Discover London’s Exciting New ‘Smile’ Attraction

‘The Smile’ at the London Design Festival

Presented at this year’s London Design Festival, ‘The Smile’ represents a remarkable collaboration between the American Hardwood Export Council (AHEC), architects Alison Brooks, and Arup engineers. This landmark project is crafted entirely from cross-laminated American tulipwood, showcasing its strength and versatility.

Cross-laminated timber (CLT) is an engineered timber that can be used to make the walls and floors of entire buildings. It has a layered construction with wood fibers turned at right angles in each layer, creating a panel with equal strength in both directions.

About the Design

The curved, tubular timber structure measures 3.5 meters (11.5 feet) high, 4.5 meters (14.8 feet) wide, and spans a length of 34 meters (111.5 feet). This innovative design represents the first-ever ‘mega-tube’ made with construction-sized panels of hardwood CLT.

‘The Smile’ is made from just 12 massive tulipwood panels.

Brooks states, “CLT is going to open up a whole new world of possibility. It reveals the potential for buildings to be entirely fabricated in wood.” This statement emphasizes the sustainable and innovative nature of this construction method in contemporary architecture.
