Polestar, the Swedish electric performance car brand, is reimagining sustainable travel with KOJA*, a micro space tree house designed by Finnish designer Kristian Talvitie. The design received an honourable mention in the 2021 Polestar Design Contest. Preparing for the launch of the 2022 contest, Polestar decided to bring KOJA to life. Built in the village of Fiskars, an art and design hub in southwestern Finland, KOJA is the first submission from the Polestar Design Contest to be realised in full-scale. KOJA is part of the ‘House by an Architect’ exhibition during the Fiskars Village Art and Design Biennale, open from May to September 2022.
