Our Customers

A huge thanks to Mel and his team for their wonderful efforts at our place! They were a great bunch of guys to work with... they became part of the family by the end of the build. They were considerate, clean and tidy and did a great job. Mel did a great job or designing and guiding us on every decision. We love our new space!

Deb MuirDirector | Semitone Music

In 2014 Olsen Construction delivered a major renovation to our house in Castle Cove. From the time we handed the property over to Mel until the work was completed we had a fabulous experience and the quality of the works was first rate. Mel provided excellent service and advice and the Olsen team was very caring and responsive. I can highly recommend Olsen Construction

DanielCastle Cove

We felt comfortable from the moment we met Mel. He understood the plans & we really liked his professional & personal approach. We were not disappointed. It was one of the best experiences of our lives. Mel and his team were punctual, and courteous, and worked hard every day. In no time at all we had the home of our dreams and, as Mel knows, we are grateful to him and his team for all that they did for us. Thank you!

Having done 2 significant renovations with Olsen construction over 10 year period, I have been very satisfied with the results. Mel was involved during the design and consulted with us to handle tricky parts of extending our home. The trades onsite were respectful. We had great foreman on site who managed the job effectively. The project cost could be tracked and was close to budget. No downtime, even on wet days. If you have a significant custom project I can recommend Olsen construction.

Giulio Campobassi

Mel and the team at Olsen Construction did an amazing job with our renovation. Nothing was too much trouble and the finished product has been admired by all our firends and family. I cant recommend them highly enough.
