What Our Clients Say
Bill Huang
I first found Gavin’s information on Facebook while researching portable home builders. With so many businesses in the market, I visited a few before deciding on 7 Stars Portables—and I couldn’t be happier with my decision. Building a portable home may seem simple, but the real challenge lies in the details. Gavin and his team guided me through the entire process, addressing every unexpected issue along the way with professionalism and expertise. If you’re looking for high-quality craftsmanship and excellent customer service, I highly recommend 7 Stars Portables.

We've been looking at having a granny flat built for visiting relatives & to earn some additional income through short term lets etc. We met with Gavin and the team at the weekend and were incredibly happy at the quality and fitout of the finished article. Gavin's manner and his commitment to our satisfaction is second to none, and we're very excited for our new tiny home to arrive. Would heavily recommend 🙂
