The Green Marmot Capsule Hotel offers fully equipped rooms in a Tiny-house-format for networkers, digital Nomads and travelers. With its minimalistic timber design, it is a condensed Boutique Hotel in the old city center of Zurich. How to transform a concept developed in Japan in the 1970s? Is it acceptable to ask guests to take their shoes off at the entrance? The client's aim was to design a place where many people can stay overnight and still get privacy. A place that relates to the image of Switzerland and embodies ecological values. At the beginning of the planning process a schematic diagram deals with functional and cultural aspects and determines the floor plan. The name Green Marmot refers to the habits of this alpine dweller. The choice of natural materials and colors take up the characteristics of his outdoor living space. The retreat into each private sleeping capsule takes place through a sequence of rooms dealing with narrowness and width, light and shadow, new and old of the existing building. The project is also a contribution to an urban redensification. With reduced personal space requirements, shared functions and by using the infrastructure of the city.
