A home extension in Dean Park grows the 1990s home the family outgrew — sound stock on 550 to 700m² blocks in a quiet school-anchored pocket, where the rear wing adds what the plan lacks.
The clean 1990s fabric keeps the work simple, and the reactive pockets get engineered junctions.
At the $800K to $1.0M median, the friction cost of upsizing builds most of the wing instead.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.
Buildana manages the complete home extension process in Dean Park — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

The outgrown 1990s plan
Dean Park's 1990s homes hold bigger households than planned — and the rear wing solves it: bedrooms, second living and a renewed rear with the schools staying home.
The clean fabric sends the budget into the new space.
Junctions engineered
The reactive pockets get footing junctions engineered to move with the house.
That junction engineering is in the fixed price up front.
