Vacant plots in a city are spaces which disrupt the urban tissue and leave it incomplete by throwing into question the use of those spaces. The construction freeze has restricted the habitation of several such vacant plots in San Fransisco city to merely virtual proposals. CONCERNS:The continuous increase of urban modes of transport intensifies the already existing problem of global warming. One of the major constituents of this pollution is carbon dioxide, which is also an intrinsic factor of our breathing system. On any given night in America from 7,00,000 to two million people are homeless. As many as 3.5 million people experience homelessness in a given year i.e. 1% of the entire U.S. population and about 8,42,000 people in any given week. How can one re-think the aspect of existence and existing with population? Our proposal seeks to capitalize on these uninhabited voids by using them to absolve the problem of homelessness through devising an architecture which is facilitated by the pollution generated by the city. WORKING OF THE DESIGN MODULE:The module consists of "packed towers" which inhales impure air and extracts CO2. This CO2 is catalyzed through the solar panels into liquid fuels which is used as energy to operate the latex structure. The solar panels and latex grid suspended from them, both rotate in conjunction to form dynamic enclosures. The latex grid inflates and deflates to form opaque and porous skins of the module. DYNAMICS OF THE MODULE:The solar panels orient themselves to the sun during the day to capture maximum sunshine which results into interesting spatial configurations. During the night, they close to create shelter spaces for the homeless in the city, while the inflated latex skins insulate the interiors making them habitable. Several such modules come together to create a field wherein each module adapts to the various needs of the neighborhood such as spaces for art display, exhibitions, workshops, audio-visual projections and more, by the day. The latex grid changes phase by altering the air pressure. Accordingly the appearance shifts between solid and open, opaque and translucent, from a dense mass to a structure with depth. The closed solar panel grid creates spaces which act as a refuge for the homeless by night. SUMMARY:The module is a strategy inserted in the fabric that addresses the problem of urban voids, pollution and homelessness. In this process, the architectural idea not only fills this shared vacuum, but allows the otherwise redundant spaces to breathe through multiplication, adaptation and sensitization. Such growth is dependent on parameters such as the amount of pollution, the available space and need for accommodating the homeless. As these parameters change, the nature of the module would also perhaps transform its function from refining polluted air (as the depleting sources of bio fuels pressurize the need for more environmentally friendly transport), to other emerging disturbing conditions in the terrain for generating energy. The enclosed space emerges as an important idea of habitation, where one is allowed to define personal spaces during the night by bringing in their "supporting" accessories. The module could assist the users in the pragmatic aspects of storage and preservation of such objects.
