Fujimoto Sou’s pavilion for the Serpentine Gallery, a prestigious annual commission in London, achieves a delicate lightness and synthesises many of the aims of his architectural practice. The structure is a three-dimensional grid made of thousands of slender two-centimetre steel pipes welded together. The orthogonal white lattice uses forty- and eighty-centimetre cubic modules and appears as if it could extend infinitely in all directions. Transparent polycarbonate discs and glass squares inserted in the frame create surfaces for seating or climbing and offer protection from the elements. The resulting formless cloud blurs interior and exterior and challenges typical architectural elements, as benches, stairs, walls, and roofs emerge out of each other, defining a topography. Visitors can climb and inhabit various platforms in an open, fluid manner.
The pavilion highlights Fujimoto’s interest in nests and forests as both metaphorical and formal influences. Nature/Architecture engages a number of dualities that are legible in his other projects, including artificial/natural, simplicity/complexity, and transparency/opacity. Indeed, the multi-level, porous structure echoes many earlier residential buildings, both realised, like the Final Wooden House (2008) and House NA (2011), and unbuilt, such as the Primitive Future House (2001) and the Geometric Forest for the Solo Houses project (2013). The temporary Nature/Architecture clearly demonstrates a key aspect of Fujimoto’s design philosophy: the creation of new relationships between people and space.
