I recently hired Vithesh for a loft conversion, and I couldn't be happier with the results! He completed the project with exceptional quality and efficiency. The structural floor beams and steel structure were flawlessly installed, and the roof comes with a reassuring 10-year warranty. What impressed me the most was his ability to complete the structural job in just 3 weeks, even though the original estimate was 5 weeks. His commitment to meeting deadlines and delivering high-quality work is truly commendable. I’m absolutely thrilled with the outcome and will definitely be calling him for any future projects in my home. Thank you, Vithesh, for a job well done!

Loft Conversion- 9 Feb 2020
We hired Ivaro to refurb our existing loft - including knocking down a bathroom and taking out the ceiling to extend the space. Rajiv was excellent from the start, very professional, communicative and accommodating. His staff were clearly very experienced and they completed the job quickly without disappearing for a few days. Although they charged more than some of the others who quoted, they were worth every penny. We even asked them to take on a few additional tasks, which again they completed quickly and to a very high standard. We would definitely hire them again and thoroughly recommend them. Thanks guys!

I met Charlie and his team from CM Builders Ltd when they were completing a loft extension and ground floor extension for one of my neighbours. Quotation and budget I was given an estimate subject to drawings as I was on a strict budget that I had to keep to for the build. Charlie was able to help me keep to the budget, both at the final agreed plan and during the build. The project was complex in that whilst it was a loft extension, all of the house was rebuilt. The only thing kept was the external walls and first floor rafters. Whilst the footprint of the first floor was not being changed I wanted to bring it up to current building standards with extra insulation. All of the plumbing and electrics were also replaced including a new boiler. The overall build has come in on budget, save for agreed enhancements that I did not think of at the planning stage and or building regulations such as double ceiling fire plaster boards. There were also items such as the original stairs that I wanted to keep, but Charlie was able to increase the height space in the kitchen making the worktop much more usable for tall people for a larger part of the kitchen. These were suggested to me as potential options as part of the build. Stage payments The stage payments have all been sensible throughout the build and linked to the ongoing work schedule. I have not therefore had any concerns in this regard. Quality of work This was a very complicated build as unlike the ground floor the first and new second floor are “L” shaped. The new 2nd floor included an en-suite and 2 bedrooms. Overall the house has been increased from 2 bedrooms 1 bathroom, to four doubles and 2 bathrooms. The quality of work is excellent and Charlie project manages his team to ensure that they all deliver to a high standard- if it is not done correctlt they do it again, with Charlie spotting any issues. Timeline of build This has generally gone to plan very well. As with any build you have to be realistic as things will happen outside of anyone’s control. When issues have arisen Charlie manages them to a conclusion. Also be realistic if you are having to manage to a tight budget. I had to plan for various stage receipts of cash before I could order the kitchen and bathroom items - make sure you understand how this impacts the build and availability of the work force, recognising that CM Builders have to book kitchen fitters and plumbers. CM Builders are also very helpful in that they have sorted out issues with the brick work of my freestanding garage (nothing to do with the build) and also a neighbour’s wall that could have been dangerous to the public, should it have failed. Conclusion The whole family are very pleased with the outcome and we now have the equivalent of a brand new house that has been built to a very high standard. This has definitely been worth doing both from a valuation perspective and quality of life perspective. I would not hesitate to instruct Charlie and his team again.

Conversions - General- 15 Apr 2026
Luke and Diti are both amazing guys for this project. Honestly speaking they aren't the cheapest quote, but they are definitely beyond expectations. Luke was the only builder who gave a full transparent quote on each item and what was needed for the conversion. Really quick work and good planning because I have 2 cats and they did everything with enough people onsite to minimise the time. Speaking of work, it is good, we kept in communication and they were always happy to explain and adjust slightly according to my concern/question. Leave this comment after the work has been done for few months and everything is solid.
