Extensions- 17 Nov 2025
Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

Carpentry- 31 May 2017
Was really impressed with these guys. Helped me order the correct garden door and then went to pick up extra bits when the order didn't turn up correctly, for no extra cost and couldn't have been nicer about it, even though it was a pain for them. Really cheerful and helpful - nothing was too much trouble. Would use them again, for sure.

★★★★★ Highly Recommended! I had an existing 3-bedroom rundown property and contacted multiple builders before meeting Director Mr. Q Nawaz. From our first meeting, I was impressed by his ideas and the fact that Grand Designs could provide all services in-house. Initially, I proceeded only with the planning application to see if what he promised was possible—and YES, he delivered! My application was approved as he assured me. Seeing this success, I entrusted them with the entire construction project, and Grand Designs completed it within just 6 months, despite the challenges of COVID-19. Not only did they build my project, but they also added significant value to the development. I’m proud to have worked with them, and their exceptional work on my St Albans development is now featured in their portfolio. Within one year, the value of my property increased by £500,000—a testament to their expertise! Extremely professional, highly skilled, and very reasonably priced. You don’t need to go anywhere else—Grand Designs is the complete package!

Restoration & Refurbishment- 9 Sep 2021
The original job for a bathroom renovation turned into a much bigger job. Raphael and his team ended up helping design and renovate the bathroom, bedroom, living room and hallway. The team helped us source all the materials including underfloor heating and an incredibly intricate mosaic tiled floor in the hallway. They provided practical advise about what was best for the space, what would work within our budget and what would be easy to live with. For example, the team installed underfloor heating in the living room using wood effect herringbone ceramic tiles which would help get the maximum efficiency out of the underfloor heating whilst giving us the wooden flooring look we desired. Raphael and the team were excellent throughout delivering high quality work and we were more than happy with the final results. I would highly recommend Raph and his team.
