Basically a balcony is designed as an external environment added to housing. From this point of view, the balcony becomes useless in cold season and  unusable in areas of low temperatures. For this reason, we propose this new way of combining outer space with the warmth and functionality that give us indoors.
The choice of the materiality of the external elements such as walls shrinking devices, are the key to generate a multi-functional balance which results in the versatility of the environment.

Primarily, this idea would be highly suitable for small departments, whether for hosting guest, for children to play, or just to relax after a day's work. However, we believe that no matter how wide is the department would be, it is always good to have an additional space.
