Quick Answer

A knockdown rebuild in Kogarah costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Georges River Council approvals, and construction under one fixed-price contract.

Kogarah KDR — Single Contract, New Home

A knockdown rebuild in Kogarah is worth weighing carefully, because this is the medical and education precinct of the LGA — St George Hospital, St George Private and the Kogarah CBD around the station, with R3 and R4 redevelopment dominant. On a lot of blocks, the higher-yield play beats a single rebuild.

The healthcare-staff and student tenant demand here is genuine, so on R3 or R4 land over the 600m² minimum, I show you the duplex or medium-density numbers first. On the R2 side streets with Federation and inter-war character, a single rebuild — or a restoration on the character homes — is the play.

The ground is the shale-sandstone interface with reactive clay pockets, so 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.

We rebuild fixed-price, licence HBL 487805C. Get our feasibility — rebuild or higher-yield — before you commit.

Buildana manages the complete knockdown rebuild process in Kogarah — 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.

The hospital precinct changes the maths

Kogarah's medical and education precinct — St George Hospital, St George Private, the CBD — generates genuine healthcare-staff and student tenant demand. Combined with the dominant R3 and R4 zoning, that often makes a duplex or medium-density build the smarter return over a single rebuild.

On a block over the 600m² minimum on zoned land, I show you those numbers first.

Side-street character and interface ground

On the R2 side streets, the Federation and inter-war character stock suits a single rebuild — or a restoration where the home is well-kept. The shale-sandstone interface with reactive clay pockets 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.

How It Works

From First Call to Final Key

Everything that has to be right before we touch the ground. KDR feasibility is two questions: what can the block legally support, and is it cheaper to build new than fix old. We answer both in writing within a week, with cost ranges grounded in current Kogarah market data — not generic Sydney averages. New home designed for your Kogarah block — maximising FSR, orientation, and streetscape. Working drawings, engineering, and BASIX prepared. CDC or DA lodged with Georges River Council.

The Kogarah construction phase. Fixed price, programmed, supervised. Full demolition management: asbestos survey report, licensed removal where required, structural demolition, site clearing, temporary fencing, and dust/noise management. Georges River Council demolition permit obtained beforehand. Build sequence: site prep, slab pour, frame stand, roof, brickwork, lock-up, plumbing and electrical rough-in, plaster, internal fit-out, kitchen install, tiling, flooring, painting, external works, final clean. Each stage signed off before payment release.

The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Defect-free handover inspection, OC issued, keys in hand. Permanent services reconnected, landscaping complete, 6-year structural warranty, and full maintenance guide provided.
