Conversions - General- 1 Nov 2019
I was really happy with both the results and the service. I was a little apprehensive about using a person off of this site as I’ve never hired anyone this way, but I’m glad I did, I’m extremely happy, he gave me a good price, he was on time everyday and done the job perfectly, I cannot find a fault. He cleaned up afterwards and left no mess, will definitely be hiring him again. Trustworthy, accommodating and just generally a nice guy. Will deffo recommend

Conversions - General- 22 Feb 2020
Quoted £500 to remove small kitchen wall (<1m wide), make adjacent wall good, and move light switch. Removed wall, moved switch, and kindly moved fridge. Said he'd return to make wall good. On two occasions I arranged to WFH and he failed to show up or let me know. On multiple occasions he said he might be able to do a day but then didn't confirm. He did come by when we weren't in one day to drop wood off to cover wall gaps. One day I arranged for our dog walker to be in at 1. She waited until 3. I messaged Daniel later to ask what happened. He apparently came at 1.20 and waited for 15 mins. I believe he turned up and our dog walker didn't hear door but it's unlikely he tried to knock multiple times over 15 mins, as she was listening for him. Agreed he would finish work in new year. In Jan again failed to confirm days/times on multiple occasions. Finally agreed noon on a Sat. Failed to show up/respond to messages. Eventually got through to him - said his phone was broken. No explanation re why he didn't show up. Agreed he'd come the next Sat but no show again. No response to message or to later one asking if he planned to finish the job. Received a missed call but nothing further. I've left it a month as hoped he would get in contact. It's clear he has run off with £500, leaving giant holes in wall. I work long hours and weekends are precious. I have no patience for someone who has no respect for my free time, or for fact it's not possible to WFH all the time.

Extensions- 28 Oct 2018
We appointed HWB to carry out a full refurbishment on our house, this involved re-gutting the interior and building an extension and loft conversion plus some landscaping in the garden. We spoke to many builders but finally appointed HWB based on their previous projects and professionalism. Appointing builders for any work is always difficult however we are delighted that we went with HWB. Throughout the project they have demonstrated high levels of professionalism, were very organised and worked to very high standards. They were collaborative throughout the whole project and kept us informed at every stage. As the project developed there were some changes made and HWB were flexible and open to new instructions made by us, as well as giving us valuable advice. Farag, Ayoub and the HWB team were always available to answer any questions and provided us with constant feedback on progress as well as identify new solutions to aid the development. They have a great team of workers who work to a high standard and are supervised throughout the project. We made the right decision going with HWB Construction and have no hesitation in recommending them.

Extensions- 29 Jan 2015
PM Building epitomise what a modern day, professional building firm should aspire to be. Transparent pricing, a friendly team working 6, sometimes 7 days a week to get the job done quickly, an eye for detail and very high standard of final finish. All comms and the overall work is run through Bart, who answers to phone, text or email quickly and frequently outside normal working hours. This is ideal if you work during the day and cannot be around to oversee things directly. We also got PM Building to make us a bespoke kitchen, again very high quality and millimetre perfect. If I had to find some negatives, they are not the cheapest company you could find, but there again you get what you pay for; also, we developed a few issues with some retaining walls in the garden, however, they returned when I contacted them long after the work had finished and fixed them! All in all, an excellent, honest and professional company to deal with. I would, and have, recommended them to friends...nuff said.

Conversions - General- 28 Jun 2026
We recently had our detached single garage converted into a fully usable room by Agron and his team, and we couldn't be happier with the result. The project involved replacing the garage door with matching brickwork, raising the roof, installing new windows and a door, insulating the garage, plaster boarding and skimming throughout, and rendering and painting the exterior. The work was completed to an exceptionally high standard. Agron and his team were fantastic from start to finish. They were incredibly friendly, professional and hardworking, completing the project quickly without ever compromising on quality. Communication was excellent throughout, they kept us updated on progress and always made sure we were happy with how the project was proceeding. They were also very accommodating and happy to adapt to any requests or changes we made along the way, making the whole process stress free. The attention to detail and pride they took in their work really shows in the finished result.
