A home extension in Prospect has room to be generous, because the blocks are — 550 to 700m² under 1970s to 1990s stock on the reservoir side, with the kind of depth that lets a rear addition go on without swallowing the yard. It is the sort of land most families want and rarely get, so building beats moving to find it.
The brick from this era extends cleanly. The older homes get a fibro check with a licensed strip-out where it is found, and where the ground turns reactive the footings are detailed so old and new move as one.
At an $850K to $1.1M median, the cost of upsizing would build a good part of the wing on its own, and the motorway access keeps everyday life straightforward through the build.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.

Room to actually extend
Prospect's generous blocks fit a rear addition without compromise — second living, bedrooms and alfresco with the yard still intact — and the motorway access keeps everything practical.
The 1970s to 1990s brick takes the wing cleanly at ground level.
Fibro and reactive clay covered
The older homes get a fibro check with a licensed strip-out wherever it turns up.
On the reactive pockets the footing junction is engineered to move with the house, and all of it is inside the fixed price from the outset.
