Urban Spaces is a minimalist residence located in Bucharest, Romania, designed by ADNBA. One of the most important and problematic aspects of Bucharest is the fast densification of the central area. While the architects believe that density can, and many times must be seen as a form of sustainability, they also admit that the often fragile relationship between habitation within an old neighborhood and the increase of density could many times alter the place and reduce its existing qualities. The project is looking for an appropriate answer to this problem. It tries to mediate between different sizes and densities, in a quite central neighborhood characterized by small streets, long, narrow plots and a puzzle of old and new buildings of all types and scales.
