We have worked with Alex and his team at Swift Conversions Ltd twice now—first for a house extension and then for a loft conversion and general refurbishment —and we wouldn’t hesitate to choose them again for our next project. From the moment we received the quote to the final completion, Alex was incredibly communicative, reliable, and always had a can-do attitude. Despite the challenges of fluctuating prices in the market, he delivered the project within budget and stayed true to his word. His professionalism and trustworthiness are second to none. If you’re looking for a builder you can rely on 100%, Alex is the one to go to. Highly recommended!

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

Extensions- 8 Sep 2016
We hired Stone cbm to build our rear extension in Feb 2016 and the job finished on time in April. If there were a best builder award, the winner would be Jas. He is not your typical builder; his communication and execution skills are second to none. He listened to all our requirements like a friend and provide solutions like a pro. We are pleased with the finish. The project is just about on budget and on time, and could have been finished earlier if not for the other tradsman we called in to do other work causing delays. We had all sorts of problems with all the other tradesman and Jas was always there to give us a helping hand. In hindsight, we should have hired jas to do our other work as well as the extension to reduce all the stress. Project managing is much tougher then we thought especially when most of the tradesman out there simply do not care about their reputation at all (even the ones with many good reviews on mybuilder). Jas on the other hand is extremely organized and highly reliable. We would recommend Jas and his team wholeheartedly to anyone and looking forward to working with him again for our next project.

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.

Joinery & Cabinet Making- 16 Dec 2022
I'm so happy with shelving that ozzy and his colleague made. Ozzy took the time to understand want I wanted (floating alcove shelving) provided a clear and comprehensive quote, and kept me updated on completion of the shelving in his workshop. On day of installation, the guys were lovely and friendly, they went the extra mile in dealing with floors and walls that aren't at all straight, and the finished result blew me away, it's transformed the space completely. Such a pleasure to deal with, would highly recommend and i would definitely use them again in the future.

Plastering- 16 Mar 2020
Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects.

Restoration & Refurbishment- 9 Sep 2021
The original job for a bathroom renovation turned into a much bigger job. Raphael and his team ended up helping design and renovate the bathroom, bedroom, living room and hallway. The team helped us source all the materials including underfloor heating and an incredibly intricate mosaic tiled floor in the hallway. They provided practical advise about what was best for the space, what would work within our budget and what would be easy to live with. For example, the team installed underfloor heating in the living room using wood effect herringbone ceramic tiles which would help get the maximum efficiency out of the underfloor heating whilst giving us the wooden flooring look we desired. Raphael and the team were excellent throughout delivering high quality work and we were more than happy with the final results. I would highly recommend Raph and his team.
