What Our Clients say

I’ve worked with Aiden Masterson Chartered Engineer on a number of my projects. He works hard to deliver the perfect design solution from initial concepts to Final detail. His designs are always bright and Fresh and has always a few hidden design gems in the buildings he design. I have found him extremely particular in working to give the best advice and have to say it has always been a pleasure to work with Him toward completion of successful projects.

We employed Aiden Masterson BE and found him ultimately professional towards achieving our requirements.  He demonstrated good judgment, a positive attitude, and excellent communication skills.  Most importantly, we felt he solved problems with careful and detailed study which established our trust in his conclusion.  I can recommend Aiden Masterson and Master Design without any hesitation.

Aiden Masterson and Master Design Came Highly recommend to us when we set out building or dream Home. From the outset he gave us the best advice and showed us the path to achieving our dream home. He thoroughly examined the site and specifically designed our house to take advantage of our setting, aspect and features of our surrounding whilst at the same time designing our home to fit in carefully with our Environment and landscape. Aiden handled all our planning and design work and carefully provided us with an independent selection of vetted, approved builders and he has overseen the project right through the construction stage to flawless completion on time and meeting all our onerous requirements. Without him and Master Design our project would not have been as easy and as successful and we recommend Him all the time for the work we have seen him do.
