Latest review:
★★★★★ 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!

Latest review:
After a previous contractor took our money and left our loft extension unfinished, we were devastated and worried about how we would ever get our home back to normal. Then Lewis from Lebelle stepped in and completely turned things around. Lewis was patient, understanding, and incredibly professional. He worked quickly, kept costs under control, and finished the loft extension to a standard we’re so happy with. The stress he took off our shoulders was unbelievable. We honestly can’t thank Lewis enough. If you’re looking for someone trustworthy, skilled, and genuinely caring, Lebelle is the company to call.

Painting & Decorating- 13 Nov 2025
The team did a solid job on our extension. They were on time, kept the place organised, and stayed easy to reach throughout the project. The extension came out exactly as agreed and the finish looks clean. They also took care of a few extra jobs for us, including painting the exterior, laying new slabs in the garden, and putting down new grass. The whole place looks tidy and well put together now. I would be happy to use them again.
