Extension Builder in Raynes Park
Full Circle Renovation specialises in complete home renovations across London, personally led by our founder from the initial consultation through to completion. Rather than simply providing building work, we take responsibility for coordinating every stage of the renovation, bringing together a trusted team of specialist trades and providing homeowners with a single point of contact throughout the project. Our approach combines careful planning, clear communication and practical project leadership to ensure every renovation progresses smoothly and every decision contributes to a successful outcome. We undertake complete house and apartment refurbishments, extensions, structural alterations, kitchens, bathrooms and bespoke interior improvements, working closely with each client to understand their priorities and create a realistic programme and budget from the outset. Whether you're planning a straightforward refurbishment or a more complex renovation, we believe every project deserves the same level of organisation, attention to detail and personal involvement. We would be delighted to discuss your plans and prepare a detailed quotation for the labour and general building materials required, together with practical advice on the best way to approach your project.

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.

Bathroom Fitting- 5 Nov 2019
I met up with Peter, told him what needed doing and he provided a detailed quote within days. I handed over a set off keys and basically left him and his team to get on with it! This was a time restricted job, he purchased all the material and provided all the receipts. I returned a week later to find the job completed to the highest standard surpassing my expectations. I will definitely be working with Peter again in the future and I would highly recommend him.

We’ve had multiple jobs done by Silviya. The first was a small extension and downstairs and partial upstairs refurbishment with new kitchen and 2 bathrooms fitted. This large job was completed within 16 weeks and looks exactly as we hoped. Given the extent of works we moved out for the build. The second was the construction of an outbuilding and garden redesign (patio and astro fitted). Again the results are great. We lived in during this project and I worked from home without disturbance. The latest has been the re-fit of new windows, front door and fixing the front render. Again, the results are very professional and minimal disturbance while the work took place. Will definitely use him and his team again, should we need any more building work and recommend them to others

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.
