Extensions- 10 Nov 2020
An outstanding team who clearly take pride in their work, it is the little things they think of that make a massive difference. We kept progress notes and any issue discussed and resolved proactively. Carried out some additional work that wasn’t initially quoted and did not charge extra. Shane himself has a fantastic desire to work and deliver. Even through the Covid, with most shops closed, Shane delivered. Would not hesitate to recommend.

As soon as I posted the job Roman contacted me and arranged a visit. Was very punctual, professional and tried to do the best job he could do.

Architecture- 17 Sep 2025
Overall we are happy with the work that has been done, however the whole experience has been soured by the fact that I am still chasing to have the new hot water cylinder properly commissioned almost 2 years after installation meaning I cannot have it serviced and won't be able to claim on the warranty if things go wrong. My home insurance will also not pay out on any damage that may be caused. The other issue is that the two consumer units that were installed have not been labelled so I have no idea which breaker does what, this is a safety concern. My many attempts to contact Mandeep about this have been fruitless, I'm just being ignored.

Extensions- 18 Dec 2019
What a wonderful extension Dan has built for my family and I! Everyone who visits us comments on how lovely it looks - we are extremely happy! From the moment I spoke/met with Dan I knew he would be the builder I would assign for this project. He was friendly, knowledgeable and spent time explaining the work which he would conduct. Dan and his team were always on time and worked hard all day. As promised, Dan completed the job on time and to budget. As with any build, we did encounter some issues, although Dan resolved these without any problems. I would 100% recommend Dan and his team! Give them a try, you'll be pleasantly surprised! Thank you Dan and co.

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.
