A duplex in Maroubra 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.
Duplex Builder in Maroubra
A duplex in Maroubra is a strong coastal dual-occupancy play, but the blocks and the heritage shape it. The Federation and post-war stock runs 350 to 700m², so the larger parcels clear Randwick's dual-occupancy minimum, while Heritage Conservation Areas cover the village core and pockets that restrict demolition. The R3 zoning along Maroubra Road and Anzac Parade can open a townhouse yield on the right block.
The sandstone-dominant ground behaves for slab and footings off geotech, with substantial fall toward Maroubra Beach on the eastern edge, and coastal-facing builds carry salt-grade specifications. Where an older home carries fibro, a licensed asbestos strip-out leads the demolition.
What I check first on your Maroubra block: whether it clears the dual-occupancy minimum, whether you sit inside a Heritage Conservation Area, and whether coastal exposure drives salt-grade specs. Those decide the play.

Heritage, coast and zoning in Maroubra
Maroubra varies block to block for duplex. The village core and several pockets sit inside Heritage Conservation Areas where demolition of a contributing cottage is restricted, so those blocks may suit a sympathetic dual occupancy rather than a clean rebuild. Along Maroubra Road and Anzac Parade, R3 zoning can make a townhouse yield the better play. The larger non-heritage R2 blocks on the quieter streets are where a straightforward Torrens duplex sits.
With blocks from 350 to 700m², whether you clear the minimum genuinely depends on your survey. I check that against the heritage and zoning layers before anyone draws a plan.
Coastal specs near the beach
Maroubra falls to the beach on its eastern edge, and coastal-facing blocks carry salt-grade specifications: marine-grade fixings, corrosion-resistant hardware and durable claddings that survive the salt air. Priced properly, a coastal Maroubra duplex lasts. Underneath, the sandstone ground is stable for two slabs off geotech. Get the survey, heritage and exposure checked, and the build runs predictably.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Maroubra block — lot size (typical 350–700m²), width, R2 Low zoning, setbacks, FSR, landscaped area requirements under Randwick 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 Maroubra site. You approve final plans before we move to lodgement.
⏱The Maroubra 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 Randwick City Council clearance — important if you're planning to sell one side immediately to fund the next move.
