Custom & Passivhaus Home Builders in Hobart

Building exceptional custom and luxury homes across Hobart and southern Tasmania — from heritage-sensitive city blocks to dramatic sites overlooking the Derwent.

Zanetto Builders builds custom, luxury and certified-Passivhaus homes across Hobart and southern Tasmania. Our southern work includes Bluebush at Blackmans Bay — a certified Passivhaus — plus homes at Sandy Bay, Bellerive, Margate and Howden. Open-book pricing, a 48-hour feasibility, and an award-winning team.

Building your Forever Home in Hobart

Hobart is a city of contrasts — Georgian sandstone and sharp contemporary architecture, sheltered valleys and exposed ridgelines with views to kunanyi / Mount Wellington and the Derwent. Building well here means understanding the city’s heritage overlays, its steep sites, and a climate that rewards genuine thermal performance.

As Passivhaus-certified builders, we craft homes for the Hobart climate that stay warm through the southern winter and comfortable year-round — without the energy bills. From Sandy Bay and Battery Point to the eastern shore, we deliver homes that respect their setting and perform for decades.

Built in Hobart — including a certified Passivhaus

The strongest proof in the South: Bluebush, a certified Passivhaus in Hobart, described by its owner as only the third in Tasmania. Around it, a genuine southern portfolio — Verndene in Sandy Bay, The Curve and Waverley at Bellerive on the eastern shore, Howden to the south, and the Margate Medical commercial build at Margate. From the river suburbs to the channel, we’ve built here.

What building in the South actually involves

  • Steep and view-corridor sites — Hobart’s best blocks are rarely flat; structure, access and retaining are priced into your 48-hour feasibility from day one
  • Heritage overlays — Battery Point to South Hobart, sensitive approvals shape design and program; we plan for them, not around them
  • The climate case — Hobart’s cool-temperate winters are exactly where certified Passivhaus performance pays hardest: warm, dry, and near-zero heating bills
  • Bruny and the channel — building further south? Captains Quarters and Lunalon are under construction on Bruny Island right now
