Called Hidaka Ohmu, the organically shaped pavilion is formed from semi-translucent panels of a large seaweed – or macroalgae – called kelp, laid over a rattan frame.
The kelp is treated to remain flexible so that it can be stretched like leather.
It is installed against a window in the conference centre, and is designed to appears like it is growing out of it. A series of nodules protrude from its roof, with others attached further along the glass window.
The Davos pavilion draws on the sinuous Oki Naganode work that Lohmann installed at London's V&A Museum in 2013, which was also made from seaweed panels stretched over a rattan structure.
Visitors can enter the Davos pavilion through an opening in its side, to sit on a bench inside that has views of the snowy Swiss landscape outside.
