificate, 6-year structural warranty, keys, and maintenance guide. Your new home near Fairfield Forum & The Horsley Drive commercial strip.
⏱Quality Promise
Our Fairfield custom home builds run on a single contract from brief to keys. Fixed price. No variations unless you change the design.
