KOJA: the sustainable, minimalistic treehouse | Polestar

KOJA is a few things. It’s a micro-space treehouse made of sustainable materials. It’s the 2021 Polestar Design Contest’s honourable mention, created by Kristian Talvitie. And it’s the first contest design that Polestar has built in full scale, in the woods outside of Fiskars, Finland.​ #PolestarCars
