Mascot Custom Home Builder — Local to the Job
Buildana builds custom homes in Mascot 2020 from our Fairfield office. We know Bayside Council's controls, the Class M soil, and the streets. Free consultation on your block.
Quick Answer
A custom home in Mascot 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.
Mascot Custom Home Construction
A custom home in Mascot is a rare thing, and honesty helps. Adjoining Sydney Airport, this is an R4-dominant precinct of apartment towers and former industrial conversions, so detached houses on the 300 to 600m² blocks are the exception, and a new detached build usually only stacks up where you hold one of those lots and want to keep it rather than sell into the towers.
Where a build is possible, three things shape it. Botany Sands means footings engineered for sand rather than a standard slab, the severe airport flight-path overlays make acoustic construction and glazing essential, and remediated industrial parcels can carry contamination histories worth checking before excavation. On the right block, R4 zoning is worth a feasibility check because a higher-density option may beat a single home.
What I would check first on your Mascot block: the sand-based footing design, the severe flight-path acoustic requirement, and any contamination history. Those set the path.
We build these fixed-price, licence HBL 487805C. Get our feasibility before you plan.
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.

Sand, noise and contamination

On the right block, R4 zoning is worth a feasibility check against a single home.

How It Works
From First Call to Final Key
We come to your Mascot site or you visit our office on The Horsley Drive in Fairfield. Either way, you leave the meeting with a clear cost band, an outline timeline, and a yes/no on whether your block supports the home you have in mind.
⏱Our designer draws up plans matched to your Mascot block — north-facing living, compliant setbacks, garage placement, and outdoor flow. You get floor plans, elevations, and 3D renders to review before we lock in the design.
⏱Documentation is where bad builders cut corners and good builds stay on track. Buildana commissions the borehole, instructs the engineer, prepares BASIX, and aligns hydraulic, structural, and architectural drawings before lodgement.
⏱CDC fast-track (10–15 business days) or DA through Bayside Council (40–90 days). Mascot is zoned R2 Low.
⏱Slab, frame, lock-up, fit-out, external works — all under fixed-price contract. Dedicated project manager on your build, weekly progress reports, and quality inspections at every critical hold point.
⏱OC, six-year structural warranty, two-year non-structural warranty, all manufacturer warranties on appliances and fixtures, BASIX certificate, certifier sign-offs, and maintenance schedule — all handed over in a single documentation pack. Keep it for your records and any future sale.
