The Residential Space II Project focuses on collective residential facilities. Treatment of private (private) spaces aggregated within an architectural complex. Emphasis on residential spaces. The metropolis as densification in spaces. Collective building installations. The Residential Space Project II comprises the study of various types of multi-family residential buildings from modernism to the present. The relationships between the residential building and the city are verified, considering temporal, social and residential aspects, among others. During design practice, issues relating to conceptualization, interference and spatial occupation propositions are addressed and developed through research, participatory and experimental methodologies. The selection of problematic or abandoned areas of the city for housing projects aims to fill urban voids through residential use, create positive interference in the urban fabric and the consequent appreciation of the area as a whole.
