  Small family run business. Have close to 20 years of experience in building industry. Specialise in custom builds and custom carpentry work like staircases, kitchens and built in wardrobes built from scratch. Our building journey had started in London where quality really matters and a high end finish is always expected. We want to deliver that same high standard in south wales and build our reputation based on quality of work. At beginning of 2019 as our property portfolio grew and have also seen an opportunity to offer our services and knowledge locally in Swansea and surrounding towns.

  Bathroom Fitting- 18 Feb 2026

  Excellent work from Mike and his team. They kept me informed throughout with regular progress updates and pictures, which I really appreciated. They pay close attention to detail and do the job right rather than cutting corners. As a landlord, I was able to stay completely hands-off and let them get on with it. No chasing for updates or wondering if they'd show up – they were reliable and professional throughout. They started early each day, put in a full day's work, and left everything neat and clean. Would recommend and use them again in future.
