Gaz and his team have just completed a conversion of our garage into a home office/den. From our initial conversation throughout the project Gaz was great to deal with. I asked him to take care of the whole project — up to and including decorating. He managed all the organisation of his team and the sub-contractors required: plumbing, electricians, decorators etc. I had a very particular idea of what I wanted in a media wall as the centrepiece of the project. Gaz put me in touch with the perfect supplier who worked with me to design exactly what I wanted. Everyone he brought in did great work — neat, tidy and with great attention to detail for a superb finish. Gaz regularly visited himself to ensure things were on track, and otherwise kept me up to date regularly over the phone. It's clear that it was really important to Gaz that I was happy with things — both as they progressed and in the final outcome. I won't hesitate to call Gaz again and would happily recommend him to anyone who needs property work.

We needed to rearrange the ground floor of our new house to better suit our growing family. GSM construction took down a load bearing wall to create an open plan living family kitchen, and built up a partition wall to separate off a separate snug. We absolutely love it and are very happy with the finished result. Thank you!!!

Gaz and team are all you need for all building works in your home! In my house they worked on areas such as a steel beam installation, tiling, plastering and joinery. Competitively priced, professional, tidy and friendly. Special mention to Matt, a true craftsman and a lovely guy. Would 100{4d150085bb8808f08dd504c68a2d20df9dd7d4b2fb378e37dcfddc6a4e4d4683} recommend.
