A custom home in Killarney Heights costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Northern Beaches Council approvals and fixed-price construction.
Custom Homes Designed for Killarney Heights
A custom home in Killarney Heights is an established bushland-fringe build where sandstone and any BAL rating shape the spec. The suburb runs 1960s to 1980s brick on 600 to 900m2 blocks with sandstone topography, and at a $2.2M to $3.4M market a designed replacement is a strong family play in a green, settled setting. Garigal National Park and the Castlecrag fall frame the suburb.
This is Hawkesbury Sandstone, so rock excavation runs $40K to $120K on many sites and is assessed and priced honestly up front. Bushland-fringe lots backing Garigal carry a BAL rating from 12.5 up to 29, so the construction spec answers the bushfire risk where it applies. The generous blocks open single or double-storey family designs, and a home oriented to the bush makes the most of the position.
What I would check first on your Killarney Heights block: the rock and substructure, any BAL rating backing the park, and the building envelope. Those set the home.
We build these fixed-price, licence HBL 487805C. Bring us your block and outlook and we will design to it.
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 Killarney Heights 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 Killarney Heights 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 Hawkesbury Sandstone soil, BASIX 2025, Northern Beaches 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.
