The Lower Rio Grande Valley (LRGV) is a transborder region that lies in the floodplain of the Rio Grande/Río Bravo River. The region, which covers four Texas counties and the northern portion of the Mexican State of Tamaulipas, is home to more than 900 colonias on the Texas side of the border. These informal, unincorporated settlements–which house more than 400,000 people–are characterized by substandard housing and a lack of civil infrastructure including sewers, paved roads, and potable water. Many of the colonias flood regularly. This proposal imagines a modular, transitional approach to designing housing and landscape in LRGV colonias. While typical modular housing projects are standardized, prefabricated, packed, shipped, and assembled onsite; the following proposal extends modular efficiencies to the entire site, incorporating landscape, flood control, and canal systems. The holistic, modular approach allows for the flexible growth and decline of the community over the course of one hundred years. Ultimately, the transitional, modular model challenges the adversarial environmental, social, and economic arrangements that exist in colonia developments, imagining a more sympathetic relationship between people, water, and land.

Housing is one of the main themes related to the creation of the city and plays a central role in the definition about how people live together. The development of new living strategies face many different fields of interest: urban planning, economy, social sciences, ecology, sustainability, technology. Architectural composition plays a central role in the definition of how all these matters can coexist and how it is possible to increase urban density and people’s quality of life. The analysis of Louis Sauer’s work on low-rise high-density houses outlines a solution useful for a variety of situations. Higher urban density makes it possible to increase real estate income from investments and, consequently, to increase the architectural quality of the buildings as well as the urban landscape. It gives a tangible answer to many aspects related to urban sustainability making the city more compact, reusing brownfields instead of greenfields, facilitating pedestrian cycle mobility or the use of public transport instead of private cars, and thus helping to reduce urban pollution and the use of natural resources.

While housing could be described as one of the basic forms of architecture and one of its main responsibilities, if not today’s most crucial task, architecture has largely ceased to rethink established forms of living and the politics and economies that surround it. Escaping the pervasive models of profit-based home ownership in the West seems increasingly difficult when housing is dominated by neoliberal market values. Already at the beginning of the twentieth century, however, some architects struggled with similar conditions within the metropolis. Ludwig Hilberseimer’s proposals for new types of living for a new kind of liberated individual are particularly instructive today as they rethought housing as a right, allied with unions in order to rethink its financial models, and learned from activists in the Women’s Movement to question the dominant narratives around heteronormative family structures and domestic labor. In our time of ballooning housing costs, stagnant wages, failed trickle-down economics, and shortages of affordable housing, these urgencies have not lost but only gained momentum.

This essay explores the relationship between a group of design professionals, a community of residents, and a local council in the early stages of the Tustin Estate renewal project – a Master Plan and Phase One Regeneration for a south-east London post-war housing estate. In 2021, the estate’s residents voted in favor of demolishing and rebuilding its low-rise buildings in a residents’ ballot. This essay positions Tustin Estate’s engagement phase as a notable case study for community-led design, providing an overview of London’s introduction of resident ballots in estate development, leading onto the example of Tustin Estate’s ballot, which initiated its engagement strategy. Interviews with key members of the engagement process form the central research to this essay, which explores the role of ballots in estate regeneration; approaches to building authentic engagement; the importance of community ownership; and how listening enables knowledge transfer and creates a blueprint for longevity. The essay defines longevity as the culmination of design and build solutions based on principles drawn directly from residents’ needs, each of which being robust enough to avoid demolition for the long-term.

As the cost of land becomes increasingly expensive, cities are posed to establish new ways of finding sites to encourage affordable housing and housing for people experiencing homelessness. Cities in California and across the US are looking to surplus land, or underutilized publicly owned land, as a resource to develop new housing. One of the obstacles with this effort is the inconsistency of the surplus land parcels. Challenges these sites might be facing can include a lack of zoning, contamination, and a lack of connection to residential or pedestrian-friendly zones. With surplus land presenting a viable option for developing new affordable housing, Architects will be a key component to reimaging these sites to contend with the challenges they face and to integrate this new land use into neighborhood contexts.

A potential answer to the call for a human right to sustainable and equitable housing, water access, and environmental justice may be found in the wings of a desert beetle. This paper presents a housing prototype integrating various water harvesting strategies and biomimetic solutions derived from the Namib beetle. An exploration of issues at the intersection of water access and equitable housing is presented through a literature review that demonstrates how housing conditions, access, and affordability are linked to a lack of infrastructural services, including water, which has subsequent health implications. The paper reviews both passive and active water harvesting opportunities for architectural integration. The paper concludes with a description of the prototype through a case study addressing the housing and water access needs of colonias communities in Texas, and sheds light on water access and housing affordability challenges, proposing architectural and policy strategies to address these issues. The speculative housing prototype integrates water harvesting solutions using a prefabricated kit of parts approach allowing for flexibility and adaptability across various communities where centralized infrastructure is technically or economically not feasible.
