Do you have an extension or loft conversion in mind?

Excellent service. The surveyor was on site on time. He was very thorough, and our report was completed in a timely manner. It was everything that we expected.

They helped overcome problems no one else was interested in, without them we would have been stuck, great service from start to finish.

Nikk Fowler

I recently had some structural drawings done by Marsh Design LTD, and from start to finish they were absolutely fantastic. Dave and the team were professional, approachable, and incredibly efficient throughout the whole process. Communication was clear, deadlines were met without fuss, and the quality of their work was second to none. They made what could have been a stressful stage of my project feel smooth and straightforward. I couldn’t be happier with the result and would highly recommend Marsh Design LTD to anyone looking for top-notch structural design work.
