A duplex in Clyde costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Cumberland City Council approvals, construction and subdivision under one fixed-price contract.
Duplex Builder in Clyde
A duplex in Clyde is a feasible dual-occupancy on the residential-pocket lots that clear the Cumberland minimum, in a suburb undergoing significant transformation. The former Clyde refinery site is being redeveloped, and the established residential pockets carry post-war housing with renewal potential, so a Torrens-title duplex on a qualifying lot is a sound play at a $900K to $1.1M median close to the station. Much of the suburb is industrial and transforming, so the residential streets are the focus and the area is the first check.
The ground is engineered off geotech to suit the specific lot, and on a qualifying block a side-by-side duplex works cleanly. Where the existing home carries fibro a licensed asbestos strip-out comes first, which matters near a former industrial site. I would confirm any contamination status on parcels adjoining the redevelopment.
What I would check first on your Clyde block: whether it sits in a residential pocket and clears the Cumberland minimum, any contamination near the former refinery, and the footing design. Those set the dual-occ.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what dual-occupancy it carries.
Buildana manages the full duplex development process in Clyde — 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.

Residential pockets, transforming suburb
The former Clyde refinery site is being redeveloped, and the established residential pockets carry post-war housing with renewal potential.
A Torrens-title duplex on a lot clearing the Cumberland minimum is a sound play at a $900K to $1.1M median near the station.
Contamination check
The ground is engineered off geotech to suit, and on a qualifying block a side-by-side works cleanly.
Near the former refinery a contamination check comes first, with older fibro stripped under licence.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Clyde block — lot size (typical 450–650m²), width, R2 Low Density & R3 Medium Density zoning, setbacks, FSR, landscaped area requirements under Cumberland City Council's LEP and DCP. Minimum lot for duplex: 600m². You'll know viability before spending on design. Design phase covers unit layout, access, parking, private open space, and waste management for dual occupancy on your Clyde site. You approve final plans before we move to lodgement.
⏱The Clyde construction phase. Fixed price, programmed, supervised. Duplex approvals get scrutinised harder than single dwellings — neighbour notification, overshadowing, privacy, traffic, waste. Our SEE addresses each on the front foot rather than reactively. Cleaner submission, fewer conditions, faster CC. Fixed-price construction of both dwellings from slab to keys. Class M engineered footings, frame, lock-up, internal fit-out, and external works. Weekly progress reports.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Subdivision registration starts in parallel with final fitout so titles issue close to handover, not 6 months after. Buildana coordinates the surveyor and Cumberland City Council clearance — important if you're planning to sell one side immediately to fund the next move.
⏱Quality Promise
We build duplexes in Clyde end-to-end — feasibility, design, DA/CDC, dual-slab construction, subdivision. One contract.
