Custom & Passive House Home Builders in Coles Bay & Freycinet

Coastal Forever Homes at Coles Bay and across the Freycinet peninsula, built for the granite, the weather and one of Tasmania's most extraordinary landscapes.

Zanetto Builders builds custom and Passive House 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 Passive House 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.

Building at Coles Bay and Freycinet: what the site demands

Coles Bay is one of the most beautiful places in Australia to build and one of the least forgiving. The granite, the water and the light are the reason people come — and each of them sets a condition.

Exposure is total. There is very little shelter on this peninsula. Wind classification drives structure, glazing and roof detailing, and the same openings that frame Freycinet have to perform thermally rather than simply exist.

Bushfire ratings are the norm, not the exception. Coastal-bush blocks through Coles Bay and the Freycinet approaches routinely carry a Bushfire Attack Level under AS 3959, assessed on vegetation, slope and separation. It materially changes construction — see building in a bushfire zone in Tasmania — and we price it into your 48-hour feasibility rather than treating it as a surprise.

Distance costs money in freight and in time. Coles Bay is a long way from a supplier. Trades travel, deliveries consolidate, and the program has to be built around that reality. We cost it openly; it is not a contingency we bury.

Retreats that sit empty, and why that matters

Many Coles Bay homes are holiday houses, and an unoccupied coastal home is exactly where conventional construction fails. Nobody is opening windows, nobody is running heating, and nobody notices a damp corner for a month.

An airtight, well-insulated envelope with heat-recovery ventilation keeps the interior dry and stable on almost no energy, so the house is ready to be comfortable within an hour of arrival rather than a day — and it is not quietly growing mould between visits. That is the same building science behind our certified work, applied where it earns its keep hardest.
