Quick Answer
A custom home in Lewisham costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Inner West Council approvals and fixed-price construction.
Lewisham Custom Home Construction
A custom home in Lewisham is usually a restoration or a rear extension, not a new build, because Conservation Areas cover much of this small terrace suburb. The Victorian terraces and Federation cottages sit on 150 to 400m2 blocks, and on a contributory property the honest answer is to restore the front and rework the rear. A full knockdown is precluded across most of the suburb, and I would rather be straight about that up front.
This is Wianamatta Shale, so any approved works are engineered to suit, and the challenge on these tight blocks is winning light and space at the rear within the heritage envelope. R4 applies around the station, so a lot there may sit in a different use category. Where a genuinely non-contributory or infill site exists, a sympathetic new home is possible, but it is uncommon.
What I would check first in Lewisham: the heritage status of the terrace, whether any new build is permissible, and the rear envelope for light and space. That decides the scope.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you honestly whether it is a restoration, an extension or a rare new build.
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 Lewisham block and work out what the land wants — sun path, slope, views, neighbours, the R1/R2 General/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 Lewisham 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, Inner West 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.
