Extension Builder in North Kensington
I charge 60£ for a home visit and quote. This is to cover for my time and the website fee attributed to each add. If the jobs goes trough, this cost will be included in the final price. Hi, I am Flo, your local handyman with a decade plus of experience. Putting up a frame or building up an house extension, I can accommodate both and everything in between. If you have a project in mind i have a decade plus of experience that could come in handy so let’s get in touch. Yours sincerely, Florentin.

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.

I hired Endri for 1 double glazed unit replacement, repair and repaint my wooden windows. He was professional and well mannered from the start. He did a fantastic job on the windows, now they look as good as new from the inside. I'd be happy to hire him again in the future.

Tiling- 24 May 2026
I cannot recommend John from Pacho Create Ltd highly enough. I'm a very particular client with high standards, I was impressed by his care, patience, and professionalism throughout. He clearly takes pride in delivering quality work and paid close attention to every detail. Living in a small flat, I was concerned about dust, but John proactively created a solution to minimise disruption, which I really appreciated. He also gave excellent advice on budget-friendly waterproofing products. We had a challenge with large-format tiles, but John worked closely with me to plan the layout, ensuring a natural, balanced finish. The workmanship is outstanding – minimal wastage, precise alignment, and superb attention to detail. I wouldn’t hesitate to use John again, in fact, I’m already planning to have him back to tile around my bath in the near future. I highly recommend him to anyone looking for a skilled, reliable professional.

We had the most fantastic experience with Sarunas. He was highly professional from start to finish and completed the work to the highest standard. We extended our project significantly once we realised how excellent he was and he has now renovated our whole home over an 18 month period. He was able to guide us through the process and help us make key decisions which made the experience smooth and efficient. He is extremely skilled in all aspects of building, has high attention to detail and is a pleasure to have in your home! I couldn't recommend him higher and look forward to having him back in future to convert our loft!

Plastering- 4 Aug 2026
James was easy to speak to and took the time to answer all of my questions while we finalised the scope of work and contract. His quotation was fair and competitive. The work included replacing the felt on the side extension and dormer flat roofs, as well as applying a silicone render to our Mock Tudor house, all of which was completed to a very high standard. The roof tile repointing, valley leadwork, fascia and gutter repairs were carried out thoroughly, and the roof now looks neat and tidy. A few small items that had been missed from the original contract, but James was happy to take care of them without any issues. James was professional, courteous, and reliable throughout, providing a hassle-free experience from start to finish. His team did an excellent job, kept the site clean and tidy, and completed the work with great attention to detail. I would be more than happy to recommend Ridgewell Roofing & Building Ltd. to anyone looking for high-quality roofing & rendering work.

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!

Restoration & Refurbishment- 26 Aug 2026
Majed was incredible, he came round to assess works 3-4 times before we started, out of his own time to do so. When works started he managed everything end to end, building control, helped us find good suppliers, ran to builders merchants to get materials etc. He always was supportive with doing more, changing electrics, position of plug sockets, changing scope of work. The finishing is incredible, he was extremely reasonable and a lovely guy. We could trust him with the keys to our house which was great! I look forward to working with him and his team again. Thanks a lot Majed, we are very grateful!
