Architects Sharif Kahatt and Marta Morelli of the architectural firm "K+M Arquitectura y Urbanismo" along with students of the workshop "Taller Urban Lima" of the Faculty of Architecture and Urbanism of the PUCP, present their views on a new approach to public buildings in Lima that responds to the need to provide public spaces and build civility through architecture. The published research and projects were elaborated during the 2011 and 2012 semesters. The proposals for architectural and urban projects presented were designs aimed at overlapping spaces for collective activities, through strategic projects that promoted educational and technical development with the social cohesion, particularlly in the more dense and demanded and most dynamic neighborhoods and commercial areas of Metropolitan Lima: Gamarra, Mesa Redonda and Historic Downtown. These innovative architectures propose new building and spatial typologies for the social and professional development.
