Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

Extensions- 24 Jun 2017
We had a large piece of work done by Johan and his team. It was a 4m single storey rear extension with new kitchen installation, converting the old kitchen into a downstairs bathroom and utility room, plus other bits and bobs like new boiler, rear patio. We got quotes from a few builders, Home Renovations weren't the cheapest, they were actually towards the higher end. But we went and saw their previous work and spoke to some of their other clients. The work was done to a high quality and the clients seemed to be happy so we decided to go with them. Johan's team are very hard working, professional and polite. Pawel and his team of builders, bricklayers, plumbers, electricians, etc. would turn up before 8am and finish at 6pm working solidly throughout the day. There is Magda as the project manager who keeps you in the loop, and answers any of your questions (which we had many). There is Michaela on the finance side who keeps you up to date with the budget. Our budget went over by 5% with "variations" (extra work or materials) but it was always communicated why and the work wasn't done without our approval. Pawel would give his recommendations but the final word would always be ours. But these things can add up. Overall we were very happy with the build, it was done to a very high standard. They also finished it before time. They said it would take 12 weeks in fact they finished it in 10 weeks which was amazing as you would normally expect these things to go over.
