The Solar Stair is a cantilevered concrete spiral in the centre of the building, with Eduardo Paolozzi’s Black Hole mosaic at the base. The stair itself represents the solar year, with 52 steps cast in concrete with seven strips to produce a total of 365 grooves inscribed on the risers, one for each day of the year.
