Opportunistic Park(ing): A Distributed Pedestrian Network

Abstract:

This thesis proposes ulterior means of producing public space within the city. 

My research has focused on where the current policy for public space making is ineffective and where there are opportunities to propose alternative strategies in both locating and implementing these spaces. 

This design experiment exploits an economy of means both politically and conceptually to illuminate how policy may be augmented to produce public space that will better serve the city.

Current Practices:

Within cities public space is typically created in two ways; the first method, as with Central Park in New York, develops huge acreages of land, often resulting in the displacement of marginalized groups. The gentrification of the Seneca Village community, located within the bounds of the new Central Park Plan was made possible through the exploitation of policy mechanisms such as eminent domain.

The second method, practiced in the downtown districts of cities such as San Francisco and New York, creates pockets of public space through policy mechanisms that trade public square footage for developer rights. While new development is obligated to make minimal square footages of public space on site, loopholes in city code are often exploited by the developers resulting in public spaces that are inaccessible to the general public due to sectional discontinuity with the sidewalk and mediated by building security. 

4/5. Privately Operated Public Open Space at 835 Market Street:

While this particular POPOS is more generous in area than a typical public space created through new development, the entrance to the building has no indication that this "public space" exists on its rooftop, and it is mediated by the building security, inaccessible after hours and on weekends.

These POPOS, or privately operated public open spaces, are fragmented, limited to locations of redevelopment, and often inaccessible. Rarely are they located in the areas that lack public space, and as such, are indifferent to city wide demographics of high population density and areas of San Francisco with extremely low existing public space percentages. These public spaces do not contribute to the city.

6. POPOS Map: Map of San Francisco showing the location of public space resulting from new development. 

7. POPOS Elevation: These same spaces shown in a compressed elevation of the city.

Based on the limiting qualities of the POPOS I have determined that the metric of success is contiguous public space connected to, and often an extension of the limited pedestrian circulation network of the sidewalk.

8. Elevation: Existing/Desired condition of public space diagram.

Through analysis of San Francisco, specifically looking at population density and existing public space, I have determined that the Tenderloin neighborhood, located just north of Market Street in the heart of the city, typifies this dense condition. At 10% below the city average this neighborhood exemplifies where city policy for public space making has failed. These conditions provides the perfect example of an entrenched community where an architectural design experiment will illuminate how limited policy augmentation can achieve a more productive public space making plan for San Francisco.

Architecture/Policy Precedents:

Precedent analysis provides strategies of architecture as policy; the ability to re-conceptualize space as public, as with Rebar's Park(ing) Day.

Architecture also has the opportunity to provide an open frame work for programming and interaction, as with KGDVS & Dogma architecture's urban strategy for Seoul, Korea.

Lastly, it has the ability to provide a pedestrian thoroughfare providing an alternative to, or extension of the sidewalk, expanding and contracting into a variety of public spaces. These strategies are exemplified in The Highline, by Diller Scofidio Renfro and James Corner Field Operations.

While larger contiguous public space is the desired condition its implementation within a dense urban condition is problematic. This thesis seeks to develop a method that mitigates displacement and gentrification of the dense population that new public space is meant to serve.

In looking closer at the Tenderloin, I have identified abundant existing open space connected at grade to the sidewalk. The abundance of street level parking lots in the Tenderloin present an opportunity to raise the public space up to the city average of 17% without the demolition of existing buildings. 

13. Tenderloin Maps Urban/Neighborhood

14. Distributed vs. Localized public space

Design Constraints:

There are three main issues with parking lots being replaced by public space and relying on the sidewalk as a baseline for pedestrian circulation:

The first is that while these sites do offer an alternative to demolition of city fabric, the function of these parking lots are a necessary stream of tax revenue, especially for the generation of new public space for the city. This requires ulterior strategies to simply absolving them. 

The second issue is that while the existing sidewalk is necessary as an interface between pedestrians and cars, dependence on the sidewalk as a baseline for public activity is a limiting factor of the urban condition this thesis seeks to rectify. 

And finally, the limited scale of these new spaces and their dispersal is at odds with the desired continuous nature of larger successful public spaces that my proposal seeks to develop. 

Design Strategies:

Three design strategies can alleviate these issues. The first is creating these new public spaces one level above street level parking lots. This will not only insure that the stream of tax revenue from the lots will continue, but it will also develop these lots as covered parking, a benefit to the land owner.

15. Section diagrams showing the new surface of public space above street level parking. This surface is then subdivided to provide light and air below, negotiate sectional inconsistencies and grade connections, and provide a higher base level for bridging the street.

The second design strategy is to invert the city block, developing these new spaces as pedestrian thoroughfares through the block. By analyzing site lines to create minimal surgical cuts within buildings one level above grade, connections can be made from space to space within each block creating continuity. 

16. Polemic Image: These images illustrate the considerable difference that can be made by creating a network of spaces that act as pedestrian thoroughfares. In addition, the material choice can add to an intuitive understand of these spaces as "public" as with Rebar's Park(ing) Day (Fig. 10).

17. Site lines are used to create minimal surgical interventions within each block to connect these spaces at the scale of the block adding to the pedestrian network of the sidewalk. 

The third is to bridge between these new spaces to create a totally contiguous condition (Fig. 15). 

These strategies will create a new ground of public space liberated from the car centric city grid but alway connecting back to it. This enables a secondary pedestrian grain to occupy the city through a dispersed, but contiguous network of new public space, creating new sectional adjacencies and opportunities for innovation. While directly adjacent properties may organically develop as a new layering of retail spaces, social services, and the like, the site line cuts are designated as new frontage whose businesses will both activate and foster stewardship of these spaces.

18. Resulting Contiguous Space: Through minimal interventions within and minimal bridging between blocks a new pedestrian network is formed, always connecting back to the existing condition of the sidewalk.

Flexibility within this new ground of public space is required. Changes in topography, maintaining a 15'  clearance above the parking lots, fluctuation in floor hight of adjacent buildings all need to be negotiated. The quality of the parking lots below, conceived of beyond mere service spaces should also be designed with access for light, air, and visual connection to the public space above. These factors have lead me to subdivide this surface into programmable areas that can allow for the necessary sectionally shifts to occur (Fig 15). 

By projecting a structural grid compatible with the parking program below, the surface can be subdivided at multiple scales where each piece can be raised or lowered in section. 

19. Structural Strategy: By developing the programmatic organization of the new public space based on a 10' grid the parking program below will remain functional.

This system densifies at entrances and at the edges for sectional connectivity to the sidewalk and the first level of adjacent buildings and de-densifies in the center for larger programmable spaces desired in public parks. 

20. Grain Densification: The densest areas are where stairs and ramps are used to connect back to the sidewalk.

21. Site Plan: The plan indicates sectional connection to the street where the grain densifies, subsurfaces where programming can occur, and the new frontage produced through surgical site line cuts indicated by the blue line work. The red dashed lines indicating where there is building stock above. Programs B, C, and D are located towards the center of each space and have the area necessary for the listed programs.

A material strategy has been developed based on proximity to Market Street, the major public transit artery through San Francisco. The texture will remain consistent in the North-South axis to give directionality to the intervention and encourage foot traffic to venture further into the neighborhood. The materiality, on the other hand, will transition gradually from textured concrete closest to Market St. where the spaces are expected to have the highest use, to wood decking in the central spaces to give a boardwalk sentimentality, and permeable pavement and lawn system in the Northern extremes for a park-like feel to the spaces where the least amount of foot traffic is expected and where the majority of users will be the residents of the surrounding neighborhood.

Clarification:

An important aspect of the project to point out is that this thesis is not a programming exercise. While possible programs are indicated in the plan and represented in the rendered views, the specific programming occurring at each of these spaces would be developed individually through community outreach and polling with emphasis placed on providing the greatest resource for the local community.

Beyond locating and implementing new public space this thesis seeks to augment policy to require these new spaces as conceptually permanent. So while I am developing the tectonics of the system over the lots as relatively flexible and impermanent, new development of those lots would be required to maintain both the public space and the connectivity of the network.

22. Phasing: The distinct and disparate space would be developed separately as new funding from new development in the downtown zone allowed. As funding is allocated to two or more spaces within a certain proximity, bridging between them would be incorporated into the design process. The system would form "organically" with new development of the street level parking lots having to negotiate the conceptual permanence indicated above (Fig. 22).

23. Exploded Axonometric

24. Axonometric

Sidewalks, new public spaces, and existing parking lots can be integrated into a cohesive system. The resulting cuts through each block create new frontages and adjacencies that foster stewardship and promote successful public spaces.

25. Section Perspective

26. View 1: The experiential render illustrates how these spaces would be occupied and how possible programming of the new subdivided surfaces could play out. It also illustrates the contiguous nature of the spaces, how they bridge existing streets, independent from the car-centric grid, but always providing access.

In Conclusion:

Through these minor manipulations in public policy this thesis shows that architectural strategies have the ability to hijack the developer-centric process of public space making in downtown San Francisco and allow the city to create new public spaces at a per-neighborhood scale. 

Methodologies can be developed through architectural analysis that exploit local conditions while mitigating many negative affects of the new development of public spaces.

Parametric Design

Topic Point 5: 

What is parametric design? Is it the "style" of the future? Is it the key component to an architectural movement that “finally offers a credible, sustainable answer to the drawn-out crisis of modernism that resulted in 25 years of stylistic searching” as Patrik Schumacher proposes in his Parametricist Manifesto? What can computational design offer to a profession already in the midst of a transition, or "crisis of representation" as was repeated during recent thesis presentations? The shift from designing in a two-dimensions to designing in a three-dimensional environment, at least within academia, has questioned many fundamental understandings of how architecture should be represented. Many students produce plans and sections, cut from their 3D designs as opposed to designing in plan and section, while at the same moment there are successful practicing architects that only work in 2D and rarely touch a computer. Is there a lack of understanding and discourse across a "generational gap" in the profession that is only exacerbated by the exponential advancement and appropriation of technology in architecture? How does the implementation of parametric design "play out" in regards to a "formal aesthetic" or "style", mass customization (with regards to both design and production), and/or the scripting of an architecture that will actually respond to parameters, either within the currently static design environment, or even mechanically, after its construction?

By: Sean Stillwell

Parametric design software is just that; software. It is a tool to achieve whatever the designer sees fit within the limits of that tool. It is a medium through which design concepts can be explored, formally or otherwise. Of course, tools lend themselves to "styles" or "aesthetics" but it has been, and always will be up to the designer to either understand and utilize any given tool for both its strengths and weaknesses, or to not fully grasp the utility of that tool and thus be subservient to its tendencies. Designing within a set of parameters, or rule sets, is not a new phenomenon in architecture. What has changed with architecture's appropriation of computer-aided design is the exponential computational power utilized through various parametric software platforms. This allows for greater complexity within the algorithm, the embedment of scripts within parent scripts, and even for the iteration of scripts themselves according to a host of additional parameters, all outputting formal, organizational, and/or even conceptual iterations at an accelerated rate. While parametric design software has made available the exploration and production of exciting and complex geometries foreign to architecture, its potential to revolutionize the profession is not a conceptual one. Instead, this software offers architects the ability to embed design environments with information and/or conceptual frameworks that allow for a mutually determinant relationship between architecture and its context, the ability to advance the mass customization of both design and production, and the ability to script building system controls that actually react to given parameters mechanically, in real time, throughout the life of the building. 

In the article Animate Form, by Greg Lynn, the author begins with the idea that architecture “produce[s] drawings of buildings and not buildings themselves [and therefore] is involved with the production of virtual descriptions” (Lynn. 10). Many of these virtual descriptions are problematic to Lynn in that they are conceived of in stasis, devoid of force and motion. A dynamic alternative is a design strategy that is described by “static coordinates”, where “the virtual force of the environment in which it is designed contributes to its shape” (Ibid. 10). When multiple vectors representing time and force are included design space they can influence the topology of a surface and its ability to occupy multiple positions simultaneously in a continuous form.  Lynn calls this “animate design”, where “motion and force are co-present at the moment of formal conception,” and goes on to describe an “architecture [that] can be modeled as a participant immersed within [the] dynamic flows [of the virtual force of the environment]” (Ibid. 11). By giving “weight” to objects or points that influence the object’s form in this dynamic space, the resulting architecture would be in dialogue with the initial conditions of that design space. This would create a mutually determinate relationship where the resulting architectural intervention has a direct affect on the conditions that influenced the formal design. Lynn's description of "animate design" is a conceptual framework in which parametric design software can operate by scripting parameters into a design environment where those environmental parameters are in constant negotiation with the architecture produced.

In the past time laps techniques have been used to imbed art and architecture with motion. Often form influenced by time and force has been represented as an overlay of numerous static frames as depicted in Marcel Duchamp’s Nude Descending Staircase No. 2. Another design strategy involves “sequential formal operations recorded in the building through colors, alignments, imprints, additions and subtractions” (Ibid. 13). Lynn contrasts these methods of imprinting time and motion on architecture with that of designing in an environment populated by forces. Fixed relationships to program, and the consideration of gravity as a simple vertical force are concepts of stasis that can be limiting to design when simply reinforced or contradicted. Designing in an environment with time and force can transform these assumptions into numerous possible relationships that are lost in the idealized stasis of our current 3D modeling software. “Independent interacting variables can be linked to influence one another through logical expressions… from which either a single or a series of instances can be taken” (Ibid. 14). These types of relationships allow multiple forces to affect multiple points differently, which in turn start to influence each other and the form that they define.

The relationships Lynn refers to are key concept when designing with parametric software. By setting up complex relationships between points based on real and/or conceptual information that are either adjustable, or adjust themselves based on specific criteria, a dynamic system develops that can incorporate design influences like force and time. Parametric Software allows for architecture to explore and understand relationships based on integral and differential calculus that can imbed not only a changing value, but also the rate at which that value is transposed into formal, organizational, efficiency, or conceptual strategies. 

Transposition into a form from these malleable relationships can be arbitrary and problematic if both conceptual and pragmatic filters are not rigorously applied. This contemporary ability to loading form with force and time with the incorporation of parametric software challenge architects “to understand the appearance of these tools in a more sophisticated way than as simply a new set of shapes. … gradients, flexible envelopes, temporal flows and forces” (Ibid. 17). The "globular" forms often associated with parametric design are not characteristic of a style or movement in architecture other than the ability to produce them through the advances in both building construction and computational design. The ability to produce these forms offer a sort of freedom in the guise of possibility, but the success of the architectural concept should be judged by how the resulting design performs given the architects intent. Simply embedding form with motion without a conceptual and boarder-line functionalist rigor can produce an architecture that has traded stasis for irrationality.

This is one critique that can be given to the Parametricist's Manifesto, by Patrik Schumacher, partner at Zaha Hadid Architects and co-director of London's A.A. Design Research Lab, and its descriptions of the Kartal-Pendik Masterplan, Istanbul, Turkey, 2006 by Zaha Hadid Architects. While "irrationality" may be a little harsh, the preliminary issue I will take with the manifesto is the attitude taken in the utilization and explanation of parametric design software. The choice of describing parametric design as a "style" is incorrect. Even calling this technology a movement, which is preferable to "style," is problematic. Schumacher defends his use of "style" as a descriptive term: 

“...architectural styles are best understood as design research programs conceived in the way that paradigms frame scientific research programs. Thus, a new style in architecture is akin to a new paradigm in science: It redefines the fundamental categories, purposes, methods, and innovative course of a coherent collective endeavor.”

While the exploration of parametric design should be an “innovative [and multi-directional] course of a coherent collective endeavor,” paramedic software is a tool. Just as economists have utilized scripting in Excel, the ability perform complex algorithms on multiple data sets and organize results into legible visualizations for analysis, architects can begin to overlay variables such as environmental aspects of site, embedded energies of materials, and/or organizational factors into computational scripts. Priorities, determined by the architect, are placed on each variable and then formal outputs can be analyzed. Understanding the implications of the results and how they are formed is the key element in differentiating parametric design from a movement. Even when a dynamic data set produces emergent (and exciting) results through parametric software, a rigorous understanding is necessary, not only of which specific parameters produced a given results, but also of what their implications are. The selection of initial inputs, the determination of how they are scripted, and a critical analysis of the result(s) are all choices. The trajectories enabled by those choices are delineated by the interpretation of a concept, and the means by which the architect can and should remain in control of the design process. 

That is not to say that the time and resources that Zaha Hadid's office, and more specifically Patrik Schumacher, have invested into understanding these tools are not valuable to the architectural community, but the implementation of parametric design in the Kartal-Pendik Masterplan, for example, expresses the problems associated with either a lack of control, a lack of understanding, or a lack of representation and explanation of using “active tools” like Maya’s hair “diagrams.” In my limited experience with Maya hair “diagrams,” as Schumacker compares to the wool form finding experiments of Marek Kolodziejczyk, the results are at best uncontrollable, nonhierarchical, and un-nuanced. Maya animation platforms are use to produce an effect used in animation, not a rigorous diagram that can be transposed into an architectural and/or urban logic. This particular tool offers a handful of variables that only amplify or deaden the effect of static cling between follicles and control the speed of the process. With a developed script, methodology, and a real understanding of what variables affect which aspect of what result, parametric software should embed each thread with a prescribed logic based on specific parameters. This is a very different experiment then simply running a series of splines through a filter and choosing a particular result that may or may not have matched a preconceived form. In this project there was an opportunity to create a hierarchy amongst the connective tissue between the “adjacent contexts” that could have been rigorously controlled and nuanced within a script, much more so than Maya’s hair “diagrams” are capable of.

While this specific example shows the weaknesses in the limited understanding of a specific tool, the utilization of software outside of the “normal” architectural toolbox is a conceptual step in the right direction. The automotive, aerospace, and even sporting goods are industries that already embed design software with variables like wind resistance and gravity to analyze the performance of their designs. Ecotect and other similar environmental analysis software also begin to address some of the opportunities of embedding contextual information within a design environment, but its analysis is far from a dynamic, mutually determinant design environment. With the incorporation of analytic plug-ins such as Ecotect into open source parametric engines such as Grasshopper or Rhinoscript for Rhinoceros 3D, for example, the vacuum that architects have been designing in could become obsolete. This is exactly why the research at well known firms like ZHA is so important. With larger projects, larger budgets, and greater resources, their research has the potential to further our ability to design with parametric software and develop the knowledge to construct the subsequent products.

The conceptual digestion of an overwhelming cache of real time data, the immediate demand and gratification of the “online,” and the schizophrenic nature of personal, mobile technology can be facilitated through a parameterizing of relevant data banks and utilizing these real-time inputs as field conditions within design environments. In designing within a contextual, albeit virtual, environment, gradients have become the means of describing data-scapes of environmental site conditions and occupation that in turn have augmented architecture's understanding of boarder conditions and transitional spaces. This is not only in regards to a "Semperian" notion of "inside and outside," but also with regards to human comfort, programmatic layout, and systems integration. These subsequent gradient fields call for the customization of our built environment and the means to construct that environment at all scales, from large "formal moves" down to individual components comprising possible emergent conditions. Schumacher describes parametric design allowing architecture:

"Systematic, adaptive variation, continuous differentiation (rather than mere variety), and dynamic, parametric figuration concern[ing] all design tasks from urbanism to the level of tectonic detail… Architecture finds itself at the mid-point of an ongoing cycle of innovative adaptation – retooling the discipline and adapting the architectural and urban environment to the socio-economic era of post-fordism. The mass society that was characterized by a single, nearly universal consumption standard has evolved into the heterogenous society of the multitude… The task is to develop an architectural and urban repertoire that is geared up to create complex, polycentric urban and architectural fields which are densely layered and continuously differentiated.”

I agree with the analysis that society at large, and more specifically the architectural community has moved from Modernism into a pluralistic, "heterogenous society of the multitude" where there is no one defining style or movement. In contrast with modernism, there is a conceptual shift from the ability to control or subjugate nature to a methodology looking to exploit environmental factors at a given site responsibly and improve conditions when possible. The current "retooling" and "adapting" of the discipline that Schumacher is directly referring to is, of course, parametric software, but the tool is one of many means and not in itself an end. Parametric design, devoid of its own agenda, will eventually gain the acceptance of the larger profession and of its clientele through economic means of efficiency where design and production of mass customization in a "post-fordism" era advance in a manner that is mutually determinant. The ability to design through scripts provides the efficiency to design customization that can be at odds with the means to produce it. If that design is deemed economic by another factor such as its material efficiency, for example, then that motivation may be such that the means of production are improved. An innovation in a particular means of customized production may also generate the economic motivation for design to innovate and harness it.

[THEVERYMANY “series” have yet no pretention to be smart as biomimetism or aiming toward new ecologies… there are based on a very simple and straight forward oldschool empiric lab approach trying first to understand existing mathematical/geometrical models as explicit and ordered sets of instruction, learn to replicate them through coding and finally within that process strategize in terms of design…

RECURSION in mathematics and computer science, is a method of defining functions in which the function being defined is applied within its own definition. The term is also used more generally to describe a process of repeating objects in a self-similar way. For instance, when the surfaces of two mirrors are almost parallel with each other the nested images that occur are a form of recursion. (ie wikipedia),

RECURSIVEGROWTH – Generation 1 to 7 (2,4,6 omitted) – is based on a coming back to “Recursion” (ie previous tests on subdivision, etc…) as the ultimo model of periodicity – why periodicity after many non-linear approaches? simple: the last series based on aperiodic tilling or replication were used because of high repetition within its model – therefore whenever one is approaching the concept of repetition its ultimo and endless quest is maximizing it…]

Another key conceptual issues I take with designing within the dynamic, parametric, 3D environment described above is that the incredible flexibility is lost once the production phase is reached. While certain conditions can be iterated and developed as forms, organizations, etc., during design, variables, adjustable or reactive to real time data streams that affect architecture, become static once some if/then statement is satisfied or when a desirable form is reached and the design is then "baked," to use the Grasshopper term. All of the inputs are frozen, whether that may be the reality of the inputs or not. Construction documents are printed and given over to the contractor and construction is underway. What was conceived of as a dynamic architecture becomes a static form when built, whether understood conceptually as a field or object. Of course, there are building systems that remain reactive to human comfort like air conditioning or lighting (an on/off switch or operable blinds), but the very nature of parametric software begs the exploitation of an architecture's ability to react to those same design parameters after construction. While this may seem like science fiction, there are many practices that are exploring just this type of research at all scales. Future Cities Lab is one such practice that is exploring this trajectory and have helped develop a plugin for Grasshopper called Firefly. This plugin interfaces with Arduino an open-source processing language and micro-controller that creates a link between a 3D design environment and a mechanical prototype. These studies, while currently at a relatively small scale can be extrapolated to offer possible applications at a facade or entire building scale. Again, it will be the economic factors that will either allow or hinder the development of this application of parametric design. When the dynamic parameterizing and movement of components becomes cheaper or more responsible than a greater density of material, or some sort of post-construction energy generation technique can outweigh the initial cost/benefit ratio of its implementation, then the innovations of this particular niche become practical. 

Energy Farm in Seoul, Korea [2nd Prize Winner - Seoul Performing Arts Island Competition 2005]
The “Urban Energy Farm” proposes a complex intermeshing of variable interacting agents. Three interacting fields of the ground, the space frame and the sky-pins compose a differentiated yet synthetic landscape that is capable of finely controlling and generating a series of varied environment. Though a synthetic set of parameters, this proposal works to create difference at the micro scale of inhabitation. These fully responsive sets of site systems respond, fluctuate, transform and produce according to environmental or energy needs of program and inhabitation. The parametric tools of design become energetic agents in the conception and activation of urban space.

In my brief 2 years in a Graduate Architecture program, I have been introduced to numerous tools and techniques for design without always understanding the conceptual implications of the forms that can be produced.  Developing a familiarity with the tendencies and limitations of design methodologies as well as the analytic rigor to critique both process and artifact are necessary parallels and even foundations to any design studio. Cultural issues of pragmatism, responsibility, and conceptuality consistently challenge emergent theory and technology and the spatial consequences of using any tool for generative design should be analyzed through specific lenses of contemporary and past culture to determine both their relevance and weaknesses. Parametric modeling, for example, can offer the ability to absorb existing mathematics and scripting into digital design environments where field conditions of data-scapes can be generated and analyzed. It allows for the ability to shift scales from systems to subsystems with seamless transitions through mass customization and can facilitate the design, construction, and/or the operation of dynamic architecture that will continue to mechanically interact with its context, its occupation, or other factors to be determined by the architect. But this technical ability is not a worthy "conceptual framework" or "movement" in architecture. It is a tool, a means to explore how these new possibilities can implement an architectural concept.
