Review by Emina Poljak
on 21st July 2026
"We had plans drawn up for both a loft conversion and a garage conversion, and we couldn't be happier with the service. From the initial consultation through to the final drawings, everything was handled professionally and efficiently. The plans were well thought out, our ideas were listened to, and we were given helpful suggestions to make the best use of the space. Communication was excellent throughout, and the whole process was smooth and stress-free. We would highly recommend their services to anyone looking for architectural drawings or planning advice."
Trader reply: "Thank you for your review. We’re really pleased you were happy with the service and the plans for your loft and garage conversions. We really appreciate your recommendation."
