Architecture, Building and Structure Design Otto Uno Residential Building and Social Housing by Natalia Ottonello The main mission of Otto Uno's design was to create a Social Housing building with contemporary architecture and a Biophilic Design, with both an environment and social commitment. The studio aimed to create a sustainable biophilic architectural design, where greenery defines the project’s identity. Otto Uno's design, which connects humans, architecture, nature, and the city, proposes a new design paradigm, in which vegetation and living nature must be considered constituent elements of architectural language; enriching the city by improving the quality of life of its residents.
