A knockdown rebuild in Westmead deserves a careful look, because the suburb is dominated by the Westmead Health Precinct and carries strong R3 and R4 zoning near the station. On a lot of these blocks, a duplex or medium-density build beats a single rebuild, and the health precinct gives any dwelling a genuine rental market.
The 1950s to 1970s stock on standard 450 to 650m² blocks is aging into rebuild territory, over Class M shale that takes a standard engineered slab. The older homes usually carry asbestos, so a licensed strip-out leads the demolition regardless of what you build.
I will be straight: if your block is R3 or R4 and clears the 600m² minimum, I will show you the dual-occupancy or medium-density numbers first, because the health-worker rental demand makes the higher-yield play compelling here. Where a single home is genuinely the goal, I build that too.

The health precinct changes the maths
Westmead's health precinct is one of the largest in the country, and it gives any dwelling here a strong, steady rental market from health workers. Combined with the R3 and R4 zoning near the station, that often makes a duplex or medium-density build the smarter return over a single rebuild.
On a block that clears the 600m² minimum, I show you those higher-yield numbers first, because it would be a disservice not to on land zoned for it.
Old stock, asbestos a given
The 1950s to 1970s stock usually carries asbestos, so a licensed strip-out and clearance certificate lead the demolition whatever you build. The Class M shale takes a standard engineered slab off a geotech.
Where a single custom home is genuinely your goal, I build it — but in Westmead, the yield conversation is the one worth having first.

How It Works
From First Call to Final Key
Free site inspection of your Westmead property. We check lot dimensions, Cumberland City Council's planning controls, existing home condition, and potential asbestos.
⏱KDR is the chance to get the design right — the new build doesn't have to mimic the original layout. We start from your block's strengths (orientation, slope, views) and your family's brief, then design the home the original lot always deserved.
⏱Licensed demolition of existing 1950s–1970s-era dwelling. Asbestos removal by certified contractors (if present).
⏱Your new home goes up on the cleared site. Engineered slab sized for Class M soil, frame, roof, fit-out, kitchen, bathrooms, flooring, painting, driveway, and landscaping.
⏱Handover pack: OC, structural certificates, BASIX, appliance manuals and warranties, paint colour schedule, maintenance plan, and the keys. Six-year structural warranty kicks in from OC date — keep the documentation safe for any future sale.
