"I’ve recently worked with Design Spec LTD on designing the extensions and refurbishment for my new house, and I couldn’t be happier with the experience. From start to finish, the service and support have been excellent. The team were professional, attentive, and always willing to go the extra mile to make sure everything was moving in the right direction. Their attention to detail and clear communication made the entire process smooth and stress‑free. I’m extremely pleased with the outcome and would highly recommend Design Spec LTD to anyone looking for quality architectural services."

Trader reply: "It’s been a pleasure working with you so far on your home, and we’re glad to hear you’ve been happy with the process to date. We always aim to make things as smooth and straightforward as possible, so it’s great to know that’s been your experience. We’re looking forward to continuing working together and seeing the project come to life."

"The work is not finished yet buy so far they are excellent. This company is wonderful, they took all the worry out of preparing for our extension and the redesigning of our kitchen and bathroom. They organised everything for us - planning, building control and design. The recommended builders and kitchen/bathroom designers and full fitting. Design Spec did everything we asked for without any hesitation. I would highly recommend Design Spec, especially Lauren who was very professional and extremely helpful."

Trader reply: "Thank you for your kind review. We’re really pleased to hear you’ve had a positive experience so far and that the process has been smooth and stress-free. We truly appreciate your feedback and look forward to continuing to work with you on your project."
