A custom home in Kensington 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.
Kensington Home Builds — Made to Your Brief
A custom home in Kensington is a build shaped by heritage, zoning and the UNSW campus next door. The streets run Federation cottages, inter-war heritage and post-war flats on 250 to 600m2 blocks, with R3 and R4 along Anzac Parade and Doncaster Avenue, and at a $2.2M to $4M market a designed home on an eligible lot is a strong eastern play. What the land carries depends on the specific address.
Heritage Conservation Areas cover several streets, so the status check comes first, and where a lot sits along the R4 corridor the highest use may be well beyond a single home. The ground is engineered off geotech to suit, and on an eligible tight lot a considered double-storey design earns every square metre. The light rail and UNSW drive steady demand across the suburb.
What I would check first on your Kensington block: the heritage status and zoning, whether density beats a single home, and the tight-lot envelope. Those set what is possible.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you what the block allows.
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
We start at the kerb. Before a single sketch, we stand on your Kensington 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 Kensington 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.
