Klein Dytham architecture (KDa) is a multi-disciplinary design practice known for architecture, interiors, public spaces and installations. Established by Royal College of Art graduates Astrid Klein and Mark Dytham in Tokyo in 1991, today KDa is a multi-lingual office with an international reputation and a high-profile client list which includes Google, Tsutaya, Sony, Virgin Atlantic, Nike, Uniqlo, Selfridges and Japan Rail. KDa's built work includes flagship retail stores, restaurants, resort facilities, office fit-outs, houses and private residences. KDa has no stylistic recipe, preferring to work with the client, program and other project parameters to develop a uniquely tailored solution. Materials, technology, and context are all key elements of KDa's design approach, spiced always with an irreverent or surprising twist. For KDa, Tokyo is a constant source of inspiration and creative energy. The Japanese thirst for the new, a sensitivity to material and detail in crafting, and an ever-changing urban environment invigorate KDa's thinking and production. In 2003 Mark and Astrid devised PechaKucha Night as an event for Tokyo designers to meet and share their work – it has now grown into an international network with events running in over 900 cities around the globe, inspiring creatives worldwide. KDa spans east and west, offering the boldness of vision that only an outside perspective can bring.
