    Our dream loft conversion

    Posted 07 November 2025

    We had a few quotes from different companies before we chose JNA Developments to carry out our loft conversion. From our initial meeting with Justin we instantly felt at ease. Justin is very knowledgable & came up with some great ideas for the best way to use the space. Justin’s team were very polite & conscious that we were still living in the house while the work was being done. All the work was completed to a very high standard & we would highly recommend them. We’re doing an extension next, which JNA will be carrying out.

    Full extension and renovation of ground floor period property in Kingston

    Posted 22 November 2023

    We feel constantly lucky that we were (by chance) recommended Justin and his lovely team, and let us tell you now - book him. You’ll regret it if you don’t. We are thrilled with our extension, the finish and the workmanship. We have a young child, a dog that barks a lot and I am the very particular (read pain in the butt) one out of my husband and I, but nothing was too much trouble, they were great with our family, patient and clear about costs and timings. We will be using them again for all our work and we already recommend them to anyone asking. A team like this is hard to find!

    Loft Conversion

    Posted 17 August 2023

    Justin and the team were fantastic, very professional and timely. We had a loft conversion, including new roof and tiles. The results are brilliant. The team are trustworthy and all was completed as quoted. Good company to use for the whole package from architect, structural engineer, planning application to completed build.

    Wraparound extension

    Posted 08 June 2023

    We are very pleased with the wrap-around extension including a much bigger kitchen and dining area which Justin and his team have built for us. One of the first things Justin explained to us was that he could ensure we had a working kitchen for as long as possible. This made such a big difference to us as we were living on-site during the build. He also showed us other high quality jobs which he and his team had created - very helpful. Always very professional, efficient, and very likeable - it was a real pleasure to have them on site and they always cleared up at the end of the day.
