Custom & Passivhaus Home Builders in Launceston

Crafting luxury custom homes across Launceston and the Tamar Valley — from elegant heritage streets to rural blocks with sweeping northern views.

Zanetto Builders is a Launceston-based custom and Passivhaus home builder — it’s our home city, with 17+ completed projects across the North, including the director’s own award-winning homes. We build across Launceston, Grindelwald, Westbury, Longford, Bridport and the Tamar Valley, open-book and award-winning.

Building your Forever Home in Launceston

Launceston is one of Australia’s best-preserved heritage cities, wrapped around the Tamar Valley and the dramatic Cataract Gorge. It’s a place where fine detail matters — and where homeowners increasingly want the comfort and efficiency of a modern, high-performance home behind a beautifully resolved design.

We build across Launceston and the wider Tamar region, bringing Passivhaus building science to homes that handle the northern climate with ease. Whether you’re renovating a Victorian classic or building new on a valley block, we deliver craftsmanship that lasts.

This is our home city — and most of our portfolio

Zanetto Builders is Launceston-based, and it shows: the bulk of our completed work stands in and around this city. Asgard and The HQ — both the director’s own homes, both reviewed in his own words — alongside The Twins, Marion, NIII, Ecclestone, Tasman, White Hills and more. Out in the valley, Hilhaus at Grindelwald and House on the Green at Westbury; on the north-east coast, The Hide at Bridport. Seventeen northern projects and counting.

What building in the North actually involves

  • Tamar Valley microclimates — frost hollows, river fog and exposed ridgelines each ask different things of a building envelope; high-performance construction answers all of them
  • Heritage fabric — Launceston’s Victorian and Federation stock rewards renovations done with respect and building science together
  • Local trades, local program — our home market means tighter sequencing, faster answers and the subbies we’ve worked with for years
  • Real numbers first — every project starts with the 48-hour feasibility, priced by the team that will actually build it
