OSO is a Tokyo-based, architecture and design office with an international perspective. The office was established in 2017 by two partners - Esteban Ochogavia and Michael Sypkens - who formerly worked together at Kengo Kuma and Associates. Both Esteban and Michael have mixed cultural backgrounds and have worked in various offices in Europe and Asia.

OSO’s current work involves both domestic and international projects ranging from office towers and residential developments to luxury retail. Deloitte Summit, a 25-storey office tower in central Vancouver, is the largest project completed by OSO. Yohji Yamamoto, a Japanese fashion designer known for his avant-garde work, is a client as well as a close collaborator.

OSO’s approach to architecture and interior design is complementary as the aim is to create “spatial” experiences, in which the shape and mass produce varying illusions of depth, weight and density. The spaces are therefore characterized by 3-dimensional concepts that can be experienced intuitively by anyone.
