Restoration & Refurbishment- 17 Jul 2016
Valter was very impressive on his initial visit with some exciting ideas for the house improvements and we had no hesitation in choosing Happy Building above the other two building firms who quoted. Having signed off on the budget and scope of work, Valter's team of builders arrived. We were hugely impressed with the skill, experience and work ethic of the team; the fact that they arrived early each morning smiling underlined the "Happy Building" epithet; Jarek, the site foreman, had an especially cheery demeanour. The work involved stripping the walls back to bricks, removing walls, reinforcing foundations, plastering, extending the bathroom and removing one bedroom to create a large ensuite bedroom. The latter certainly would not have been done without Valter's vision and patience in explaining how it would look. We were able to deviate from the original plans without any problem which was very important in achieving the final look which we had desired. Valter was very careful in sticking to time and budgets which I had never experienced before with builders. The kitchen, bathroom, two bedrooms, living room and hallways were finished to the highest possible specification within our budget. There were one or two small features which, with hindsight, we would have improved such as door handles and shower fittings, however this was down to us not specifying exactly what we wanted. These are very minor details and a tiny part of the overall picture.

Converting your loft into a beautiful living space may seem like a daunting task, but the results are always going to be worth the painstaking process. The loft conversion procedure does not have to be that difficult; all you require is to hire right people to do the right job.

Extensions- 22 Oct 2018
Choosing MM builders was the best decision we could have made. Initial meetings: They took time to ensure they understand our work. They never complicated matters nor tried to hide things in any fine print and provided us with a estimated schedule and explained we would be kept up to date at all stages. Works: Their knowledge and work ethic is amazing and is reflected in their work. They gave us confidence and built trust very quickly. Always willing to go the extra mile and used their expertise to help us rectify issues or make suggestions in areas we would have never noticed ot thought of. Sam, Ross, Bill & Harry were so pleasant to have around the house. They were very conscious of the 3 young children in the house of which one has additional needs. They minimised disruption which is very difficult when doing major work in a areas and were always friendly and polite. We had no issues in having them inside our property which is very important when completing works taking just over 5 months. They work with specialist tradesman (tiler, plasterer, etc.) who are equally good at their trades. MM were very professional when it came to liasing with Building Control and made sure they were involved and visited at all key points. The aftercare we received was as good as we had received throughout the process. I have no hesitation in recommending MM for any building works. If I was to ever undertake any works in the future, it would be by them and only them.

An outstanding team who clearly take pride in their work, it is the little things they think of that make a massive difference. We kept progress notes and any issue discussed and resolved proactively. Carried out some additional work that wasn’t initially quoted and did not charge extra. Shane himself has a fantastic desire to work and deliver. Even through the Covid, with most shops closed, Shane delivered. Would not hesitate to recommend.

Conversions - General- 9 Aug 2026
Florentin created a new entrance to our house by cutting through an existing brick wall, creating two pillars and laying a path with paving bricks to connect the entrance to an existing path. He did an excellent job, working carefully, professionally and cleanly. Although not specialising specifically in heavy brick work, he clearly knew what he was doing, had the right machinery and had the skills necessary to do the job. Florentin is also courteous and well spoken. I am pleased to recommend him without hesitation.

Extensions- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

Carpentry- 29 Jan 2026
I contacted Ekland and his brother Bes for some light refurbishment. I was so impressed with the work and speed that they ended up doing all the works I intended to do. Starting with latex screed, flooring using LVT system, architraves and skirting boards, installation of 9x heavy duty fire doors, carpets in 2x bedrooms and finally decoration. Prices were very reasonable considering the time and effort they put into installation but not only that, as I am a first time buyer they advised me on design as I didn’t really know where to start. They are honest and reliable, where I tried to save money they said it was not the right thing to do and took additional hours to make something right without a hidden extra. They turn up at 8am everyday and so easy to work with, I left them the keys to my flat and I didn’t need to check in on them at all. If you are thinking to do any refurbishment and are either hesitant or not knowing where to start these are your guys. 5* to Vukaj and thank you!
