Meet the founder
Michael Trentham founded MTA in 2001 with a simple belief: that great architecture should be accessible, honest about cost, and designed around how you actually live. He leads every project personally, from the first site visit through to handover. Having been in practice for over 25 years, Michael and his team have built a reputation for applying impartial and creative thinking to projects large and small, whether a single piece of bespoke furniture or a large new-build scheme.
“We will not only save you money, we will create natural light-filled spaces that give you pleasure and a sense of place, time and season.” Michael Trentham, Founder
Our approach
We hope, like us, you value design quality and simplicity. We apply the same thoroughness to every project, whether a one-off piece of furniture or a large new build. Our design process is collaborative and bespoke: we listen carefully to your needs and desires, develop your project brief with you, and propose ways to reduce costs while creating a design that increases both your enjoyment and the value of your property.
We are committed to low energy and sustainable design, creating beautiful spaces finished in natural, everyday materials and filled with natural light.

“Having seen the work they had done on another house on our road we were very keen to have MTA work on our extension. They were excellent in turning our ideas into a workable plan which has given us a fabulous new living space. We would happily use these architects again for future projects.”
