Testimonials

A really excellent design which met our objectives, and has very much enhanced our home. Construction took longer than planned but the team made a determined effort to complete the work in time for Christmas, and were helpful, attentive and pleasant to deal with throughout. The work was completed to a high standard inside and out with great attention to detail and the site thoroughly cleaned and tidied on completion.

Great team to work with. Valter has been very patient with us over a two year period and has helped us all the way with the design, plans and budgeting. It's never an easy process but he and his team have kept it as stress-free as possible.

We commissioned Happy Building to undertake the design of our proposed rear extension. Our requirements were not straightforward and yet Valter and his architect took everything on board and provided us with a range of options. Very professional, good fun to work with and, perhaps most importantly, they listened to what we wanted and also put forward their own ideas. We would thoroughly recommend them.

The project involved relaying the drive, building a new front wall and installing electric gates and lights. Valter and Jenny from Happy Building were great. They kept me informed, discussed changes and were reasonable with their quote and the variations. They undertook the work efficiently and managed through the challenges as they arose. Will definitely use them again.

I wouldn’t hesitate to recommend Happy Building. My project was a two storey extension and complete refurbishment of a house that had barely been updated since the 1950’s. From our opening meeting we built up an excellent relationship with Valter and this continued through the entire build. The work started on time and over a six month project only ran a couple of weeks over the scheduled end date which is pretty impressive. We were lucky to have Brigen as our foreman – he’s hugely experienced and nothing was too much bother for him. I’d be lying if I said there weren’t ups and downs over the course of the build but that’s to be expected; the end result is fantastic and we’re so thrilled to now be living in our dream home. Thank you!

We contracted Happy Building to do a full house refurbishment, loft-conversion and extension. From the start, Valter, Beatriz and the team have been very helpful and understanding of our requirements. The first point contact is with Valter, the MD, which provides reassurance. In addition, he is always ready to answer queries, flexible to our needs and easy to talk to. Furthermore, they provide us with suggestions and recommendations to aid our decision-making. We have just completed the planning stage and are excited for the next steps.

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.

Happy Building carried out a full house refurbishment to high standards. I found them to be punctual, tidy, respectful, quick and very easy to talk to. If anything they are too quick! The work carried out is exactly what we wanted and on a few occasions some alternatives were discussed that were actually better both practically and aesthetically. Highly recommend. They are a pleasure to have around.
