New Build

New homes and duplexes, planned land-first

Completed modern new home

A new build is the clearest opportunity to align a home with what the land can actually support. Before design begins, we assess site capability, zoning, and development potential — so the home you build matches both your family’s needs and the market fundamentals of the street.

GY & CO delivers new homes, knock-down rebuilds, duplex developments and granny flats across the North Shore and Eastern Suburbs, with licensed builder oversight from feasibility through to handover.

  • Feasibility and zoning review before design commitment
  • Duplex and dual-occupancy potential assessment
  • Granny flat and secondary dwelling options
  • Fixed-price contracts and controlled execution
