Sarah Emilie Müllertz is an architect, creative director, and founder of KINRADEN. Born and educated in Denmark, she holds a master’s degree in architecture from the Royal Academy of Fine Arts in Copenhagen, where her sensitivity to space, material, and proportion was formed.

Before focusing on jewellery, Sarah built a strong career in architecture. She ran her own design studio and later served as Partner and Global Head of Design at Henning Larsen Architects, leading international teams and shaping projects defined by clarity, structure, and cultural awareness.

Her interest in art began early. A committed art collector since her teens, Sarah draws on a broad range of references - from contemporary and classical art to architecture and poetry, shaping a design language that is both informed and personal.

Guided by a belief that responsibility and aesthetics must go hand in hand, she has embedded recycled precious metals and responsible material sourcing into KINRADEN from the outset.

Today, Sarah works at the intersection of architecture, art, and jewellery. Her designs are marked by restraint and precision, balancing minimalist structure with a sculptural sensibility. Quietly considered and intellectually grounded, her work reflects a Scandinavian approach to design; thoughtful, functional, and rooted in long-term value rather than spectacle.
