A duplex in Tempe is limited, because the lots are small and the suburb is boxed in by the M8 corridor and the Cooks River. Victorian terraces, Federation cottages and post-war homes sit on 200 to 500m2 blocks, so duplex feasibility is constrained and heritage pockets narrow it further. On a $1.6M to $2.4M market, renovation or a single rebuild is often the realistic move.
The ground is Wianamatta Shale with alluvial pockets near the Cooks River, so footings and the slab are engineered to suit, and the airport flight-path proximity adds acoustic requirements worth confirming. Heritage pockets and the WestConnex edge are checked before design.
What I would check first on your Tempe block: the lot size, the heritage status, and the flight-path acoustic overlay, because those shape what is possible.
We build and renovate fixed-price, licence HBL 487805C. Send me the block and I will tell you honestly what it can carry.
Buildana manages the full duplex development process in Tempe — 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.

Small lots, boxed-in suburb
Tempe runs terraces, cottages and post-war homes on 200 to 500m2 blocks, boxed in by the M8 and Cooks River.
Lot sizes and heritage pockets constrain duplex feasibility, so renovation or a single rebuild often leads.
River alluvium and flight path
Wianamatta Shale with alluvial pockets near the Cooks River means footings and slab engineered to suit.
Airport flight-path proximity adds acoustic requirements, confirmed before design.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Tempe block — lot size (typical 200–500m²), width, R1/R2 General/Low zoning, setbacks, FSR, landscaped area requirements under Inner West Council's LEP and DCP. Minimum lot for duplex: Varies by precinct (terraces dominant — duplex feasibility limited). 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 Tempe site. You approve final plans before we move to lodgement.
⏱The Tempe 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 Inner West Council clearance — important if you're planning to sell one side immediately to fund the next move.
