A duplex in Camperdown costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Inner West Council approvals, construction and subdivision under one fixed-price contract.
Camperdown Dual Occ. — Feasibility to Handover
A duplex in Camperdown is rarely feasible, because the lots are tight and heritage covers most streets. This inner-west suburb, split between the Inner West Council and the City of Sydney, runs Victorian terraces and Federation cottages on 100 to 350m2 blocks, and on a typical lot the honest answer is a single designed home or a restoration. Heritage Conservation Areas cover most streets, so dual-occupancy is precluded on contributory lots.
The Royal Prince Alfred Hospital and Sydney University precinct drive medical and professional demand, and the ground is Wianamatta Shale engineered off geotech. On the rare larger non-heritage lot a duplex might be possible, but the tight blocks and heritage usually rule it out, so I would rather point you to a single home or restoration than push the wrong scope. Where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your Camperdown block: the heritage status, the tight-lot area, and whether a single home or restoration is the honest scope. That decides the direction.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you honestly what the block allows.
Buildana manages the full duplex development process in Camperdown — from feasibility assessment and architectural design through to DA or CDC approval, and fixed-price construction to dual handover. One builder, one contract, two homes.

How It Works
From First Call to Final Key
Feasibility covers the planning side and the financial side. Yes-or-no on whether the block supports dual occupancy under Inner West Council controls, plus indicative end values, build cost, and likely yield.
⏱Dual occupancy floor plans designed for your Camperdown block — attached or detached configuration, vehicle access, private open space, and full Inner West Council compliance..
⏱Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with Inner West Council or private certifier. We handle RFIs and conditions.
⏱Construction follows a tight programme: dual slabs in one mobilisation, paired frame stand, simultaneous lock-up, then trades rotate between sides for fit-out so no day is lost waiting on availability. The schedule is engineered, not optimistic.
⏱Both dwellings handed over with individual Occupation Certificates. Subdivision lodged for separate titles.
⏱Quality Promise
Buildana delivers Camperdown duplexes as a single project — one contractor accountable from site check to subdivision.
