Situated in the Sakarya region, 170km east of Istanbul, S2OSB is a pioneering management building of an industrial zone. The interior consists of two separate foyers: one serving offices and one serving the auditorium with 170 seats. The grand canopy allows access on both sides, which provides a semi-enclosed space for larger activities. The conference hall fits inside the solid panels while the inner shell is made of acoustically engineered, geometric, laminated wood panels. The natural stone and wood create a warm atmosphere inside, in contrast to the cold metal exterior.
