Custom & Passivhaus Home Builders in Coles Bay & Freycinet

Zanetto Builders builds custom and Passivhaus homes at Coles Bay and across the Freycinet peninsula — the gateway to Freycinet National Park. Patsy is a completed Zanetto home at Coles Bay. We detail every home for salt, wind, bushfire (BAL) and national-park siting, delivered open-book.

Building your Forever Home in Coles Bay

Coles Bay sits beneath the pink-granite Hazards, the gateway to Freycinet National Park and Wineglass Bay. It is one of Tasmania’s most spectacular — and most tightly held — coastal addresses, where a home has to earn its place in an extraordinary landscape without fighting it.

We build custom and Passivhaus homes throughout Coles Bay and the Freycinet peninsula, from permanent coastal residences to refined holiday retreats. Each is designed for the light, the water and the marine environment — and built to stay effortlessly comfortable all year, however exposed the site.

We’ve built here — this is real ground

This isn’t a service-area pin on a map. Patsy is a completed Zanetto home at Coles Bay — detail-focused, and delivered with the constant communication its owners singled out. Nearby, the Picnic Island Luxury Escape sits off the Freycinet coast. Further up the coast we’ve built at St Helens and Falmouth — real, photographed east-coast projects, not promises.

What building on the Freycinet coast actually involves

Salt, wind and exposure — materials, fixings and detailing specified for a harsh marine environment, so the home ages gracefully rather than corroding.
Bushfire (BAL) and national-park proximity — considered siting, construction and planning where the bush meets the coast.
Access and logistics — a remote, sought-after location where careful programming and supply keep a build on track.
Designing for the view — orientation and glazing that frame the Hazards and the water while still performing thermally.
