A knockdown rebuild in Penshurst is a solid station-suburb play — Federation cottages, inter-war heritage and 1960s-90s brick on 400 to 600m² R2 blocks between Hurstville and Mortdale, with renewal strong on the wider streets.
On the R2 streets, a rebuild resets a dated home. Around the station, the R3 precinct can make medium-density the bigger play on qualifying blocks, and the 600m² duplex minimum applies on the larger lots.
The shale-sandstone interface means the slab is designed off a real geotech, and the pre-war stock carries asbestos and lead paint, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility before you commit.
Buildana manages the complete knockdown rebuild process in Penshurst — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

Renewal on the wider streets
Penshurst's renewal is already strong on the wider streets, where the aging Federation-to-brick stock on 400 to 600m² blocks suits a modern rebuild with the station close.
Around the station, the R3 precinct can make medium-density the bigger play — I check first.
Interface ground and old stock
The shale-sandstone interface means the slab is designed off a real geotech. The pre-war stock carries asbestos and lead paint, so a licensed strip-out leads the demolition.
Both are in the feasibility and the fixed price.
