Extensions- 8 Oct 2018
Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family. The design process was completed efficiently and submitted for planning permission, which was granted without a problem. Since then, his team have continued to be helpful and communicative despite my need to delay to the building works due to unfortunate complications with my freeholder.

★★★★★ 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- 16 May 2021
TLC have completed the first phase of the project which has involved a complete renovation and upgrade of the kitchen, bathroom, and rear garden area. A new contemporary staircase has also been fitted. The work has been completed well ahead of schedule, and this is testament to the planning and coordination skills provided by TLC. All of the work has been completed to a very high standard, and a great deal of care has been taken to ensure the minimum disruption to the local residents. We are extremely grateful for the advice and support provided to us leading up to the restoration work and whilst the restoration was underway, and we are absolutely delighted with the final results. Our house has been transformed into a contemporary family home. Many thanks to Bradley, Paul, and the rest of the team at TLC.

Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

Tom and Chris…brilliant work team that go above and beyond with their work ethics and friendly honest approach to the job at hand. Clean and tidy workers that done a fantastic job relaying pipe work where necessary for our sink unit to be placed in our utility room….fitted a very awkward work top in perfectly and plumbed our sink in. They even took the time to hang a wall unit whilst here and we were so impressed with their work that I would not hesitate to recommend these hardworking men! We will be using them again for sure! Thank you once again Tom and Chris!

Extensions- 7 Jun 2026
Zilvinas and the team at Innovate Builders were outstanding from start to finish. We hired them to build our two-storey side extension. Zilvinas was open, professional, and fully committed throughout the project. He was always available to answer questions, offer advice, and guide us through each stage of the build. His team worked hard and delivered a high-quality finish, all while keeping the project on schedule and within budget. As this was our first major building project, we relied heavily on Zilvinas's expertise and guidance. His knowledge, practical advice, and problem-solving skills were invaluable and made what could have been a stressful experience feel smooth and manageable. We are absolutely delighted with the result and would not hesitate to recommend Innovate Builder. As I said it was our first ever big project, we had heard many horror stories but are so grateful to have found Zilvinas and his team.
