A home extension in Asquith grows the family home on generous land — 1960s-1990s brick on 700 to 1,200m² blocks where the rear wing fits without the yard noticing and the station-precinct R3 gets the zoning check.
The bush-edge lots get the BAL assessment, the sandstone is read before the dig, and the junctions are engineered.
At the $1.8M to $2.6M median, the wing beats the cost of upsizing on the upper North Shore fringe.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with zoning and BAL checked, before you commit.
Buildana manages the complete home extension process in Asquith — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Room the block gives up freely
Asquith's 700 to 1,200m² blocks hold a full family wing without touching the yard — second living, bedrooms, a suite — with the brick taking the additions confidently once engineered.
Near the station, the R3 value gets the check first.
Bush and rock handled
BAL ratings apply on the bush-edge lots, and the sandstone is read before the dig.
Both the BAL materials and the rock read are in the fixed price up front.
