Builders Port Sorell — Custom Coastal Homes

Zanetto Builders builds custom coastal homes at Port Sorell and Hawley Beach on Tasmania’s north-west coast. Our Hawley home was described by experienced owners as the easiest build they’d done. Every coastal home is detailed for the marine environment and delivered open-book, by an award-winning team.

Building your Forever Home in Port Sorell

Port Sorell sits on a sheltered estuary on Tasmania’s north-west coast, alongside the beaches of Hawley and Shearwater — a relaxed, family-friendly pocket that’s growing fast. Homeowners here want practical, beautifully built coastal homes that make the most of the water and the light.

We build custom and Passive House homes throughout Port Sorell and the surrounding north-west, delivering durable, efficient, low-maintenance homes designed for coastal living.

We’ve built here — Hawley Beach

Hawley is a completed Zanetto home at Hawley Beach, right on this stretch of coast — photographed and on this site. Estuary light, coastal exposure, and the detailing that handles both.

Priced properly before you commit

Port Sorell sits about an hour from our Launceston headquarters at St Leonards, which runs every build on this stretch of coast — including the completed Hawley home. The starting point is always the same: a 48-hour feasibility within 10% of the real build cost, priced across more than 90 cost categories, so you know what your Shearwater or Hawley Beach block really costs to build on before you commit. For where genuine custom pricing sits in 2026, see the cost to build in Tasmania guide.

Estuary and beachside homes here reward performance building — sealed, insulated and ventilated properly, they stay warm and dry through the northern winter and cost little to run. Our certified Passive House team of thirteen qualified tradespeople is the largest and most experienced in Tasmania.

Building at Port Sorell, Shearwater and Hawley

Port Sorell, Shearwater and Hawley sit on a sheltered estuary east of Devonport — one of the north-west’s most popular coastal pockets, and a genuine mix of permanent homes and retreats.

We have built here: Hawley at Hawley Beach is a completed, photographed Forever Home on this stretch of coast.

Estuary exposure is gentler, but still coastal. The sheltered water means less wind loading than the open Bass Strait coast, but salt is still present and material selection still has to account for it. Fixings and flashings are where it shows first.

Sandy coastal soils drive footings. Ground conditions around the estuary vary considerably over short distances, and footing design follows the geotechnical report rather than the neighbouring block. It is one of the more common sources of cost surprise on this coast — which is why it goes into the 48-hour feasibility up front.

Holiday homes have a different brief. A house used intermittently needs to stay dry and stable while empty. An airtight, insulated envelope with heat-recovery ventilation does that on almost no energy, and it is the single best investment in a coastal retreat’s longevity.
