Aprop Ciutat Vella Emergency Housing / Straddle3 + Eulia Arkitektura + Yaiza Terré

Gentrification is cruel to the historical centres of cities. Living in a walkable, diverse and well-equipped neighbourhood is becoming a highly coveted luxury. It's necessary to regulate the real estate market and mass tourism, to democratize access to housing in densely populated areas, in addition to multiplying its share of affordable housing, either public or cooperative. But, how to build housing in the developed centre if it is the place where the available space is more expensive and scarce? In a kind of urban dentistry, with what we call Tactical Housing, such as the APROP and ATRI strategies, cities are proposed to fill in the cavities of their built-up teeth. It understands vacant lots, properties that have not exhausted their buildability and even excessively large public spaces as places of opportunity to house residential units that, using modular prefabrication with criteria of urban, ecological and social sustainability, achieve faster execution that is more economic, fair and sustainable than conventional public housing.
