Alex and his crew did a fantastic job on my property. They did the work on-time, to budget and to a very professional standard. The work required a wide variety of skills from painting, carpentry, plumbing and electrics. As I was unable to be on site Alex constantly kept me updated on progress with photos and videos. All in all I would highly recommend Alex and his team.

Extensions- 2 May 2018
Tom is a very competent builder, who has attention to details. Tom continuously went out of his way to find ways to meet my requirements, Whenever we had atypical challenge during my extension Tom's default position was "let's find a work around." He was creative and efficient in doing so, and most importantly cost effective, as I was running on tight budget. Fantastic experience working with Tom, he estimated the work to complete in 6 weeks, the work was done 5 and a half weeks and handed over. The works speaks of itself, very urban finish with high level of professionalism. I was almost hands off the project due to work travel, and Tom took care of all the aspects without me being involved day to day and micro manage. He is surely being to be big league builder in no time. I would recommend him whole heartedly.

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.

Restoration & Refurbishment- 12 Jun 2026
Hired to finish off a complete flat renovation - work mainly consisted of painting, some remedial repair work, light carpentry and a snagging list. Whilst Raj and his guy were great at light repairs, handyman and carpentry work (which is the only reason I’m even rating them with stars), their attention to detail and completion of the snagging list was very poor! Despite having discussions with me to rectify things after I showed him examples, the flat is now left with uneven paint edges, drip marks, uneven grouting, unpainted architraves and sloppy silicone work. Whilst they are good at some things, decorating is definitely not one of them, so it’s a shame and disappointing.

Extensions- 30 Sep 2025
Overall, I’m very pleased with the work Marin has carried out for us and I’m currently in the process of instructing him to do more work. Marin built a high spec cedar shed for us with electrics and plumbing, some brickwork and laid composite decking. Marin came across, honest and reliable, which in itself is rare. He was on site most mornings to make sure his tradesmen were on the right tracks. Like with a lot of these things there were some issues along the way and I was highly impressed by Marin’s ‘no quibble’ approach to rectify any problems. I myself have a high attention to detail and am quite indecisive (nightmare client) and Marin was happy to work with me with changes to the project without incurring extra costs.

Conversions - General- 4 May 2025
I Hired Em to do my ground floor reno, which included a garage conversion and remodel of my kitchen where 2 internal walls were removed. Very glad I found Em to do the job. Him and his team was efficient, friendly, tidy and hard working. We encountered obstacles along the process (which is normal for any renovation) but Em gave his opinion, listened and we came to the best solutions. Very happy with the result. Em is a reliable, punctual, knowledgeable, fair, down to earth guy and one of the best if not the best contractor I have hired. Highly recommend. Some before and after pictures.
