What an amazing experience I had with 1st STOP Building Cardiff. Their Cardiff Builders built a rear double extension for me and it was absolutely amazing. The project took 4 months which was what was quoted to me. I am really happy with the work and everything looks so nice. The builders were really friendly and very professional at all times.

I called thebestbuilderscardiff.co.uk and spoke to a very nice person on the phone who asked me a few questions about the job and then I was contacted by a building company that came out and saw me. I accepted the quote and they did the work to a really high standard!

I can thoroughly recommend Cosgrove builders based on the extension that they completed at our house in Bryngwyn Road. They worked very hard, turned up on time, listened to our suggestions and the work was to a very high standard. The extension doubled the downstairs floor space and it was not a stressful build at all. A testament to Lawrence Cosgrove's approach. We are very very pleased with the result. Kind regards, Naveed.
