Tony Doyle Associates Ltd is a respected team of CAD technicians and structural design specialists, working across a wide range of commercial, residential, and public sector projects throughout the UK and beyond.

Founded in 1988 by Tony Doyle, the company was built on a clear vision, to be the first name that consulting engineers, contractors, and professionals turn to when they need accurate, efficient, and reliable design and drawing support.

Over the years, we’ve broadened our offering to include all forms of computer-aided design, from detailed manufacturing and patent application drawings to digitised mapping for local councils. More recently, we’ve also extended our services to support local homeowners with planning and extension drawings.

Today, TDA is led by Mike Duncan (Managing Director) and David Brock (Associate Director), who are hands-on with every project, ensuring a high level of quality and attention to detail from start to finish.

Backed by an experienced team, we’re known for our professionalism, technical ability, and our ability to deliver, even under pressure. While technology and client expectations have changed dramatically over the decades, one thing hasn’t: our commitment to getting it right, first time.

Since becoming a limited company in 2001, we’ve proudly worked with more than 125 organisations, including consulting engineers, contractors, and local authorities.

We're also passionate about the future of the industry, investing in the latest software, tools, and training to support the next generation of technicians.

At TDA, our goal remains the same as it was over 35+ years ago: to be the best at what we do.
