The project proposes a review of the alpine bivouac's traditional form of the last century.
The core theme is to build a small and compact wooden space/object, whose dimensions are big enough for refreshing and stay. Because of the small capacity, classical bivouacs are formed just of a sleeping room. In this case the essential functions of living spaces are compressed together in order to find the synthesis of a house reduced on minimum terms.

The space of the micro-architecture is divided in three parts. The first, very small, is the entrance that functions as a filter between the inside and the outside (1), in this space is possible to hang clothes and dry shoes. The second part (2) is the heart of bivouac, which opens to the landscape, where are placed the dining room and the storage under the floor. The sleeping room is the last part (3), an intimate and closed space protected from low temperatures.
