About RHOSH Group
A True Peninsula Team
RHOSH Group is a Mornington Peninsula building team founded by Rhys Palmer and Josh Westerman, each bringing over 15 years of experience delivering quality homes across the Peninsula.
We specialise in custom home builds, renovations and extensions, working closely with homeowners to deliver thoughtful, well-built spaces that suit the way they live.
As local builders, we understand the unique considerations of building on the Peninsula – from coastal conditions and sandy soils to heritage overlays and BAL requirements.
We take a calm, organised approach to every project, prioritising clear communication, realistic planning and well-managed sites from start to finish.
Rhys and Josh – together, we’re RHOSH.
