GEFFKEN MIYAMOTO creates design environments for Fashion, Art, Corporate and Culture. While respecting conventional and traditional aspects of architecture and interior design, we believe in breaking boundaries.

We feel at home in the world of constructed brand and corporate communications as much as in the world of cultural institutions. As a multifaceted team with roots in Berlin and Tokyo our intension is focused in creating an environment that would touch the subconscious of consumer and occupant. We research, write and tweet and we create ideas and emotions for a world in which ancient rituals and instincts contrast with new technologies and a dramatically transformed environment.


We trust in a combination of sound strategy, an holistic approach and our proven experience in design implementation. No matter if a lighting concept, an art gallery, a logotype or a showroom: design always has to follow function – and our client’s goals. For your ideas and goals we design elegant, user-focused products and solutions.

The GEFFKEN MIYAMOTO network is built on friendship, passion and dedication to the craft of architecture and design.

We create value through the development of individual environmental concepts and experiences. Our sociable, pro­lific and multi-disciplinary struc­ture, with part­ners from dif­fer­ent dis­ci­plines work­ing in the same envi­ron­ment, pro­motes a cul­ture of inter­change that adds tremen­dous value to all creative thinking. As a colourful team of Japanese and German craftsmen and consultants, architects and interface designers, writers and artists, graphic designers and photographers we meet to create unipue ideas and concepts.
