A home extension in Kings Park works solid, honest stock — 1970s to 1990s brick on 550 to 700m² blocks, the sort of practical family homes that were built with room to grow out the back. At a value entry point, a rear wing here adds real liveability for money that would otherwise disappear into the cost of moving.
The brick extends cleanly at ground level. The older homes get a fibro check with a licensed strip-out where found, and reactive pockets get an engineered footing junction between the old house and the new wing so the two move together.
At an $800K to $1.0M median, the friction of upsizing would fund a good part of the addition on its own, and the block depth means the full family plan fits without compromise.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.

Solid blocks, honest value
The 550 to 700m² blocks take a full family addition — second living, bedrooms, alfresco — at an entry point that keeps the maths generous.
The 1970s to 1990s brick extends cleanly, which keeps the structure straightforward and the cost predictable.
Fibro and clay handled
The older places get a fibro check, with licensed removal anywhere it shows.
On reactive pockets the footing junction is engineered to move with the house, and all of it is inside the fixed price from the outset.
