“I have worked with TDA on many of our residential projects from original concept developments to complex renovations. In my experience of working with TDA, I have found their approach to the design process to be refreshing and open minded, with a delivery that is flexible and supportive.

The team at TDA have tackled all our projects with professionalism and with their utilisation of the latest in CAD technology, they ensure that nothing is left to the imagination.

I have worked with Paul Dowinton on many of our projects. Paul is highly personable, approachable and has an unfettered attention to detail. It is for this reason I chose Paul to design the renovations for my family’s home, the ultimate testament to a good working relationship.”
