The project derives from the search for a better quality of life in the pandemic era, enhancing the life simplicity with respect for nature using ecological and natural systems. The customer of the mobile house is a couple of Japanese professionals: a biologist and an astronomer, driven by the possibility of smart working, decide to live in natural and unspoiled areas in a small mobile home. The house is designed to offer a simple and versatile living comfort with the possibility of moving to different natural areas of Japan being able to face different climates with a highly eco-friendly structure. The interior spaces offer a work station and both horizontal and vertical astronomical observation points.
