I used SWL Building 2016/17, they did a great job and I am still very happy with the work. We had extensive refurbishment as well as a kitchen extension and 2nd story extension. I'd be very happy to answer your questions over a call, just send em a DM & we can organise (sorry... not got much time & typing everything can take ages). Or if you only have a few questions feel free to DM mw with those. But basically, I happily recommend Ben and his team.
