A duplex in Croydon Park costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Burwood Council approvals, construction and subdivision under one fixed-price contract.
Building Duplexes in Croydon Park
Croydon Park hides a number most owners do not know: Burwood Council's duplex minimum is 550m², lower than the 600m² next door in the Inner West and Canterbury-Bankstown. On a suburb running 300 to 600m² blocks, that 50m² difference pulls a meaningful band of lots over the line that would fail one street away. If your block sits in the 550 to 600m² range, you may hold a duplex site your neighbours across the LGA boundary cannot match.
Two checks before anyone celebrates. Heritage Conservation Areas cover several streets, Georges River Road and Tangarra Street among them, and a contributory Federation or Californian Bungalow home takes the option off the table. Clear both hurdles and the $2.0M to $3.2M median makes the maths interesting.
What I would check first on a Croydon Park block: whether it clears the 550m² Burwood minimum, the heritage status, and the frontage. Those decide it.

The 550m² number most owners miss
Burwood Council's duplex minimum is 550m², lower than the 600m² next door in the Inner West and Canterbury-Bankstown. On a suburb running 300 to 600m² blocks, that 50m² difference pulls a meaningful band of lots over the line.
So a block in the 550 to 600m² range may be a duplex site your neighbours across the LGA boundary cannot match. The council boundary is the quiet advantage here.

How It Works
From First Call to Final Key
A duplex is really a feasibility problem wearing a construction outfit. Before anything else, we verify your Croydon Park block against Burwood Council's LEP — lot size, frontage, FSR, landscape area. If it doesn't stack up, you find out in a week, not after 3 months of design.
⏱Design runs dual from day one. Two dwellings, one coherent streetscape, party-wall acoustics and fire rating built into the structure rather than bolted on. The plan accommodates R2 Low Density zoning without looking like two mismatched houses sharing a fence.
⏱Approval and construction get sequenced together. Slab pours are choreographed so the trades show up once, frame up both sides, and keep rolling. Two separate meters, two separate services, but one crew, one programme.
⏱Handover is dual. Both dwellings walked at the same time, both OCs in the same issue, both titles subdivided before settlement. You leave the final inspection with the option to live in one and rent the other, or to sell both.
⏱Quality Promise
Buildana delivers Croydon Park duplexes as a single project — one contractor accountable from site check to subdivision.
