Restoration & Refurbishment- 2 Oct 2026
Radilina and the Full Circle Renovation team were amazing to work with. They carried out my kitchen renovation, as well as the complete refurbishment of my three-storey house, including reflooring and plastering throughout. From start to finish, communication was clear and professional, and the whole team were highly skilled, reliable and attentive to detail. They also provided helpful suggestions and guidance on materials and finishes, which made the decision-making process much easier, and they completed the installation and work to a very high standard. Despite the scale of the project, they made the whole process as smooth and stress-free as possible. I’m extremely happy with the finished result and would highly recommend Radilina and the Full Circle Renovation team. I would definitely use them again for any future work.

We honestly can’t recommend Orland highly enough. He came in mid job after we got abandoned by some shady builders, and was just fantastic. Built us a wonderful bathroom in under a week - was polite, professional, arrived early and all his work was to a very high standard. Would definitely ask him to help with future projects!

Zen has helped transform our home, we’ve drawn a lot of confidence from his considered approach and thorough work ethic. He’s so far addressed the cause of cracks to exterior walls of our property and has provided lasting solutions. We also asked him to plaster our hallway and update the banisters for us, Zen has done a great job of reinforcing the strength of the original features whilst retaining the property’s character. Very good with pets too. Looking forward to the next project.

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

Kitchen Fitting- 13 Dec 2025
Paulo and team came to help me renovate my kitchen, they've done an amazing job on a very old kitchen with many deeply neglected issues including having been flooded several years ago. Excellent quality of work, very skillful - I am a bit of a perfectionist. They were sensitive to my budget and helped me source the best deals on units and advised me on what worktops to get and always available with advise and guidance that was honed with decades of experience. I felt they took on the job as if they were working on their own house - getting the best materials and work done within the budget. Paulo and team worked very hard and I felt they took care of every little detail, checking with me what I wanted and gave me options while pointing out the pros and cons with patience and good nature. 10 out of 10!

Conversions - General- 9 Aug 2026
Florentin created a new entrance to our house by cutting through an existing brick wall, creating two pillars and laying a path with paving bricks to connect the entrance to an existing path. He did an excellent job, working carefully, professionally and cleanly. Although not specialising specifically in heavy brick work, he clearly knew what he was doing, had the right machinery and had the skills necessary to do the job. Florentin is also courteous and well spoken. I am pleased to recommend him without hesitation.

Extensions- 9 Oct 2018
Arben and his Team are the best builders in north London for my experience in the past. On Time, work hard and work well to ensure that YOU the customer can rest assured that whatever you want to achieve IS done without YOU worrying about the former. I had the benefit of seeing Arben work prior to me taking him on but I have to admit that now all works are complete I cannot fault the quality and Arben competence. Arben clearly has a passion for what he does as a profession and has always come across as the type of builder who will not sleep until his customer is both happy and content. I would use Arben again and I have no issue with inviting those who are considering his services to come and see his work. I had a couple of small issues after the build was done (these are to be expected) and when I asked Arben to come back and address those he did. And these were addressed in both a timely and professional manner. Arben has a wit about him and as a person very easy to get on with. Arben explains what his proposals are and is good at sharing ideas. We had a single storey rear extension done and whilst this was my first project Arben keen and professional intervention was welcomed. Big thank you to you and your team.
