A custom home in Coogee costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Randwick City Council approvals and fixed-price construction.
Custom Home Builder in Coogee
A custom home in Coogee is a beachside build where heritage, the coast and a tight lot all shape the design. This signature Randwick suburb runs Federation cottages, inter-war heritage and contemporary on 250 to 600m2 blocks fronting the beach, and Conservation Areas cover most of the older streets. At a $2.8M to $6M market a designed home on an eligible lot is a strong play, but on a contributory property the honest scope leans to restoration.
The ground is sandstone-dominant with substantial fall to the beach, so footings and any retaining are engineered to suit and rock is priced honestly. Coastal salt exposure means salt-grade detailing is mandatory. Some lots along Coogee Bay Road and Carrington Road carry R3, so density is worth checking there. On an eligible tight lot a considered design earns every square metre with orientation for light and outlook.
What I would check first on your Coogee block: the heritage status, any R3 potential on the main roads, and the sandstone fall and salt exposure. Those decide the job.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you whether it is a new build or a restoration.

How It Works
From First Call to Final Key
We start at the kerb. Before a single sketch, we stand on your Coogee block and work out what the land wants — sun path, slope, views, neighbours, the R2 Low envelope we've got to design inside. That walk determines almost every decision that follows.
⏱Design happens in layers. First the plan — where the kitchen is, how the bedrooms stack, what the morning routine looks like. Then the envelope — roof pitch, eave depth, window sizes matched to the Coogee climate. Then the finishes. Nothing gets drawn without a reason you can point to.
⏱Documentation is the unglamorous part, but it's where most projects go wrong. Engineering for Class M soil, BASIX 2025, Randwick City Council drawings, hydraulics, stormwater. We stage it so the certifier approves the first time — not the fourth.
⏱Then we build. Programme in hand, trades booked, material orders placed weeks before they're needed so nothing waits on delivery. Weekly update, monthly milestone walk, defects fixed as we go rather than collected at the end.
