NAVAJO HOUSING MASTER PLAN PennDesign - Fall 2014 Critics Tony Atkin & Laurie Olin in collaboration with W. Diptee, A. Rahim & Y. Zolotorevskaya This collaborative landscape & architecture studio developed a master plan for the Navajo community of Crown Point, NM. Using a framework of public utilities, my team of four advanced a comprehensive plan to tackle disparate problems ranging from flood mitigation to community building. We strived to provide the minimum number of services needed to allow the people of Crown Point to overcome their inertia. As the only student concentrating solely on architecture, my greatest contribution was the design of the housing units.

Crown Point, part of the Navajo Nation, is a small and isolated town in north-west New Mexico. This isolation is not confined to geography, but entrenched in social & economic difficulties that fragment the residents.

One branch of their troubles is rooted in a long history of American colonialism that subjugated the Navajo and left them neither truely anchored in tradition* nor fully prepared to engage contemporary western culture, while the other is based in enviromental concerns such as water scarcity & the seasonal devastation brought by flash flooding. To deal with such large yet subtle, universal yet intimate problems, we formulated a tripartite plan.

1. Connect Crown Point to tradition, economies, education & the greater geography through simple means such as an expanded bus system & partnerships with outside institutions. 2. Disperse damaging waters by rerouting main storm surges while retaining meaningful amounts to establish natural vegetation and agricultural initiatives.

Nature Trails section perspective by Anooshey Rahim

NATURE TRAILS The nature trails, Crown Point’s first line of defense against seasonal flooding, contain a series of check dams that slow water velocity, reduce erosion during flash flood events, and increase water infiltration for the promotion of a lush and vibrant habitat. The nature trails encourage a commitment to the enviroment that is intrinsic to Navajo culture.

Section Perspective by Yelena Zolotorevskaya


SKATE PARK The skate park, one of the resilient programs bundeled within the linear park, is positioned in a main flood path so that it collects and retains water before it can damage Navajo Technical University and community residences. During most of the year the park doesn’t gather water, but students, tourists, and locals enabling exchange and providing a framework for free recreational activity.

AGRICULTURE Food and its cultivation play an important role in Navajo culture, but flooding and water scarcity make it difficult in Crown Point. Two techniques allow both small-scale plots and land for orchards: the storage of storm water collected in cisterns in the nearby park and the use of grey water.

RETRO-FIT Existing Federal Housing was built with no regard to climate or culture. The master plan makes modest additions, integrating trombe walls for heating and grey water systems. They grey water systems feed to park planters, providing greater privacy through vegetation, then to garden plots. The cost & value of the retro-fit acts as a buy-in for residents to take stake in their community.

DYNAMIC AIR REMEDIATION COMPLEX PennDesign - Spring 2013 Critic Shawn Rickenbacker in collaboration with Arman Hosseini New York Award - D3 Natural Systems 2013

Iron Lung is a building that seeks to be carbon negative & scrub CO 2 from Tribeca, NY while acting as a beacon for the progressive change required to combat Global Warming. Located by the Canal Street Holland Tunnel exit, where over one-hundred thousand cars pass each day, Iron Lung utilizes fluid dynamics to filter the surrounding air. Employing the stack effect, the building enables cross-flow filtration, pulling particulate matter & other pollutants from the air into plant beds resulting in increased vegetation growth and the return of the native wilderness to Manhattan.

Wind is the driving force in the proliferation of pollutants from the Holland Tunnel exit into neighboring communities. By focusing on predictable winds patterns, we leverage their embodied energy to power their own cleaning.

METROFORM A FUTURE MESOTOPIC URBANISM PennDesign - Fall 2013 Critic Peter Trummer in collaboration with Eric Hull

Metroform neither denigrates nor idealizes the future, but sees it as a mesotopia – a possible evolution of the organization of cities and their social structures. Metroform proposes that each architecture is the ground for the next. In this interface of building (private) and building (private), a public realm emerges, creating a continuum between the stratified private spaces of the individual buildings and the resultant, nonhierarchical public space. Within this system, the architecture is no longer the singular skyscraper, but a plurality that reinterprets and reconstitutes the urban condition.


The skyscraper is the vertical manifestation of the typical urban condition. Metroform simutaneously investigates the reorganization of this condition parametrically and sectionally. It speculates on the emergent relationships within this re-envisioned, nonhierarchical, continuum of private and public space.

ARCHITECTURAL MANIFESTATION At instances of convergence, the regularity of private spaces gives way to the inherent unpredictability of public spaces. The discrete moments within these areas are defined by gradients of deformation losing their particular signification as architectural elements.

P.O.P.S. These transitional spaces play a localized role in negotiating between the public and the private realms within a singular architecture. Within the proposed plurality, these spaces mediate and facilitate larger urban relationships such as public thoroughfares, institutions, and cultural or private economies.

NEGOTIATION

ARTS CO-OP & TRANSITIONAL HOUSING

PennDesign - Spring 2012 Critic Annette Fierro

The subject of this project was a Cooperative. Because a co-op’s most important asset is trust, the negotiation of personal space among members is a prime concern. The space must be inclusive, encouraging the mingling of people & ideas, but also allowing individuals to work alone in privacy. To accomplish this two-part goal, the building has open floor plans in which undulating floors & ceilings create an internal landscape of valleys, peaks, & plateaux that delineate the space visually & auditorily without partitioning it.


PERSONAL SPACE Individuals use different methods to maintain their privacy. One aggressive method is for the individual to claim a prominent space so that others must avoid them. A common and passive way is for the individual to move to the periphery of a space to avoid being noticed or interacted with.

SITE PLANNING

TRANSLATION OF INDIVIDUAL RELATIONSHIPS

The proposal of a new Patco stop, connecting New Jersey to Philadelphia’s historic Old City, acknowledges the area’s lack of public transportation, building on its existing job base and notoriety as a tourist destination. The site planning seeks to respect different groups’ needs and individual privacy while promoting cross pollination between them. To execute this I deployed the techniques investigated in the defense of personal space over a speculative mapping of the movement of different groups of people throughout the site and hypothosized a solution to temper the influx of people and activity due to the creation of this transportation hub, as well as the Transitional Housing.

Index, located in Tribeca, NY, a hybrid hotel & residence, incorporates library facilities throughout its circulation & ancillary spaces. Rather than placating the social and economic elite, it seeks to create an inclusive monastic retreat incorporating a public library: the last bastion of civic institutions directly serving the public.


BUILDING FACADE Panels on the buildings façade open to varying degrees in order to alter the amount of light throughout the building creating different levels of intimacy. Panels are widest open when serving public space. They also change orientation to allow the maximum level of natural light in the building.

FOLDING PLATES RIGID PLATE MIURA-ORI STRUCTURE PennDesign - Fall 2013 Instructor Mohamad Al Khayer in collaboration with Andrew Gardner & Eric Hull

This work is an exploration in thick, rigid, origami. The project investigates modes of constructing deployable, rigid plate structures while keeping a single degree of freedom within the system. The wall is fully collapsible and actuated at a singular central point to control the entire folding process. The plates are each constructed of two 3/16 birch panels sandwiching a singular textile membrane that acts as a centralized hinge. Differentiation between beveled and butt-ended panel edges determines the the system’s ridge / valley organization and controls the wall’s ability to collapse entirely.


The Proof is in the Prototype. Investigating different patterns and their spatial capacities meant imposing constraint through the exploration of material logics. On a small scale our team looked at different patterns, controlling them through a series of offset panels that dictated which edges would buckle to form valley folds and which would rise to become mountain folds. At a larger scale, in our Connection Mock-up, we explored how to control the direction and depth of folds through the use of butt joints and varying degrees of mitered joints.

APPENDED SPACE RIGID PLATE MIURA-ORI STRUCTURE PennDesign - Spring 2014 Independent Study w. Mohamad Al Khayer in collaboration with Andrew Gardner & Eric Hull

Appended Space explores the scaling and fabricating of an architectural scale proposal, utilizing the principles explored in our earlier work ‘Folding Plates.’ The work investigates five main goals: Scalability of the system, asymmetric and irregular folding patterns, material construction and fabrication, potential to create, append, and manipulate space through folding, all while maintaining a single degree of freedom.


In the pursuit of assymetric and irregular folding patterns I found the Kawasaki theorem, which dictates that a pattern may be flat-folded locally. Further clash detection was necessary to determine whether it was flat-foldable globaly. Using both the Miura-Ori fold pattern and the Kawasaki theorem, we could iterate quickly through patterns: first drafting them in 2D, then testing for flat-packing with grasshopper.

PORTAL SMART OBJECT PennDesign - Fall 2013 Instructor Carla Diana in collaboration with Michael Kipfer

The concept of the Portal seeks to intensify and elongate the interaction centered around a door, specifically the front entrance of a house. The Portal investigates memory through the opening of a door, using that lens to explore ideas of knowledge and security as well as the discrete but connected actions of approaching, acknowledging, opening, and accepting. As the occupant approaches the door, the frit patterns on the glass slowly align themselves, extending the questioning moment: "Who is it?"


We are thrown into the world from our first home. The threshold to this place of elemental intimacy, familial ties and safety is the front door. It is a portal. When a child runs to meet her parents on their return, she welcomes them back from a world of unimaginable distances and danger. When grown, the child is on the other side of the relationship, but the influence of her first home, first door, first relationships remains. Every door she opens, will be perceived through the lens of her first.

The panels start in the offset position making a closed and private aperture. Embedded with sensors and a motor, the door senses when a visitor approaches, and the panels slowly start to align. The person in the house is alerted and moves to the door. As the panels align, the visitor becomes increasingly identifiable: first a silhouette, then some color, then body features. Finally, as the visitor comes face to face with the door, the frits perfectly align revealing their identity. The privacy of a solid door, and the intimacy of a glass door combined in one.

D-BRIDGE FLEXURE SHELL Point B Design Project Team - Josh Jordan, Jim McKenna, Priyam Mehta, and John Shields with Front Inc, Keast & Hood Structural Engineers, and Urban Technology

Innovation Award: Exemplary use in a Small Firm AIA Technology in Architectural Practice 2015

The D-Bridge (Bridge) is a single-story, single-room, 1200SF building enclosing a path between an existing residence and an Art Gallery. The building is a thickened shell with canted glazing and six door openings—it is environmentally controlled, and it provides both a programmatic link between living and gallery spaces and a series of smaller, more intimate porch-like spaces around the boundaries of the buildings. The doubly curved flexure shell is structurally rationalized into 1000+ sheet metal voxels that act as the design DNA for all other elements.


OVERVIEW The D-Bridge is a yet-unbuilt architectural project and experimental structure that serves as an extension to a private gallery and residence in the Philadelphia area. Our office worked in close collaboration with facade and BIM experts, as well as several other fabricators and consultants in the greater Philadelphia region. We intend to present the Bridge as a case study in small-office technological design and information management. The desire to design and construct a project like the D-Bridge grew from the BIM-like philosophy that serves as Point B Design’s founding ethos. We gained the knowledge needed to design the project through collaboration with contemporary BIM experts, as well as adopting tools and expertise from the burgeoning open-source community around Rhino and Grasshopper. We were thus able to transform our primary tool for geometric control to our organizational system for the entire project. We used it throughout. Everything, from formal experiments to visualization of data, coordination and design of building systems, fabrication management, delivery logistics, and construction scheduling, was managed with the software we used for 3D modeling and drawing.

The geometry of the shell is captured in each individual voxel, so that the overall shape emerges as the bridge is assembled. This is the moment of “embodied intelligence,” where each voxel is derived as an intelligent part. Because each voxel has a place in the shell and its relationship with its neighbors can be indexed and mapped, the order of construction operations need not be held to a linear time-line.

In all, the job is going to require about ~300 sheets of 60”x120” sheet metal. About 200 of these are 16GA and 100 are 12GA.

Since the Design Surface is a relatively fixed surface area – the density of the polygons is also established via an interpretation of ranges of sizes, overall polygon count, and number of sides to each polygon. Sam Rosen

+ 1. PARSING POLYGON OUTLINES

2. AGGREGATION OF FACES

Key points of structural voxel profiles are extracted and reordered creating a triangulated Mesh.

Each corner point’s corresponding triangulated face is grouped with its 3 closest faces, creating 4-faced, 6-sided tiles.

3. OPEN SEAMS

4. FOLDS

Tile’s edges are offset inward to create open seams.

Periphery faces of each tile would be folded so all faces in a specific nodal point - while having different fold angels - would result in the same z-depth.

NODAL POINTS A nodal point is defined by its underlying structural voxel’s center point. All tile faces (a) that share a nodal point (A), irrespectrive of which tile they belong to, are folded along their interior edges, so that their outtermost points have the same z-depth. This means that all fold angles are unique. Depth at nodal points is detemined by the slope of the corresponding structural voxel. The greater the slope -which maxes out where the legs come down to meet their piers- the greater the z-depth at a nodal point. As the shell plateaus at its apex, the concave nature of the nodal points becomes less and less. Sam Rosen

VISUAL VOXELS The primary role of the innermost layer is to create a specific phenomenological experience for users of the bridge. While the structural voxels’ depth was determined by the flexure resitance required, the visual voxels can undulate freely, carving the volume into understandable spaces and providing a substrate for lighting fixtures and air diffusers.

The development of the visual voxels alternated between advancing a digital framework and material studies. The digital framework established relationships between discrete points on individual visual voxels that could be manipulated to create global gradients of change; the material studies clarified where value was embedded in the transformations.
