Custom & Passivhaus Home Builders on Tasmania's East Coast

Designing and building luxury coastal homes along Tasmania's east coast — Freycinet, Coles Bay, Bicheno and beyond, where architecture meets the sea.

Zanetto Builders builds luxury coastal Forever Homes along Tasmania’s East Coast — St Helens, Coles Bay, Falmouth, Bicheno and Freycinet. Four completed, photographed east-coast projects prove it isn’t a service-area pin. Every home is detailed for the marine environment and delivered open-book, by an award-winning team.

Building your Forever Home on the East Coast

Tasmania’s east coast is a string of extraordinary places — Freycinet’s pink-granite peaks, Wineglass Bay, the quiet beaches of Swansea and Bicheno. It’s where some of the state’s most ambitious coastal homes are built, framing the sea and the landscape with restraint and luxury.

We build custom and Passivhaus homes the length of the east coast, delivering architectural retreats and Forever Homes engineered for the coastal climate. Remote and exposed sites are our speciality — we bring the planning, logistics and craftsmanship that these locations demand.

Four east-coast projects, completed and photographed

The proof is on the coast already. At Coles Bay — the doorstep of Freycinet — Patsy and the Picnic Island Luxury Escape. At Falmouth, Newave. In St Helens itself, Fysh Place. Different briefs, one constant: coastal homes detailed to handle the environment they’re built to celebrate.

What building out here actually involves

  • Exposed and remote sites — logistics, sequencing and trade coordination are half the project; our process was built for exactly this
  • Marine-grade detailing — salt, wind and sun shape every material and fixing decision
  • Bushfire (BAL) ratings — common on coastal-bush blocks from Swansea to Binalong Bay, and priced into your 48-hour feasibility up front
  • Performance in absence — many east-coast homes are retreats; a high-performance envelope keeps them dry, healthy and inexpensive to hold between visits
