What Klein Dytham Architecture does

Klein Dytham Architecture (KDa) is a Tokyo-headquartered multidisciplinary architecture and interior design firm founded in 1991 by Astrid Klein and Mark Dytham, both graduates of the Royal College of Art who trained at Toyo Ito's office. The practice delivers architecture, interior design, public space, and installation services to a global client base concentrated in luxury retail, hospitality, corporate, and cultural sectors. Its client roster includes Cartier, BMW, Google Japan, Tsutaya, Fender, Sony, Selfridges, Shiseido, and Virgin Atlantic, with project work spanning Japan, London, Los Angeles, Bangkok, and other international markets.

The firm's core product is project-based professional design services billed through commissions on individual buildings, interiors, and installations. Beyond services, KDa has extended into product design through partnerships such as the Doradora modular seating line with Japanese manufacturer Karimoku and Fender Pick Tables, opening a path to licensing and recurring revenue. The firm also operates two ecosystem platforms: PechaKucha Night, a presentation format founded in 2003 that has scaled to more than 1,300 cities, and DESIGNART, an annual Tokyo design festival co-founded in 2017. These platforms function as brand, talent, and deal-flow engines rather than direct revenue sources.

Revenue mechanics are anchored in design fees on commissioned projects, typically structured as a percentage of construction cost or as fixed project fees, supplemented by product collaborations. The firm employs between 11 and 50 staff and has been continuously active for over three decades, accumulating international design awards and high-visibility commissions. Geographic expansion is project-driven rather than office-driven, with international work sourced through the firm's reputation and principal relationships.
