A duplex in Daceyville costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Randwick City Council approvals, construction and subdivision under one fixed-price contract.
Dual Occupancy Developments in Daceyville
A duplex in Daceyville is precluded, because the entire suburb is a Heritage Conservation Area. Sydney's first government-planned garden suburb from 1912 runs Federation cottages and bungalows on 400 to 700m2 blocks, and stringent Council controls on form, colour and materials cover every lot, so the honest scope is restoration or a single sympathetic home, not a dual-occupancy. I would rather tell you that up front than take you down a path Council will refuse.
The garden-suburb character is exactly what is protected, so splitting a contributory block is not on the table, and any approved works have to answer the heritage controls. The ground is sandstone, engineered off geotech. For dual-occupancy yield, neighbouring non-heritage suburbs make far more sense, and I will point you to them.
What I would check first in Daceyville: the heritage controls on your lot, the realistic restoration scope, and the better dual-occ options nearby. That is the honest starting point.
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 Daceyville — 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
Free feasibility check on your Daceyville block. We measure frontage width, confirm zoning (R2 Low), check minimum lot size against 600m² requirement, and review Randwick City Council's DCP controls.
⏱Two dwellings, one site — design is mostly about geometry. Frontage split, party wall position, garage stacking, private courtyard size, and the streetscape elevation a certifier will actually approve.
⏱DA through Randwick City Council (40–90 days) or CDC (10–15 business days). Daceyville is zoned R2 Low.
⏱Dual construction runs 9–14 months. Engineered slabs sized for Class M soil, simultaneous frame-up, staggered fit-out for efficiency.
⏱Two homes, two titles, two OCs, two warranty packs. We hand over a clean documentation set per dwelling: certifier reports, BASIX certs, structural sign-offs, appliance warranties, maintenance schedules.
