Extensions- 30 Sep 2025
Overall, I’m very pleased with the work Marin has carried out for us and I’m currently in the process of instructing him to do more work. Marin built a high spec cedar shed for us with electrics and plumbing, some brickwork and laid composite decking. Marin came across, honest and reliable, which in itself is rare. He was on site most mornings to make sure his tradesmen were on the right tracks. Like with a lot of these things there were some issues along the way and I was highly impressed by Marin’s ‘no quibble’ approach to rectify any problems. I myself have a high attention to detail and am quite indecisive (nightmare client) and Marin was happy to work with me with changes to the project without incurring extra costs.

I hired Valentin for our job of removing an arch as well as widening a hatch and then re-plastering. I am so glad I did! He was a courteous and reliable worker. Very flexible with timings and honouring our requests. He was very neat and tidy too. His price were fair and he did a superb job to a high standard.

We initially hired Michael to convert a bathroom into an office. After meeting him and discussing our longer-term plans, we quickly felt confident moving forward with him on much wider renovation works across the property. Michael worked closely with us throughout the entire process—from early ideas and structural planning through to execution. He consistently provided insightful, practical advice that added real value. His ability to anticipate issues early not only prevented problems but also helped us save money by refining the plans to maximise our goals and avoid unnecessary costs. Michael’s broad knowledge and skill set were hugely beneficial on a project of this size and within a tight budget. He made the process far less stressful and, at times, genuinely enjoyable. He kept me informed and involved at every stage, which gave me a great deal of confidence in both the quality of the work and the decisions being made throughout. Michael helped us renovate every corner of our four-bedroom maisonette in West London—from bathrooms and structural opening-up works to a full kitchen renovation, hard landscaping, flooring, and carpentry. The list goes on. His wide skill set and depth of knowledge were truly impressive and exactly what we needed, particularly as we chose to stay closely involved in the renovation rather than hiring a larger construction and project management company. We genuinely don’t feel we could have made a better choice. It’s not always easy to find a builder who is reliable, honest, and trustworthy, so I feel very fortunate to have worked with Michael. I would recommend him without hesitation and will absolutely continue to work with him on future projects, big or small.

Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.

Extensions- 11 Jul 2024
I recently had the pleasure of working with Pajtim on a large project, and I couldn't be happier with the results. Pajtim is incredibly friendly, level-headed, and trustworthy. He kept to the agreed quote and consistently updated me on the progress. He understood my difficulty with planning and financial challenges and showed great attention to detail throughout the project. Although there was a long snag list, it was understandable given the project's size. The garden is still to be completed, but I'm glad I chose him. I highly recommend Pajtim for any building work.

We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.
