Custom & Passivhaus Home Builders in Devonport

Building premium custom homes across Devonport and the north-west coast — coastal homes designed for the Mersey River, the bluff, and the big northern light.

Zanetto Builders builds custom Forever Homes in Devonport and across Tasmania’s north-west coast — architecturally designed, performance-built and delivered through open-book pricing and a 48-hour feasibility, by an award-winning Tasmanian team.

Building your Forever Home in Devonport

Devonport sits where the Mersey River meets Bass Strait — the arrival point for the Spirit of Tasmania and the gateway to the north-west coast. Coastal building here demands homes that stand up to salt air and exposure while making the most of the northern light and water views.

We build across Devonport, Spreyton, Latrobe and the Don Valley, delivering Passivhaus-grade homes engineered for coastal durability and year-round comfort. From the bluff to the riverfront, our craftsmanship is built to last in this exposed northern environment.

Pricing and running a Devonport build

Devonport builds are run from our Launceston headquarters at St Leonards, about an hour and a quarter down the Bass Highway — close enough for proper supervision, with travel and delivery logistics priced into the job from the start. Before design goes anywhere, our 48-hour feasibility gives you a build cost within 10%, priced across more than 90 cost categories, so you can weigh up a block at Devonport, Latrobe or Spreyton on real numbers. Our cost to build in Tasmania guide sets out where genuine custom pricing sits in 2026.

Coastal exposure on the bluff and around the Mersey mouth also makes building performance worth taking seriously — a sealed, insulated, properly ventilated home stays warm and dry where an ordinary one grows cold and damp. If that sounds like a house you’ve lived in, read why Tasmanian homes are cold and damp.

Building in Devonport — your questions answered

Do you build in Devonport and the north-west coast?+

Yes — Zanetto Builders builds custom Forever Homes across Tasmania’s north-west coast, delivered open-book with a 48-hour feasibility.

How much does it cost to build a custom home in Devonport?+

A genuine custom home with us typically starts around $5,000 per square metre in 2026, priced from each home’s own design; most of our Forever Homes fall between $850,000 and $4 million. We prepare a feasibility within 10% of the real build cost in 48 hours.

Do you build certified Passivhaus homes in the north-west?+

Yes. Zanetto Builders has the largest and most experienced certified Passive House team in Tasmania, and delivered a certified Passivhaus at Blackmans Bay (Bluebush) achieving a heating demand of 10 kWh/m²a and 0.5 air changes per hour — independently certified, not just built to principles.

How do you manage Devonport builds from Launceston?+

Devonport is about an hour and a quarter from our Launceston headquarters at St Leonards — an easy run down the Bass Highway. We service all of Tasmania from three offices (Launceston, Hobart and St Helens), and site supervision, trades and deliveries are built into the program, so a Devonport build runs the same as one down the road from us.

How long does a custom build in Devonport take?+

Every home is priced and programmed from its own design, so we won’t quote a one-size-fits-all timeframe — but the program is set before you sign, and our 48-hour feasibility gives you cost certainty within 10% at the very start. From there, design, approvals and construction each run to a schedule you can see, open-book, the whole way.
