A duplex in Eastwood costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, City of Ryde Council approvals, construction and subdivision under one fixed-price contract.

Ryde's duplex minimum is 580m², not the 600m² most of Sydney assumes, and in Eastwood, where blocks run 550 to 900m², that 20m² discount pulls extra sites over the line every year. One wrinkle first: the suburb is split between the City of Ryde and City of Parramatta, and Parramatta's side holds the standard 600m². Which council owns your street is the first fact worth establishing, because it can be the whole answer.
Past that gate, Eastwood is a strong duplex suburb. Medians at $2.1M to $3.0M, a station in the suburb, and one of Sydney's busiest Asian-Australian commercial centres feeding demand for new family homes on both sides of a pair. Heritage pockets around Brush Farm Park need checking. Most streets do not carry them.
What I would check first on an Eastwood block: which council it sits in and the minimum that follows, the heritage status near Brush Farm Park, and the frontage. Those decide feasibility.
We build these fixed-price, licence HBL 487805C. Tell us your address and we will confirm the LGA, the minimum and the feasibility in one go.

Which council owns your street?
Eastwood is split between the City of Ryde and City of Parramatta, and the minimums differ: Ryde's duplex minimum is 580m², Parramatta's is the standard 600m². On a suburb running 550 to 900m², that 20m² gap pulls extra Ryde-side sites over the line every year.
So the first fact worth establishing is which council owns your street, because it can be the whole answer.
A strong duplex suburb past that gate
Past the LGA question, Eastwood is strong: a $2.1M to $3.0M median, a station in the suburb, and one of Sydney's busiest Asian-Australian commercial centres feeding demand for new family homes on both sides of a pair.
Heritage pockets around Brush Farm Park need checking, but most streets do not carry them. Tell us the address and we will confirm the LGA, the minimum and the feasibility in one go.

How It Works
From First Call to Final Key
Free feasibility check on your Eastwood block. We measure frontage width, confirm zoning (R2 Low), check minimum lot size against 580m² requirement, and review City of Ryde Council's DCP controls. Written feasibility report within 5 business days.
⏱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. We work the design until both sides feel like proper homes, not mirror-image apartments.
⏱DA through City of Ryde Council (40–90 days) or CDC (10–15 business days). Eastwood is zoned R2 Low. Construction Certificate obtained before works commence.
⏱Dual construction runs 9–14 months. Engineered slabs sized for Class M soil, simultaneous frame-up, staggered fit-out for efficiency. Your project manager coordinates all trades and inspections.
⏱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. Whatever the next owner or buyer asks for is in the file.
⏱Quality Promise
Our Eastwood duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
