A highlight of the London Design Festival will no doubt be this staircase at the Tate Modern designed by architects dRMM. The design is inspired by the work of artist M.C. Escher who's images of endless stairs are endlessly fascinating.
This “Endless Stair” is made from laminated tulipwood and will give visitors wonderful views over the river Thames, as well as a visceral sculptural experience.
At its highest level, the stair is 7.7m tall and can be walked every day from dawn to dusk. At night, the piece becomes an illuminates sculptural art work.
