Client Testimonials

Below are some of the testimonials from our clients:

When we undertook a major renovation and additions project on a fairly large home, we were looking for a Perth building company that could deliver on what we were looking for and to also help us understand the finer details of building that we did not have. From design to delivery Jason and Sam from 383 Design took on the project with a level of professionalism and pride in the quality as if it was their own home and they worked with us right throughout to develop the final product to such an exact specification, which still impresses everyone who visits our home.

The trades that 383 Design engage are a real credit to Jason as they deliver quality across every aspect of the build and they understand that the client is sometimes keen to understand how things go together and that sometimes they change their minds. For Jason there are no limits to the questions he will answer and he is always willing to help you as the client understand the details of the project that can turn it from good to stunning. As a professional builder he has not lost sight of the need for the client to love the final home and this come across in every aspect of his management style. For the finishing aspects inside a home Sam is always there to guide you through selections and shows great patience and humour when even the selection ranges through a wide number of possibilities and availability.

For us there is no-one better than 383 Design in the market for residential construction projects… we were so impressed with the service, quality and commitment we received we went ahead and put 383 Design to work on a medium commercial project for our business. Again high quality, competitive costs, delivered on time and service beyond expectations. We would not use any one else in the future

We recently had some significant extension work done to our house in Iluka by 383 Design and we were extremely happy with the result.

All throughout the build Jason Holl managed the project really well, coordinating all aspects of construction in a very professional manner, with passion and a dedication rarely seen nowadays!


He was completely reliable in organising his workers and the coordination of materials to site, all resulting in the project being completed very quickly, and to a high standard. He has an excellent depth of construction knowledge that adds a real confidence that things are built to a high engineering standard.


Jason has now built two homes and renovated one in our family over the last twelve years and we have no hesitation in recommending him to anyone.
