My wife and I recently bought a house that needed complete renovation including ground floor extension and loft conversion. JPF Clarke took on all the work and we were left extremely satisfied with all the work they’ve done.JPF Clark provided a turnkey service, handling every aspect of the renovation, from structural enhancements to solar panel installation. Julian was actively involved throughout the project, coordinating with tradespeople and external providers such as furniture and kitchen suppliers which alleviated a lot of the project management from us. Julian’s meticulous eye for design and symmetry made a significant impact on the overall outcome and design of the house.I highly recommend JPF Clarke for any type of work big or small as you’ll be in trusted and reliable hands.

JPF Clarke Construction and their team came and redid my driveway, and put in a new set of coping stones on my flat roof. Both jobs done so professionally and quickly. Excellent communication, great clear up. Couldn't have asked for a better experience. Now two years on and everything still works brilliantly - so the job has proved to be a good one. I would use these guys again in a heartbeat and highly recommend them

I am extremely pleased with the work of Julian and his team. They completed a full refurbishment of my flat in St John’s Wood including both structural work, plumbing, new kitchen, bathrooms, custom cabinetry, interior architecture and design, etc. have never come across a builder with such attention to detail and high quality output, they don’t cut corners like other builders I have worked with in the past. Plus a pleasure to work with and reliable and reasonably priced. Would definitely recommend.

JPF Clarke did two small projects for us - renovating a small bathroom and then redoing our kitchen/living room, removing an internal wall. They were helpful when first thinking through our ideas - making suggestions regarding design and materials but also being mindful of our budget. The work was done within the timeframes set out, and any snags dealt with promptly. They may not be the cheapest you can find but the care and quality they demonstrated was excellent and reassuring throughout a sometimes daunting process.

We engaged JPF Clarke last year to undertake a major project. We wanted to change the existing configuration of our flat to make better use of light and space available.Now that the works have been completed, we are absolutely delighted, and feel that it was definitely worthwhile.JPF Clarke worked closely alongside us all the way and understood what our final vision was. The architect whom we spoke to initially recommended them for our project. They were reliable, courteous and accommodating to our daily living needs (we were on-site during the project).We were kept informed along the way of what was happening, and any additional costs - inevitable in a project of this nature - were explained and kept to a minimum.The project manager Alan was onsite nearly every day and we were able to discuss the progress with him as it happened.We were impressed particularly by the professionalism and health and safety elements as we needed two large RSJs and we felt confident that we were in safe hands – the borough surveyor who came to oversee the works at various stages was clearly familiar with JPF Clarke’s work.Overall, I would be happy to recommend JPF Clarke for their professionalism, value for money and courtesy.

JPF Clarke have taken my tired 1930's end terrace house and utterly transformed it with extension works this summer 2019. They are an utterly phenomenal building company. Everything on their website about working with the client and exceeding client expectations is true in our experience. My wife and I are absolutely delighted with the final result. This was the first time we had undertaken such a major project and from start to finish we felt we were in safe hands. We could go to work each day safe in the knowledge everything was being taken care of. We have appreciated the utter professionalism, dedication of everyone involved, and the meticulous attention to detail and oversight that is part of the JPF Clarke experience.
