Builders for those who refuse to compromise.

Zanetto Builders was founded on a simple belief: a home should be built once, built properly, and built to last a lifetime. For over two decades we've crafted custom and luxury homes across Tasmania for clients who value quality above all else.

As certified Passivhaus builders, we combine old-world craftsmanship with modern building science — delivering homes that are beautiful to look at and exceptional to live in: warm in winter, cool in summer, and remarkably efficient year-round.

Every project is a partnership. We work closely with you and your architect through a considered, transparent process, so the experience of building is as rewarding as the home itself.

We are Tasmania's Passivhaus building experts, and the record backs it:23 industry awards, the state's largestteam of certified Passive House tradespeople, and Bluebush — one of Tasmania's first certified Passivhaus homes, independently verified at 10 kWh/m²·yr. And the philosophy shows up in the paperwork too: open-book pricing on every project, and a 48-hour feasibilitybefore you commit to anything.
