Handyman- 15 Jan 2021
Amazing! Peter came over to help assemble 12 bits of storage furniture for us. This was more than we originally agreed, but he was kind enough to stay and do the extra bits. He was very prompt, very professional, quick and clean worker, easy to chat to and great with the kids (who wanted to help). Highly recommended 👍

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

Painting & Decorating- 17 Jan 2019
We engaged Maciej for a plastering and painting job to repair damage following a roof leak. He also sorted out replacing some of our roof insulation that had also been damaged. Maciej was very efficient and creative in what he proposed. Even though there were unforeseen issues with the job he kept to his original quote. He was tidy and managed to complete the job without putting us to any great inconvenience. Maciej is trustworthy and reliable. I would have no hesitation recommending him.

Based on architect recommendation, we contracted Alain on a private basis to produce structural engineering designs for our home renovation. He undertook a site visit and then produced structural designs to support a large number of elements related to new support beams, lintels etc. These have been iterated with the architect and the process has been very smooth. He was very responsive and nice to interact with. Wouldn't hesitate to recommend as a structural engineer for the type of project we undertook (loft conversion, new pitched roof, new openings within walls and ground floor open plan conversion)

We recently had a loft extension completed along with wooden flooring throughout the house, underfloor heating installation, and a full silicone render — and we couldn’t be happier with the results! The team were an absolute pleasure to work with from start to finish. Their innovative and creative thinking really set them apart — they found smart solutions to challenges and helped us maximise space and style in ways we hadn’t even considered. What impressed us most was their attention to detail and how clean and tidy they kept the site throughout the project. It made a huge difference knowing the work was being done to such a high standard, without the usual mess and disruption. Whether it was a small detail or a big task, nothing was ever too much trouble. No job was too big or small — they approached everything with the same level of care and professionalism. If you’re looking for a reliable, forward-thinking team who take real pride in their work, I couldn’t recommend them more highly!

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.
