Excellent initial consultation and advice
Excellent initial consultation and advice I recently had an online consultation with Vasi regarding alterations to the steps leading to our home. From the outset, he was extremely professional, friendly and knowledgeable. He took the time to listen to our circumstances, understand our concerns and discuss various options for making our entrance safer and more accessible. What particularly impressed me was the detailed follow-up email, which included helpful design suggestions, estimated costs and information about possible grants and financial assistance that we weren’t previously aware of.Job location: ME1RMichelle CResponse from RCB Design & Build Contractors
Thank you, Michelle, for such a kind review. It was a pleasure helping you explore safer, more accessible options for the steps and entrance to your home.

Whether it's access improvements, extensions, lofts or refurbishments, we're happy to help homeowners across London and Kent plan with confidence. We look forward to hearing from you when you're ready. Anyone considering a project is welcome to contact us at www.rcbGroup.co.uk. Kind regards, Vasi J., & RCB Group Team

A Stress-Free Experience with Beautiful Results
We are extremely happy with the work completed on our entrance hallway. The team was very professional, reliable, and delivered the project on time with excellent quality. We were initially worried after having a bad experience with workers in the past, but they completely changed our expectations. They treated our home with great respect, kept everything clean and tidy throughout the project, and left the space spotless when they finish. We couldn’t be happier with the final result and would highly recommend them. We will definitely use them again for future projects. Thanks Anca and Costa!Job location: SE16Response from RCB Design & Build Contractors

If you're looking for clear communication and a schedule that's stuck to, I'd highly recommend!
We're currently halfway through a rear extension and loft conversion with RCB Design & Build, and so far I'm really pleased with how the project is going. From day one, communication has been exceptional - I've been kept in the loop on every single decision, with daily updates on progress across the project. If you're looking for a team that's big on communication and committed to keeping your project on schedule, RCB Design & Build are the ones to go with. Highly recommended, I'll update this review once the project is complete!Verified reviewerJob location: WD610 Extensions / Conversions

Bathroom removal and fitting
Vasi and co did a great job removing the two old student showers and joining them together to make a single bathroom in our house. The work was done to a high standard, but what stood out was the communication. They gave an update of the work performed at the end of each day and we're very responsive to message. This was appreciated as it made me a lot less anxious about the work being done.Verified reviewerJob location: SE8RKeir G10 Extensions / Conversions

Conservatory rebuild
" I had a lot of problems with my conservatory, I.e cracked walls and dropped floor. I contacted RCB Design & Build, could not have chosen a better company. They were so helpful, explaining and outlining the reasons for my problem. They completely rebuilt from the base upwards, very hardworking, friendly and professional. Anca was on hand to oversee the progress of work and answer any questions I may have had. I can thoroughly and truly recommend this company for any kind of building work.
