A duplex in Beverly Hills costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Georges River Council approvals, construction and subdivision under one fixed-price contract.
Dual Occupancy Developments in Beverly Hills
A duplex in Beverly Hills works where the block clears Georges River's 600m² minimum, and near King Georges Road there is more on the table. The Federation cottages, inter-war homes and 1960s to 1990s brick sit on 400 to 600m² R2 blocks, so some make the dual-occupancy cut and some do not, while the R3 medium-density corridor along King Georges Road opens a townhouse yield on the right block. Renewal here is strong either way.
The Georges River area's ground generally behaves, so the duplex slab and footings off geotech stay predictable, and where older homes carry fibro a licensed asbestos strip-out comes first. A compliant duplex on a clearing R2 block moves through Council on a known path, and the rail location supports both dwellings for resale or rent.
What I would check first on your Beverly Hills block: whether it clears the 600m² minimum or sits in the R3 corridor, and any asbestos before demolition. Those decide the play.

How It Works
From First Call to Final Key
Site visit, title search, and planning assessment for your Beverly Hills block. We check lot dimensions against Georges River Council's minimum (600m² under Georges River LEP 2021), review overlays, drainage, access, and services.
⏱Design has to satisfy four audiences at once: Georges River Council, the future buyer or tenant, the certifier, and you. Each pull in a different direction — our job is to land plans that work for all four.
⏱We lodge and chase your approval — DA through Georges River Council for most duplexes, or CDC where eligible. R2 Low Density zoning in Beverly Hills.
⏱Building both sides in parallel halves the loan interest holding cost vs sequential builds. Bulk material orders for cabinetry, tiles, fixtures cut unit cost.
⏱Strata or Torrens title subdivision completed. Separate OCs, individual metering, 6-year structural warranty per dwelling.
