Quick Answer
A knockdown rebuild in Wiley Park costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Canterbury-Bankstown Council approvals, and construction under one fixed-price contract.
New Home on Your Wiley Park Block
A knockdown rebuild in Wiley Park suits the aging 1930s to 1960s stock, with active residential renewal and its own train station. The homes sit on standard blocks with R2 and R3 zoning, so a rebuild gives you a modern custom home, and the larger R3 blocks can suit a duplex where the numbers favour it. The era of the stock means the demolition is the main thing to plan.
The ground carries reactive clay, so the new slab is engineered off geotech. The 1930s to 1960s stock commonly carries asbestos in additions and wet areas, so a licensed strip-out and clearance certificate lead the demolition.
What I check first on your Wiley Park knockdown rebuild: whether a single home or a duplex suits the block and zoning, any asbestos in the demolition, and the reactive clay for the new slab. Those decide the play.

Rebuild or duplex amid active renewal
Wiley Park's aging 1930s to 1960s stock on standard blocks suits a knockdown rebuild, and its own station plus active residential renewal keep the momentum strong. On a standard R2 block, a single modern custom home is the play. On the larger R3 blocks, a duplex can be the better play where the numbers favour it, so I run both first.
It resets a tired home entirely rather than renovating around aged bones, which suits the renewal demand here.
Reactive clay and asbestos
The reactive clay under Wiley Park means the new slab is engineered off a real geotech to stay stable against clay movement. The 1930s to 1960s stock commonly carries asbestos in additions and wet areas, so a licensed strip-out and clearance certificate lead the demolition before the rebuild. I map both as part of the feasibility.

How It Works
From First Call to Final Key
KDR starts with an honest look at the existing house. Sometimes it's worth keeping. Most Wiley Park homes from the 1930s–1960s — especially fibro and brick-veneer — are beyond the point where renovation makes sense. We tell you straight.
⏱Demolition is pre-approved to run parallel with rebuild design. Asbestos cleared, services abolished, site stripped in a single mobilisation. Geotech reconfirms Class M soil with the old house gone.
⏱New house goes up on the same footprint or a better one, whichever serves the block. Modern NCC envelope, better orientation, fit-for-purpose room sizes. The suburb stays the same; the house finally fits it.
⏱Final handover: new OC, six-year structural warranty, all the documentation on your Wiley Park block you'd get on a greenfield build. The only difference is you still live in the street you chose.
⏱Quality Promise
Buildana handles Wiley Park KDR end-to-end — old house out, new house in, one contract, one contractor, one defined timeline.
