Welcome to add-a-room.co.uk a division of Pro-Spec Interiors with offices in Swansea. We cover South Wales, the upper part of the South West and the West Midlands.

We are a family business and work by principles put down by our father when he first started in the building trade in 1951, those principles of quality and respect have not changed and will always be the cornerstone of everything that we do.

Adding a room to your home can be a sizeable investment and we always recommend that you should visit our Buying Advice page for some commonsense ideas that will help you make the right choice.

The add-a-room concept is quite simple; the room we create can be used for whatever you wish.  The possibilities are endless, let your imagination fly and talk to us about how we can help you create your dream
