Whether you have a single or double garage, an integral or detached garage we can transform a cluttered space into a new room with endless possibilities. A garage conversion provides the extra space you’ve always wanted to create.

You can choose from a full or part garage conversion to create space and transform the appearance of your home, whilst retaining practicality and the image you wish to present.

With a full conversion the whole space is transformed and the garage doors are replaced with windows, choose a part conversion and you can create an extra room whilst retaining some storage space along with the garage door, the best of both worlds.
