Lou, Your Builder.

With over 20 years of hands-on experience, Lou brings a deep understanding of both structural craftsmanship and fine interior detail.

Trained as a carpenter in the UK, he’s built everything from shop fit-outs to dream homes, and has called the South West of Aus home since 2014. Lou has become a trusted local builder known for his integrity, high standards and personal approach.

Frustrated by poor industry standards, Lou founded Naturaliste Building Co to do things differently, with intent to prioritise quality, transparency and authentic relationships.

    – Gordon Grayson Design | East Bunbury

  • We've used Naturaliste Building twice now for our ongoing renovations. Highly recommend Lou and his team for any building/renovation work. From the initial consultation to the final touches, the team was professional and efficient, and the quality of workmanship superb.

    – Marnie Fuller | Port Geographe

  • Lou has renovated 3 bathrooms for us. Lou is professional, his work is first class and nothing is too much trouble. The photos do not do justice but we thought we should show you some of his outstanding work. We were particularly impressed with the huge decking Lou did for us at the back and front of our home. Lou carried the work out himself and did it in a timely manner where it would normally take twice as long with 4 people! His concentration to the job combined with his outstanding knowledge make him one of a kind. His attention to detail is first class. Lou has great attention to detail.

    – Tricia de Vroet | Yallingup

  • Lou made sure to understand all our requirements upfront and offered great advice on things we hadn’t even considered. He also project-managed specialist trades (electricians, gas plumbers, painters) needed to complete the job. It was a huge effort and we were blown away by his professionalism, eye for detail, and commitment to quality. We remained living onsite during the whole build so were greatly appreciative of how respectful the guys were of our privacy and personal time. Not only is Lou an all-round nice guy to deal with, but he delivered an outstanding level of craftsmanship (far beyond our expectations) and we had a few good laughs along the way. If quality is important to you, we cannot recommend Naturaliste Building Co highly enough.

    – Craig and Tracy Wilson | Yalyalup

  • Lou spent the best part of 18-months heavily renovating a large Yallingup property of ours. His workmanship was of the highest standard, in fact it was quite amazing the end result which he created when he converted a garage with a sloping floor into the most wonderful wood-panelled conservatory with level timber flooring… this was only one of many jobs he did for us. His carpentry skills are quite extraordinary.
