Dual Occupancy Developments in Canterbury
A duplex in Canterbury is a feasible dual-occupancy on the lots that clear the Canterbury-Bankstown 600m2 minimum, with R3 adding options and its own station. This suburb runs 1920s to 1960s stock on standard blocks with heritage character in some areas, and at a $1.3M to $1.6M median a Torrens-title duplex on a qualifying lot is a strong play near the station and racecourse. Some lots fall short and heritage sits in pockets, so both are checked first.
The ground is engineered off geotech to suit the specific lot, and R3 zoning means a well-placed block may suit medium density instead. On a qualifying R2 lot a side-by-side duplex works cleanly. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Canterbury block: whether it clears the 600m2 minimum, the heritage status, and any R3 potential. Those set the dual-occ.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you the best use of it.

Feasibility against 600m2
This suburb runs 1920s to 1960s stock on standard blocks with heritage character in some areas, so the larger lots clear the 600m2 minimum.
At a $1.3M to $1.6M median a Torrens-title duplex on a qualifying lot is a strong play near the station and racecourse.
R3 option
The ground is engineered off geotech to suit, and R3 zoning means a well-placed block may suit medium density.
On a qualifying R2 lot a side-by-side duplex works cleanly, with older fibro stripped under licence first.

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 Canterbury block against Canterbury-Bankstown 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 & R3 Medium 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 Canterbury duplexes as a single project — one contractor accountable from site check to subdivision.
