Extensions- 7 Oct 2025
I cannot recommend Marcin and his men more. They were immensely helpful throughout a difficult (due to my inexperience and space and budget constraints) and rushed project. They worked to my budget and schedule and delivered to high quality - really an unbelievable job. If you choose them, you are in good hands. They are honest, reliable, and trustworthy.

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.

Extensions- 14 Mar 2024
We had the best experience with Paul and team from the beginning and would 100% recommend him for any job. From the beginning the communication was great, he gave a quote and then didn't chase us for an answer as there was a couple months in between before we confirmed. Once confirmed, he booked a date in. Tim and James turned up at 7.45am every morning, lovely guys who got on with the job and were always polite and friendly. They were also extremely clean and tied up everything as it was before they left. So happy with the finished job and definitely use again for any further work. Thanks Paul, Tim and James!
