A custom home in Randwick 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.
Randwick Home Builds — Made to Your Brief
Between the racecourse, the hospital and the light rail, Randwick land works hard, and a custom home here has to work harder. Blocks run 250 to 600m² with Federation cottages and inter-war housing, and Heritage Conservation Areas cover several streets including the village core around Randwick Junction, so the buildable sites split cleanly. Protected stock you work with, and clear lots you build fresh on. Medians of $2.5M to $5M do not leave room for guessing which is which.
The clear sites reward tight, two-storey design that wins light on a narrow footprint, and sandstone underneath keeps foundations solid while it does. Prince of Wales Hospital anchors professional demand, the light rail runs in-suburb, and Coogee is down the hill. Verify heritage status before you exchange, not after. It is a one-day check that saves a six-figure mistake.
What I would check first on a Randwick block: whether it is heritage-protected or a clear lot, the sandstone for foundations, and how a two-storey plan wins light on the footprint. Those set the project.
We build these to standard, fixed-price, licence HBL 487805C. We will run the heritage check for you.
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.

Heritage-bound or build-ready
Randwick's buildable sites split cleanly in two. Heritage Conservation Areas cover several streets, including the village core around Randwick Junction, so some blocks are protected stock you work with and others are clear lots you build fresh on.
At a $2.5M to $5M median there is no room to guess which is which. Verifying heritage status before you exchange is a one-day check that saves a six-figure mistake.
Tight two-storey design on solid ground
On the clear sites, the design rewards tight, two-storey architecture that wins light on a narrow 250 to 600m² footprint, and sandstone underneath keeps the foundations solid while it does.
Prince of Wales Hospital anchors professional demand, the light rail runs in-suburb, and Coogee is down the hill. Send us the address and we will run the heritage check before you exchange.

How It Works
From First Call to Final Key
We start with a site visit or showroom meeting to talk through what you want to build on your Randwick block. We'll review Randwick City Council's planning controls for 250–600m² lots with R2 Low zoning and give you a straight answer on budget and feasibility.
⏱Design starts with site analysis — sun path, prevailing breeze, neighbour overlooking, slope, view lines from each likely living area. The plan is drawn to that, not dropped onto the block. Two design options usually, sometimes three, then you pick the direction and we refine.
⏱Working drawings, structural engineering (Class M soil design), BASIX certification, geotechnical report, stormwater plan and all certification documentation prepared.
⏱Most custom homes in Randwick qualify for CDC with a 10–15 business day turnaround. If DA is required through Randwick City Council, we manage the full submission and respond to any requests for information. Construction Certificate follows.
⏱Construction is run from a programme, not made up week to week. Trade sequencing is locked in advance so the slab cures into a waiting frame and the frame waits for nothing. That's how a 24–40 week build actually delivers in 24–40 weeks instead of running 60+.
⏱Walk through your finished home, collect keys, and move in. OC issued, defect-free inspection completed, 6-year structural warranty, and full maintenance guide provided.
