Red building

Imagine what it would be like inside this strange building. What would it be like in the rooms on the corners?

Imagine what happens to the building below ground level? Does this building have a roof?

The building is covered with coloured panels. How many colours are there and how are they arranged?

This is International House at the University of Nottingham, England.
