U-Build is a Revolutionary Self-build System.

Centred around you

Our aim is to make construction simple, so that anyone can take part. Using only a mallet and a drill, 1-2 people can easily assemble all of our boxes. Using standard connections (supplied), the boxes bolt together, creating a rigid frame for your new space. We supply membranes to protect the boxes if used outside, and it can be clad in a variety of materials.

Permanent yet demountable

Being modular, U-Build is totally demountable and expandable so it can grow and move as you do. Whether you’re looking for a pod, large building or something for indoors, our system allows you to customise your build without limitation, then take it with you if you move locations.

Created with conscience

We care about people and the environment. U-Build was conceived as a low-impact building system suitable for the circular economy, where all parts are fully demountable and recyclable. Many of our solutions do not require concrete foundations, meaning they can sit on the ground with a light touch.

We lend our modular timber boxes to temporary projects, including exhibitions, music events, social campaigns and educational workshops, ensuring materials can be reused repeatedly.
