A knockdown rebuild in Penrith costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Penrith City Council approvals, and construction under one fixed-price contract.
Demolish and Rebuild in Penrith
A knockdown rebuild in Penrith is one of the genuine value plays in Sydney — the LGA's CBD with Westfield, Nepean Hospital and the station, aging 1960s-80s stock on 450 to 750m² blocks, and the lowest duplex minimum in Sydney at 450m². The rebuild and dual-occupancy maths here genuinely works.
On the R2 streets, a rebuild resets a dated home affordably. Against the 450m² duplex minimum, most blocks qualify, so I run the duplex numbers as standard. Near the CBD, R4 high-rise value can dominate, and on the western edge the Hawkesbury–Nepean flood planning controls apply.
The Wianamatta Shale takes a slab designed off a real geotech, and the older stock carries asbestos, so a licensed strip-out leads the demolition.

The maths genuinely works
Penrith's affordable land, aging stock and 450m² duplex minimum — the lowest in Sydney — make the rebuild and dual-occupancy maths genuinely work. Add the hospital, Westfield and the station, and a quality build here has real demand behind it.
I run the duplex numbers as standard, because most blocks qualify.
Flood west, precinct core
On the western edge, the Hawkesbury–Nepean alluvial corridor brings flood planning controls that can set floor levels — checked upfront. Near the CBD, R4 high-rise value can dominate on qualifying blocks.
The Wianamatta Shale takes a slab designed off a real geotech, and the older stock's asbestos is handled with a licensed strip-out.

How It Works
From First Call to Final Key
Free site inspection of your Penrith property. We check lot dimensions, Penrith 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 1960s–1980s fibro/brick veneer (Cranebrook/Werrington/Cambridge Park/Kingswood/St Marys) + 1990s–2010s brick (Glenmore Park/Cambridge Gardens) + 2010s+ master-planned (Jordan Springs/Caddens/Claremont Meadows)-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.
⏱Quality Promise
Buildana handles Penrith KDR end-to-end — old house out, new house in, one contract, one contractor, one defined timeline.
