GREEN ROOF: A Networked CommunityThis project is a parametric housing development based on a series of undulating, landscaped, "green" roofs, in which the spatial voids created are infilled with individual housing units for local commuter residents, and driven by an organic district water treatment system. This model was created using 3D printing, Laser-Cutting, and CNC technology, as well as Woodworking Machinery. | PLYWOOD, POWDER-PRINT, 1/16" scale
Strip District | Pittsburgh, PAThe project redevelops a 17-acre site previously used as a rail yard for freight deliveries into the city. The deliveries were brought into the adjacent Terminal, which spanned the whole length of the site to the southeast, and transferred to local truck delivery or an open market. Now abandoned, this project seeks to use the framework of the Terminal to create a new public place for the larger community that integrates with the proposed aggregated housing network.This image was created using Rhinoceros 5 modeling software and Adobe Photoshop.
A Network of Smaller CommunitiesBeginning with these initial sketches of the baseline housing "loop," the baseline geometry of each micro-community is oriented to create a respective communal space that the adjacent residents can take ownership of within the larger public network. This creates a strong dynamic between public and private space that encourages interaction amongst the community.Hand-drawn sketches done by project partner Marina McIntosh.
Baseline Micro-CommunityThe housing network is considered to be an aggregate of this baseline geometry. We studied an array of closed geometries that were translated in 2 axis, and analyzed for the best characteristics of communal space. The surfaces around the perimeter were then manipulated to respond to changing site conditions and housing typologies within, while creating the space framed by the initial baseline closed geometry.These diagrams were created using Rhino 5 and Grasshopper software, and developed in Adobe Illustrator.
Typical Plans and SectionsThe surface manipulation through Grasshopper software created a series of globally unique spaces and opportunities for a variety of housing units. In some cases it can even bring the public realm into the private to emphasize a strong, new dynamic of human interaction.These diagrams were created using Rhino 5 and Grasshopper software, and developed in Adobe Illustrator.
Baseline Micro-CommunityThe first micro-community integrates directly with the east end of the Terminal and is the first interaction between public and private space. This allows the abandoned Terminal to be repurposed and used for future commercial development, as well as district water treatment facilities for the community at large.This model was created using 3D print and laser-cutting technology | BLACK BOARD, POWDER-PRINT, 1/8" scale
Site Aggregation DevelopmentAfter establishing the root of the larger network, the baseline was expanded into an aggregate of micro-communities across the entire site to create a larger public place for the greater community. Reaching into the adjacent urban fabric and culminating out over the Allegheny River, the project seeks to actively integrate with the local neighborhood as a part of its steady growth.This matrix was developed using Rhino 5 and Grasshopper software.
Public or Private?The continuous vertical change in the ground plane creates instances like this where communal spaces can be occupied by both residents and visitors to create a community of mostly public interactions.This drawing was created using V-Ray for Rhino 5 and Photoshop software.
A Renewed Life for the Greater CommunityUltimately, the goal of the Green Roof Network is to become a “renewed life” for the Strip District community. As the network reaches from the greater Strip District and the North Shore via the David McCollough Bridge, it draws people to the Terminal with their wastewater in the form of these green roof paths that form the unique pockets of flexible housing depicted above.This model was created using 3D printing, Laser-Cutting, and CNC technology, as well as Woodworking Machinery. | PLYWOOD, POWDER-PRINT, 1/16" scale
Natural District Water TreatmentAs part of the site development, the heavily polluted river was pulled into the site and filtered through a series of constructed wetlands. It culminates at the west end of the Terminal that houses a plasma-treatment facility to provide potable water to the residents.This model was made using CNC and 3D-Print technology.
Constructed Wetland StudyInitial research began by studying the Allegheny River as a source of highly polluted water, as the Pittsburgh combined sewer system relies on it for overflow in the event of heavy rainfall. Although typically used at a much smaller scale, this study explores leaving the existing sewer-stormwater in place and allowing natural processes to remove the pollutants from the river.This diagram was made using GIS data, AutoCAD and Adobe Illustrator software.
District Water SystemEach of the housing pockets within the network are intended to be self-sufficient. Wastewater is treated as a district system, each with an advanced living machine system within each cluster, and works in conjunction with the large scale constructed wetland system that frames the site. After the wastewater they came with is naturally filtered by both these systems, both residents and visitors complete a journey on our green roof network when they return to the larger community with potable water, a "renewed life" for the Strip District.These diagrams were created using Rhino 5 and Grasshopper software, and developed in Adobe Illustrator.
