Duplex, Semi-Detached & Granny Flats

Two dwellings from one block — the biggest value lever when your land allows it.

Duplex feasibility

Dual occupancy: more dwellings, more value

Where zoning and land size allow, splitting a block into two dwellings — a duplex, a semi-detached pair, or a house plus granny flat — is often the single largest way to unlock the value already in your land. It can mean two homes to keep and rent, one to keep and one to sell, or a full dual-occupancy development.

  • Duplex & semi-detached (dual occupancy)
  • Secondary dwellings / granny flats (from 60m², min 450m² land)
  • Feasibility, zoning and FSR assessed before design
  • Licensed builder oversight from feasibility to handover

We tell you if it stacks up — before you spend

Dual occupancy only creates value when the numbers work. We identify duplex or semi potential, resolve zoning constraints, and clarify the capital pathway first — so you commit to a build that adds value, not one that overreaches your block.
