Tumi Bjartur Valdimarsson is a Reykjavík-based creative director, filmmaker, editor and designer working across film, sound and public space.

In 2023 he founded Brandugla Studio, a multidisciplinary practice focused on environmental and social storytelling. His work often explores the relationship between people, landscape, sound and systems, from documentaries on organic farming and music culture to public design projects centered on geothermal infrastructure, ecology and human connection.

Originally trained as a screenwriter and director at the Icelandic Film School, he later continued his studies at Catalyst Institute in Berlin, where he developed a collaborative and interdisciplinary approach to filmmaking and visual communication. In 2026 he graduated with an MA in Design & New Environments from the Iceland University of the Arts, further expanding his practice into spatial and systems-oriented design.

His projects include the feature documentary GRÓA, premiered in 2024, concert films and documentaries created with Treble Technologies, TENGJA, a geothermal heated public bench developed with Veitur, and FURNATURE, a protective structure for young trees made from Icelandic wood and surplus wool.

Across directing, editing, producing and design, his work is driven by atmosphere, curiosity and a strong sense of place.
