The “Bird Nest” can be similarly used for residential units. It can be a social interaction space for the residents, a playground for the children or a pleasant and relaxing space for those who want to try gardening. As a civil society initiative, the “Bird Nest” may contribute to the transformation of the built environment. The Nest is designed as much self-sufficient and sustainable as possible, in terms of electricity and water. Hence it can be used as a shelter for those in need of a home, without an extra cost for the residents.
