John Gazis – Director Collins Commercial & Industrial

We have worked with Maison Co on a number of projects over many years and found their approach to be innovative, sympathetic and highly professional. A first class friendly service that we would highly recommend to anyone.

Chris Tsirelas –  Unique Homes

Jim came up with great designs for multiple jobs within our tight deadlines on projects. Jim listens to what you need and gives you his expert advice, he always keeps you in the loop with emails and phone calls and follows with others parties such as councils etc. I would highly recommend him as he has great ideas, always prompt and great to work with.

Breton Fleming

Maison Co provided advice, guidance and designed the extension based on our needs.  Jim was able to navigate us through the complex building approval process and provided documentation and organised the necessary input from other consultants as required.  Overall the project approval was smooth and Jim stayed in touch throughout construction to make sure things were on-track, providing advice as required. Jim’s collaborative approach made the process as pain free as it could have been and ultimately we benefitted from his involvement and attention to detail.
