A duplex in Haberfield 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.
Building Duplexes in Haberfield
Let me be straight about a duplex in Haberfield: it is precluded across virtually the whole suburb. Haberfield is Sydney's Federation Garden Suburb, and almost the entire area is a single Heritage Conservation Area protecting the Queen Anne villas and bungalows on their garden blocks. Demolition and dual-occupancy are not on the table here, so an honest answer saves you a wasted feasibility.
What this suburb rewards instead is Federation villa restoration and sympathetic rear additions that keep the protected streetscape intact. On 350 to 700m² garden blocks at a $2.5M to $4.5M premium market, the value is in the heritage character, not in splitting the block. We work within those controls and tell you plainly what is possible.
What I would check first on your Haberfield property: the heritage listing, and what sympathetic works the controls actually permit. A duplex almost never features.
We build these fixed-price, licence HBL 487805C. Let us check your block's controls before you plan.
Buildana manages the full duplex development process in Haberfield — 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
Quick desktop check first — lot size, zoning, frontage — then full site visit if it stacks. Drainage path, neighbour overlooking, slope, services, easements. Varies by precinct (terraces dominant — duplex feasibility limited) minimum is just the entry ticket; the real feasibility is whether two compliant dwellings actually fit and sell.
⏱Our architect designs both dwellings to maximise your Haberfield block's yield — floor plans, elevations, 3D renders, and landscape concept. We optimise for rental return and sale value under Inner West Council's DCP.
⏱Most Haberfield duplexes go DA route through Inner West Council — CDC pathways for dual occupancy are restrictive on most R2 blocks. We pre-meet with council planners on borderline sites to confirm support before lodgement, which avoids a 3-month round trip on RFIs.
⏱Both dwellings built simultaneously — engineered slabs (Class M soil), frame, lock-up, fit-out. Milestone updates from your project manager.
⏱Final inspections, dual OCs issued, subdivision registered with LRS. Each dwelling gets its own title, services, and 6-year structural warranty. Ready to rent, sell, or occupy.
⏱Quality Promise
Buildana delivers Haberfield duplexes as a single project — one contractor accountable from site check to subdivision.
