The gym was designed as a porous building open to the landscape and sky through large glass openings. The envelope is composed of anodized and matte corrugated metal panels. The pleated roofs echo the imagery and aesthetics of the surrounding pavilions and introduce rhythm and colorful vibrations to the façade. The interior is composed of architectural concrete in the base and wood cladding in the upper part. Large mirrored glass windows frame the surrounding landscape. The roof is a transversal unfolding of facets alternating glass surfaces and metal panels.
