Loft Conversion- 31 Mar 2026
We recently hired Altin to do our mansard loft conversion and honestly, it was a really good experience from start to finish. He was always on time, worked really hard, and his whole team put in a lot of effort every day. Communication was easy and straightforward, which made things much less stressful for us. The project was finished on time as agreed, and we’re really happy with the quality of the work. Altin was also super helpful whenever we had questions and helped a lot with building control, which made a big difference. It’s quite a messy job (cutting through the ceiling and putting in a staircase), but they did everything they could to keep things as clean and tidy as possible, which we really appreciated. Overall, we had a great experience and are very happy with how everything turned out. I’d definitely recommend Altin to anyone thinking about a loft conversion.

Added partition walls and a doorway to modify the entrance to our office area, creating a small meeting room. The work was completed to a good standard and at a time that suited us. Works were completed on time. The quote was 30% lower than what we paid in the end, but I think the result was worth the price.

Latest review:
Martin undertook a comprehensive renovation of my entire house, incorporating rear and side extensions, a loft conversion, and a rear pod addition. The project involved stripping the property back to its bare walls, reconfiguring room layouts, and installing entirely new bathrooms and kitchen facilities. Additionally, Martin oversaw the revitalisation of the garden area. Martin's professionalism and meticulous attention to detail were exemplary throughout the project. I am exceptionally pleased with the outcome of the work. This is not my first collaboration with Martin; I previously engaged his services for a complete house renovation in 2021.

Conversions - General- 8 Dec 2021
We are very happy with Zaza and his team's work on our flat, which included taking down a structural wall and installing a box frame to support the load, and then installing a new kitchen, toilet, floors and wardrobes. They worked diligently and efficiently, and managed to work around supply problems, as well as the challenges of us living in the flat during the works, to ensure the project finished on time and on budget. They communicated well, making sure to understand exactly what we wanted to do while also giving good advice where compromises had to be made, and gave us frequent updates on the progress of the work. We will definitely want to work with them again on our next project!
