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.

The proof is in the record: 23 industry awards, a team of certified Passive House tradespeople, and a certified Passivhaus — Bluebush, described by its owner as only the third in Tasmania. And the philosophy shows up in the paperwork too: open-book pricing on every project, and a 48-hour feasibilitybefore you commit to anything.
