Builders Devonport — Custom Home Builders

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 Passive House-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.

What a Devonport build involves

Devonport sits in a genuinely coastal environment, and the Mersey mouth and bluff areas take the full force of it.

Salt and wind together. Exposure off Bass Strait drives both structural wind classification and material selection. Fixings, flashings and coatings all need to be specified for a marine environment — the failures show up in the connections long before they show up in the finishes.

Northern light is an asset worth designing for. Devonport’s aspect over the water is one of the better orientations in the state if the design uses it: north light for warmth, controlled glazing so the same windows do not bleed heat overnight, and shading that manages summer without shutting out winter.

Flat river-flat sites and steep bluff sites are different projects. Latrobe, Spreyton and the Don Valley bring their own soil, drainage and access conditions. All of it gets priced at feasibility stage.

Home builders serving Devonport, Latrobe and the Mersey

We build across Devonport, East Devonport, Spreyton, Latrobe, Port Sorell and the Don Valley, run from our Launceston headquarters about an hour and a quarter down the Bass Highway — close enough for genuine supervision rather than occasional visits.

Our certified passive house team is the largest and most experienced in Tasmania, and our work has earned 26 state and national building awards including the 2026 HIA Australian GreenSmart Home of the Year. On an exposed northern coastal block, that building science is not a luxury — it is the difference between a house that is comfortable and one that is merely heated.

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.
