Borge & Saeterdal Da was established in 2001 by Marianne Borge and Kjetil Saeterdal. The office has since then completed one villa, a vacation house, an art gallery and various extensions and refurbishments on existing houses. The firm is guided by an architectural philosophy that espouses "no-nonsense architecture with emphasis on clear ideas and readable forms."

It is also an ambition to work with materials and forms that can withstand the tough climatic conditions in Norway as well as the wear and tear of time and use.
