A custom home in Cromer is a Northern Beaches build without the beachfront price. This quiet inland suburb runs 1960s to 1980s brick on 550 to 800m² blocks, much of it ready for replacement, and a designed home here is strong value at a $2.0M to $2.8M median, minutes from the beaches and Narrabeen Lagoon. The block sizes give real design scope.
Two local factors shape the build. Perimeter lots backing the Narrabeen Lagoon catchment carry BAL-12.5 to BAL-29 bushfire ratings that flow into material selection, and Hawkesbury Sandstone means rock excavation is common, so we test before pricing groundwork. A slab engineered off geotech keeps the substructure predictable on the rock base, and the generous blocks suit a proper family home.
What I would check first on your Cromer block: the BAL rating if you back the catchment, where the sandstone starts under the footprint, and the building envelope. Those set the design.
We build these fixed-price, licence HBL 487805C. Get a BAL-literate quote priced on a test dig.

How It Works
From First Call to Final Key
We start at the kerb. Before a single sketch, we stand on your Cromer 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 Cromer 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.
