About us

Established in 1993, from a desire to provide high-end residential renovations, Blythe & Watchorn are now multi award winners with an abundance of successful home alterations and ecstatic customers behind us. We’re proud to have earned a reputation for leading the way in Tasmanian home renovations and extensions.

We approach each project with passion and professionalism, and provide clients with a builder to trust and depend upon. Our attention to detail extends beyond our team, to the tradesmen and sub-contractors who are carefully selected as they share the same work standard. We prioritise keeping clients informed and involved from the start of the project to the finish.

At Blythe & Watchorn Builders, we get the small things right; we turn up on time, return phone calls, are friendly and courteous, and work with the least interruption to your household.
Whether it’s a complete renovation, extension, alteration, or your older house just needs some improvements, Blythe & Watchorn are your builders. We’d love to hear from you.
