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.

BS Loft Conversions are reliable, honest and operate with integrity. I recommend them to anyone who is looking for some building work whether they are big or small projects. They arrive on time, work hard and leave the site clean and tidy. Anxehlo always takes the time to answer any questions we may have and talks us through the process before providing us with all the options available from repair, replacement or re-instatement. As a novice to a huge development, it was difficult to find builders you can trust but, Anxhelo made that process easier, restoring our faith in construction work.

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!

Akash made sure the job was complete exactly how he said it would be, he provided reliability during the installation of our kitchen and answered all questions very professionally. The builders were well aware of the conversations my mother and I had with Akash and so put our mind at ease. The installation itself was very quick (the tear down was very much completed in a few hours) and installed over the weekend. They were very hygiene aware and set up a cover between the kitchen and the rest of our house and didn’t disrupt our home living. They cleaned up before they were gone to very high standards without us even asking them too, all I’m sure is due to Akash’s excellent organisation skills.
