A duplex in Kyeemagh costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Bayside Council approvals, construction and subdivision under one fixed-price contract.
Kyeemagh Duplex Construction
A duplex in Kyeemagh works on the lots that clear the Bayside 600m2 minimum, with sandy ground and severe flight-path acoustics to plan for. This small foreshore suburb between Brighton-Le-Sands and the airport runs post-war brick on 400 to 700m2 blocks, so the larger lots clear 600 while smaller ones fall short. The suburb sits directly under the runway approach, so ANIP flight-path acoustics are severe and planned in on both dwellings.
The ground is Botany Sands with an elevated water table, so footings and any slab are engineered off geotech to suit rather than assumed. There is limited heritage stock, which keeps the approval path predictable. On a qualifying block a side-by-side duplex works cleanly. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Kyeemagh block: whether it clears the 600m2 minimum, the severe flight-path acoustics, and the sandy-ground footings. 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 Kyeemagh — 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.

Feasibility against 600m2
This small foreshore suburb runs post-war brick on 400 to 700m2 blocks, so the larger lots clear the Bayside 600m2 minimum.
The suburb sits directly under the runway approach, so ANIP flight-path acoustics are severe and planned in on both dwellings.
Sandy ground
The Botany Sands soil with an elevated water table means footings engineered off geotech on both dwellings.
Limited heritage stock keeps the approval path predictable, with older fibro stripped under licence first.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Quick desktop check first — lot size, zoning, frontage — then full site visit if it stacks. Drainage path, neighbour overlooking, slope, services, easements. 600m² (Bayside DCP — R2 dual occupancy) 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 Kyeemagh block's yield — floor plans, elevations, 3D renders, and landscape concept. We optimise for rental return and sale value under Bayside Council's DCP.
⏱The Kyeemagh construction phase. Fixed price, programmed, supervised. Most Kyeemagh duplexes go DA route through Bayside 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.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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
Every Buildana duplex in Kyeemagh is built under a fixed-price contract — feasibility through to dual handover and subdivision.
