How can building disassembly, material harvesting and new housing construction assist in the elimination of concentrated poverty?

The Home Re_Considered studio focuses on housing design and housing implementation strategies that can be employed at scale to deconcentrate poverty. Collaborating with community residents, a non-profit 510c3 Community Development Organization (CDO), a material repurposing center, and job-skill training organization, the verticallyintegrated interdisciplinary studio investigates mechanisms for increasing public knowledge about regionally-specific housing-related issues and developing scenarios for mixedincome development. The objective of the studio is to design a viable single-family infill housing prototype (RE_CON 01) and development strategies for site utilization that can promote inclusive, mixed-income development in urbanized areas where gentrification threatens displacement of low-income residents. The studio explores the relationship between building disassembly, material harvesting, and new housing construction oriented toward the elimination of concentrated poverty. Addressing dramatic shifts in regional housing needs that have precipitated over the past 70 years, the studio utilizes participatory processes to develop viable urban housing strategies that can continue to evolve with regional population dynamics. Developed by a vertically integrated, interdisciplinary team that consists of 4 Fourth Year BArch students, 3 Fifth Year BArch students, 8 MArch II students, 4 Architecture Engineering Construction Management (AECM) students, and 15 students in a collaborating Reality Computing course, the aspiration is that the content represented will aid in the development of thinking and policy related to disinvestment that focuses on inclusion and population retention.

RE_CON 01 RE_CON is a broad housing strategy being developed by the Carnegie Mellon University Urban Design Build Studio and Project RE_ in partnership with East Liberty Development Incorporated. The goal of RE_ CON is to deconcentrate poverty and combat gentrification in Pittsburghâ&#x20AC;&#x2122;s blighted neighborhoods by fostering the development of healthy, mixed income communities. Collaboration since 2017 has led to the development of an economic model which leverages new market tax credits and distributes profits from the sale of market rate homes to stabilize existing residents through rehabilitation projects and retrofits. The project works in tandem with DE_CON, a program to harvest materials through deconstruction which will incorporate job skill training in order to provide individuals access to a living wage and a second chance to sustain themselves. These two programs are inextricably linked and feed into each other as we strive to retain existing residents whilst bringing new community members in to create a socially, economically and environmentally sustainable neighborhood.

Jobs Skills Training

The home employs design for deconstruction strategies by utilizing a standardized four-foot offset stud module which reduces the amount of material waste generated by 20% in comparison to traditional stick-built methods. This framing method will not only allow for less time spent on site and less waste but will also provide an opportunity for job skills training. Job skills training aims to facilitate the development of skills that will enable individuals to earn a living wage. RE_ CON will also reuse and divert material from landfill. Offcuts and returns from TAKTL, a local high-performance concrete panel manufacturer, will be utilized in a rainscreen system creating more opportunities for job skills training and encouraging material reuse.

How can we promote deconstruction over demolition? The studio has focused on the notion of deconstructing blight. The aspirations of deconstructing blight are multi-dimensional; with the concept of deconstruction being probed both literally and figuratively. Literally, the studio has engaged in building deconstruction as a physical operation to harvest construction material consistent with Building Material Reuse Association (BMRA) standards and demonstrate how Zero Waste objectives might be achieved. Figuratively, the studio has operated as a group of design activists to deconstruct pre-existing notions of blight and concentrated disinvestment. The repurposed material used on the RE_CON 01 prototype provides opportunity for job skills training with apprentices hoping to get trained in the construction industry, gaining valuable skills in repurposing material and specialized deconstruction that enable them to earn a living wage.

How can a building envelope represent the goals of an Environmental Charter School?

The Environmental Charter School promises to â&#x20AC;&#x153;foster knowledge, love of and respect for the environment and the will to preserve it for future generations.â&#x20AC;? Through its innovative design for deconstruction, prefabricated timber strategy and overall passive energy focus, the building intends to foster long-term environmental respect. The opportunity to innovate with timber not only pushes the timber industry forward but also allows for the children and the city of Pittsburgh to believe and participate in a more sustainable future. Exposing the structure to the neighborhood and using the open space to articulate visual and physical relationships expresses the honesty of the building. An understanding of how the structure being exposed can begin to integrate into a system and become a poetic flow of integrated structure and systems ties the building together. Encouraging engagement and spurring curiosity, the program, structure and systems try to avoid a sense of spasticity and push concurrently to create a constant sense of movement. The series of interior atriums flow upwards opening up onto each other, suggesting a constant sense of dynamism. The primary structure is constantly pivoting and shifting upwards in altered directions. In a push to promote progressive educational strategies, the curriculum is designed to highlight student growth through three streams: knowing, doing, and being.

How can we build on a positive relationship with water?

By the year 2100, global warming, increasing sea levels and lack of land resources have prompted a shift of inhabitation to the waterfront. Living with a constant state of flooding and inundation is a necessity as well as an opportunity to rethink the housing project, the return to the notion of the commons and the collective. As the city that remains on land becomes over-populated, segregated and too susceptible to the climatic fluctuations of the apocalyptic scenario, we propose a network of water settlements that is not tied to ownership of land, territory or rights; promoting the sharing movement of collectivity for new social and environmental engagements. Imagining the event of a flooded Pittsburgh river edge, extracted environmental data of the Strip District site overlaid with the underground combined sewage network and layers of floodplain are used to identify convergences of storm water overflow. Out of these pollution outflows a network of bioswales is developed for water filtration. The filtered water is extracted underground through infrastructural coils that subsequently develop into a collective housing scheme. The coil essentially operates as a communal vertical street, allowing for program to be plugged in as needed. The vertical street serves as the connective tissue between the plug-ins and becomes the heart of the sharing movement.

Housing Coil

Experiential Axonometric

Along with the resettlement of population comes the need for food & agriculture. As floodwater inundates land, agricultural real estate is lifted above the ground forming a farmscape canopy network between the housing coils. Supported by the water pumped from underground, growing pipes sprawl out from various levels of the coils, connecting to higher grounds on the un-flooded land. While providing new territory for vegetation these pipes also serve to regenerate existing soil. The result is a constant fluctuation of ground between the softscape of the canopy and the hardscape of the existing landform. Housing Coil

LaGuardia Rd and 94th St, Queens, NY Systems Integration Studio. 4 Months Professors Hal Hayes

How do we create a unique sense of place within our increasingly globalized society through a large infrastructural project like an airport?

New York is a city defined by a multitude of scales. Can an airport emulate the city in its degree of complexity in hierarchy and scale? An airport inspired by the urban fabric of New York? Part and whole are interdependent, connection of brain cells allow for conscious to merge as the city blocks of New York allow for the image of New York to thrive. This relationship of parts to whole is not singular, it involves functional order, consistent complexity, and an intricate layering of systems all in dialogue with one another, with its subtle differences forming the whole. As the block, the street, the landmark, the corner store, the person, the light, compose the many pieces of the city of New York, the column, the table, the store, and the skylight follow this dialogue to create a sense of cohesion, control and de-control. Whole and part are able to exist because of their dialogue with hard and soft. Hard as is the city, the built, the manmade, soft as is the person, the green, the light. The backbone of the city of Manhattan, the grid, predominates. The grid has offered a framework for centuries of delirious growth, a skeleton built for uses to evolve and take root. Taking inspiration from the rigor and ration of the Manhattan grid, the grid as a concept is directly manifested into a building. The design concept revolves around the creation of 10 equally sliced division. Four equally located cores support the 10 divisions. As technology related to air travel rapidly advance, the creation of a loose framework for change to actively occur within is needed to guarantee a long life with a loose fit. Within this grid exists a soft disruption, a relief from the grid; the park of the building. The park echoes the relationship between the Manhattan grid and Central Park by acting as a relief space for shared public use.

Structural Module

Structure Designing with progression in technology and aviation in mind, the building is composed as a series of parts. The 10 modular steel framed slices compose the concourse. The modularity of the steel structure allows the concourse to grow or compress as needed in the future. This sustainable approach to structural integration will provide more flexibility in allowing for deconstruction.

The integration of active and passive systems is key to the design and efficacy of the concourse. The building uses its four cores for all of the systems serving the building. The full roof space is utilized for the implementation of evacuated solar tubes, which are around 20% more efficient than solar panels. The roof is also utilized for water collection that will be used as grey water. Around 2,334,400 gallons will be collected per year and will offset almost 40% of the existing concourse water usage. A double skin faรงade on the southern faรงade of the building reduces heat exposure in the summer and allows for passive heating in the winter. The facades are all operable allowing for a stack effect to help circulate air within the building.

How can a library create opportunities for socially equitable community growth?

Novo Commons envisions the library of the future as a library of the people, a communal space for shared and socially equitable community growth. Located at the heart of the Pennsylvania Wilds in Renovo, the first prototyped Novo Commons strives to address the needs of a historically neglected region. The town of Renovo has seen a declining population over the past several decades. 35% of the townâ&#x20AC;&#x2122;s population currently lives below the federal poverty line. This trend is not unique to Renovo; the number of people living in poverty is on the rise nationally, having doubled from 7.2 million in 2000 to 13.8 million in 2013. Novo Commons is a prototypical system, which strives to be the catalyst for increased social and economic mobility through education, training, and community engagement. With the objective of creating a space that addresses the needs of a historically neglected region, four key goals are identified to scale the size of the solution to the size of the problem: growing knowledge, revitalizing jobs, inciting collaboration, and fostering community. Each one of these four areas of focus becomes a part of the whole and are manifested into the learn, create, share, and grow modules. The common modules are intended to be replicable and scalable to allow for a proliferation across the Rust Belt. Each module can be replicated individually as per the needs of specific communities. The Novo Commons becomes a tool for social and economic growth by educating and providing job skills training to individuals in the community. This process can lead to living wage job opportunities in advanced manufacturing and assist in defining the Rust Belt as the heart of advanced manufacturing nationally

Replicability

In order to accommodate for rapid and accessible replication, the building utilizes a Flat Pack Prefabricated Timber Structural System that is predicated on a Design for Deconstruction model allowing for a more flexible and scalable lifespan. The system is completely exposed and aims to make building construction more accessible to the public. Through this economic strategy, social emphasis, and rapid construction system, the Novo Commons aims to replicate across the country and promote equality and prosperity. three streams: knowing, doing, and being.

How does a temporary structure facilitate celestial exploration?

The celestial observation shelter, designed like a Chashitsu Japanese tearoom, is a simple one-story space planned intentionally to be almost uncomfortably small, with little to no fenestration on each of the four walls. This provides an environment for intimacy and conversation while directing attention towards the sky above. The geometry is inspired by ship hulls, which represent adventure and discovery and the sextant, an instrument of maritime navigation and astronomical study; emphasizing the practical use of celestial observation as a means of way finding and understanding our relative presence in the universe. The shelter is designed as an aggregation of attached additional bays linked to oneanother providing opportunity for expansion. The adjustable footings allow for situation in uneven terrains.
