Williamstown’s bayside charm, heritage streetscapes, and growing investment potential make it a prime location for dual occupancy development. But with character overlays, tight streets, and strict council requirements, achieving a successful outcome isn’t just about subdivision—it’s about strategic design.
At Barnes & Matina, we help property owners, downsizers, and mum-and-dad investors unlock value through council-compliant, buildable dual occupancy designs tailored to the nuances of Williamstown. Whether you’re planning side-by-side townhomes, a rear dwelling, or a corner site development, understanding the local planning context is the first step to getting it right.

Is Your Williamstown Property Suitable?
Before jumping into design, we assess:
-
Lot width & depth: Minimum site size, access, and setbacks
-
Zoning: General Residential Zone (GRZ) and overlays
-
Site features: Easements, vegetation, slope, street access
-
Character considerations: Will it blend into the streetscape?
We often help clients determine whether their block works for:
