Hobsons Bay extensions
Same council, different rulebook per suburb.
An extension in Williamstown answers a very different question to one in Altona. Williamstown reads first through the heritage overlay and streetscape. Altona and Seaholme read through coastal exposure, post-war brick veneer construction and slab-on-ground floor plans that behave nothing like a Victorian subfloor. Newport and Spotswood sit somewhere between the two.
RenoWorx runs house extensions across all of it with the same municipal team and the same building surveyors. That means a planning approach that matches your specific suburb, not a generic Hobsons Bay template — and a build program that survives contact with actual council review.

"From the first meeting through to handover, RenoWorx made what we expected to be a stressful renovation feel completely manageable. The finish is exceptional — every detail considered, every trade-person professional. We could not recommend them more highly."
Sarah & James
Williamstown · Whole-home renovation
"The level of detail and the quality of the trades was clearly a step above. Our extension feels like it was always part of the original house."
"We interviewed four builders. RenoWorx were the only ones who actually listened. The kitchen is everything we hoped for."
