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. - Pippa

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. - Richard

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. - Ben

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! - Graeme

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. - Gratien
