    After recently setting up as a sole trader working from home, I was looking to move out of our box room into a larger, more open office, but still work from home. After speaking with Russ and hearing about the Garden Rooms that they’re creating, I decided to use Martindale Windows & Developments to create my new Garden Room, and the result has proved fantastic!

    From the start, Russ, Adam and the rest of the team that Martindale used to make the Garden Room were fantastic. Everything was designed and finished to my exact requirements and everything was left clean and tidy each day after the team were finished for the day. We now have a fantastic office and space to relax within the garden and I wouldn’t hesitate to recommend you to anyone in the future.
