Licensed Custom Home Builder North Wahroonga — Design & Construct
NSW licensed builder (Oliver Alameri) delivering fixed-price custom homes across North Wahroonga 2076. Engineered slab for Class M soil, BASIX 2025, 6-year structural warranty.
Quick Answer
A custom home in North Wahroonga costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Ku-ring-gai Council approvals and fixed-price construction.
Building Custom Homes in North Wahroonga
The per-square-metre land price in North Wahroonga undercuts every rail suburb around it, and the blocks are twice the size. That is the custom home pitch in one line. 1,000 to 2,000m² bush-edge lots of 1950s to 1970s housing at $2.4M to $3.4M, in a Ku-ring-gai pocket where the 1,200m² duplex minimum means nobody is splitting the land around you. No station of its own, buses run to Wahroonga and Hornsby, which is exactly why the value exists.
Blocks this size change what you can design. Single-level living, a genuine garden, a pool that is not wedged against a fence, room for the house to breathe. The eastern fringe carries bushfire planning rules where the reserves press in, so BAL assessment comes early on those streets. Post-war stock at this age is replacement stock.
What I would check first on a North Wahroonga block: the BAL rating on the reserve fringe, how the big block is best used, and the age of the existing house. Those set the design.
We build these to last, fixed-price, licence HBL 487805C. If you want land over convenience, this is your suburb, so come talk.
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.

Land over convenience
North Wahroonga's pitch is one line: the per-square-metre land price undercuts every rail suburb around it, and the blocks are twice the size. 1,000 to 2,000m² bush-edge lots at $2.4M to $3.4M, in a Ku-ring-gai pocket where the 1,200m² duplex minimum means nobody splits the land around you.
It has no station of its own, buses run to Wahroonga and Hornsby, and that trade of convenience for space is exactly why the value exists.
Room for the house to breathe
Blocks this size change what you can design: single-level living, a genuine garden, a pool that is not wedged against a fence, room for the house to breathe. Post-war stock at this age is replacement stock, so a rebuild is the natural move.
The eastern fringe carries bushfire planning rules where the reserves press in, so BAL assessment comes early on those streets. Send us the address and we will read the BAL and the block together.

How It Works
From First Call to Final Key
We start at the kerb. Before a single sketch, we stand on your North Wahroonga 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 North Wahroonga 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, Ku-ring-gai 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
North Wahroonga custom home construction done properly: design tailored to your block, compliance handled, pricing locked in before we start.
