Building Custom Homes in Greenwich
A custom home builder in Greenwich is back on sandstone and the harbour fall. This peninsula between Greenwich Point, Manns Point and Bay Road holds Federation mansions and inter-war homes on generous 500 to 1,200m² blocks, many falling to the water with direct harbour outlook. Heritage Conservation Areas cover most streets, so the first question is always what your address allows.
The build is a harbour-fall project: sandstone excavation, retaining, and a design that steps down the block to reach the water. Where a home is contributory heritage it stays and gets reworked; where it is not, a new home is possible if it answers the street. The Greenwich ferry and the quiet, leafy foreshore character are the draw, with Wollstonecraft station about 1.5 km out.
What I would check first on a Greenwich block: the heritage status, how far it falls to the harbour, and the depth of the rock. Those three set the envelope and the budget before design.
We build these to standard, fixed-price, licence HBL 487805C. Send us the address for an honest read on the heritage, the fall and the rock.
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.

A harbour-fall build on generous blocks
Greenwich gives you two things at once: size and a harbour fall. At 500 to 1,200m² there is room for a substantial home, and on the streets that drop to the water the design gets to step down the block and open to the outlook. That fall is the opportunity and the cost, both together.
Working it means sandstone excavation, retaining and a considered section. Done well, the house reaches the water on every main level. We walk the fall and get the rock investigated before quoting, because a Greenwich number off a plan is a guess.
Heritage decides rebuild or rework
Most Greenwich streets sit in Conservation Areas, so whether you can rebuild or must rework behind a retained frontage comes down to your exact address. We check the heritage status first and design new work that holds its own on a street of Federation mansions.
Send us the address and we will read the heritage, the fall and the rock together and tell you what the block can carry and what a home of this kind costs here.

How It Works
From First Call to Final Key
We start at the kerb. Before a single sketch, we stand on your Greenwich block and work out what the land wants — sun path, slope, views, neighbours, the R2 Low Density 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 Greenwich 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, Lane Cove 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.
⏱Quality Promise
Every Buildana custom home in Greenwich is designed for your block and built under a fixed-price contract — no surprises, no hidden extras.
