A towering Escher-like structure made from American tulipwood CLT installed outside Tate Modern for the London Design Festival 2013. Endless Stair was both a sculpture and research project, advancing the knowledge of timber technology and sustainability. 

Equivalent to two-storeys in height, the network of stairs allowed visitors to enjoy the capital from different viewpoints, looking at the art gallery, the Thames River, the Millennium Bridge that crosses it and, on the other side, St Paul’s Cathedral. It also encouraged social interaction.
