Research for 3D massing strategy of gridded cities Seminar Class, 2012-2013 Spring Semester Instructor: Joan Busquets Solo work Gridded cities actually have the most simply and boring urban form. It is repetitive and accumulative in a simple method. However, the orthogonal grid as an abstract structure is also the most powerful and effective urban approach to deal with complicated spatial and social issues. The orthogonal grid is the most neutral and abstract structure which can provide multiple and diverse possibilities for people to develop the city with their own desires and complicated social rules. That is why the mix-used gridded cities have the similar urban structure, while have totally different street views, building forms and urban experiences.

Six Mix-used Urban Blocks
For different cities in different cultures, the methods to organize and mix multiple functions are also different. It depends on the specific urban density and developing mode. Trying to get a better and clearer understanding of different types of 3D massing strategies for different function spaces, my research will cover typical blocks in six cities, which are categorized based on its height from low to high. Beijing and Kyoto have long history of urban development and the mix-use of low-rise traditional blocks is formed organically during a long time. For Madrid and Taipei’s modern residential blocks, they are planned as residence zones but they still keep the ground floor as public use with multiple functions for convenience to live there. Blocks picked up for Hong Kong and New York are from the densest urban areas. They are both super high-rise with complex 3D massing strategies with different functions in a single building. These trans-cultural choices as mix-used urban samples for research have different forms and historical developments, but they share the same experience when we walk in these different areas in terms of sense of scale and urban diversity. The reasons behind the similar phenomena of mix-using and different methods of massing organization are worth of research and helpful for our future architecture and urban design. 4

If we look back into the history, large area of the old Beijing used to be a coherent grid composed by blocks of courtyard residences. Because the essential quality of the traditional living residence is the substantial solar access, most of the typical blocks are long bars consisting of South-facing courtyards placed neck by neck in a straight line. This historic fabric still gives a lot of clues to the current urban form in Beijing as the residual grid - a similar urban phenomenon of remnant grid described by Albert Pope in Ladders, for the intervention of post-war urbanisation in historic cities. This urban heritage of remnant grids from old Beijing indicates that the ‘missing’ of a consistent grid of urban blocks doesn’t mean blocks don’t exist in contemporary Beijing. Paradoxically, Beijing has lot of variations of blocks evolved from the historic common ground. They are just too different from each other and extremely fragmented. 6

For most residential blocks planned in modern era, there are many other functions embedded in the same block except for residence.

Small commercial spaces and necessary religious places can meet people’s basic demand for living. Different with two-dimensional organization for low-rise blocks, there larger residential blocks using the simple massing strategy in vertical dimension with public functions on the ground floor and residential part on the top. It is three-dimensional bottom-up relationship.

One of the reasons for Beijing and Kyoto to have mix-used blocks in traditional context is the large modernism building which replaced the original houses. That means the old residential units have been combined together as a larger parcel to be developed as a commercial or business office building. To compare the function ratios of Beijing block and Kyoto block together, we can see that they are similar to share the same FAR about 1.5 and the main function of the blocks is residential. The main strategy for mix-using is focused on how to embed other commercial functions in small-scaled residential spaces. Most of them are placed in front of the original house and organized along the street around the block.

For all the six urban blocks analyzed before, people can walk in these areas with rich urban experiences with different functions.
For the block of Carnegie Center in Manhattan, every single tower building has the uniform facade and exterior looking, but the interior space is developed with multiple functions and flexible divisions.
New York
To maximize the use of a single building getting the largest commercial interest, the blocks in central areas of super-dense cities like New York and Hong Kong are more functionally diverse in 3D space.

New York Statistics 12
No matter how large and how high the block is, they share the similar scale and diversity for ground space which is close to the pedestrian system on the street. The average spatial division for these shops, restaurants and entrance spaces are small and humane in the width about 6-10 meters.
Hong Kong Statistics 13
Typical Block in Downtown Chicago 14
Comparing urban grids in other developed cities, people usually find clear rectangular blocks in similar scales. A simple and algorithm rule on the block dimensions can profoundly affect the way of shaping the urban structure and people’s daily experience. The preliminary research of the block samples in New York, Chicago, Hong Kong, Madrid, Copenhagen and Kyoto, shows that a well planned grid system of blocks can both build up a generic structure in human scales, and also contain great freedom for the architectural diversity and complexity. They share a lot of physical similarities. For instance, no matter how tall or how morphologically different the buildings in the blocks are, the proportion of the block boundaries is fixed in a certain range between 1:1 to 1:2, and the division of the spaces directly accessible to pedestrians is based on the same scale. 15
Not only the number matters, but the three-dimensional complexity of internal organization also determines whether the blocks can affect the urban life in a positive way. Through the wide-range of comparative study, this research rethinks how the morphological elements of successful blocks devote to create diverse urban programs efficiently as complex buildings. They are good examples of ‘urban artifact’, ‘archipelagos’, as well as ‘city in the city’, which maintain the design autonomy with well established internal logic, and simultaneously engender good dialogue with specific urban contexts. Seen clearly by comparison, the morphological and spatial similarities of these successful block samples form up a trans-cultural common sense which is missing in the physical reality of Beijing. The dominance of traffic planning imposed upon various types of blocks in contemporary Beijing makes them flat, monochromatic and lack of an efficient three-dimensional complexity. 16

Mini-mallism
Research for mini-malls as typical objecthood in Los Angeles Abroad Studio, 2013-2014 Spring Semester Instructor: Michael Maltzan Solo work This research proposal is focused on one of the most typical urban figures in Los Angeles - mini-malls - which are so ordinary and ubiquitously distributed in the large urbanism ocean. In 1960’s, mini-malls have attracted the interest of some contemporary artists like Catherine Opie, Edward Ruscha who documented them by photography. Nevertheless, a comprehensive research about mini-malls for Los Angeles, which should give us a clear and systematic understanding of these important urban figures not only in the dimensions of urbanism and architectural typology, but also expansively in the cultural and social parlance, is still lacking. The main purpose of this research is trying to establish a systematic framework to speculate deeply into an overlooked urban typology, in the trans-dimensional and trans-disciplinary way as a more specific approach to understand the complex of Los Angeles.

This research proposal is focused on one of the most typical urban figures in Los Angeles - mini-malls - which are so ordinary and ubiquitously distributed in the large urbanism ocean. In 1960’s, mini-malls have attracted the interest of some contemporary artists like Catherine Opie, Edward Ruscha who documented them by photography. Nevertheless, a comprehensive research about mini-malls for Los Angeles, which should give us a clear and systematic understanding of these important urban figures not only in the dimensions of urbanism and architectural typology, but also expansively in the cultural and social parlance, is still lacking. The main purpose of this research is trying to establish a systematic framework to speculate deeply into an overlooked urban typology, in the trans-dimensional and trans-disciplinary way as a more specific approach to understand the complex of Los Angeles. In 2014, I lived in a low-income but convenient neighborhood in Koreatown for a short term and I got so obsessed with shopping and eating in mini-malls. Gradually, I noticed that these mini-malls as non-stop urban figures are actually everywhere at the street corners of any similar neighborhoods. I started trying to get an overall mapping for mini-malls in Los Angeles. Relying on the help of Google map, I picked up a large carpet area from Hollywood to Jefferson to show the locations of all the mini-malls in this area. Inspired by Pier Aureli’s writing in ‘The Possibility of An Absolute Architecture’, the mini-malls are exactly like ‘archipelagos’ in the city which are one of the best generic models to talk about the relationship between architectural objects and urbanism. They have identical features with typological gene while at the same time they can also easily adapt to different neighborhoods with specific design gestures. They are connected with each other as a cognitive map in people’s minds to navigate and enrich people’s urban experience in a flexible way.

The second reason why the concentration on mini-malls makes a lot of sense for Los Angeles is the issue about cars. Minimalls are the harbors for cars where people stop driving and walk again to meet other people face to face. Los Angeles as a car-dominant city, which doesn’t care about urban form at all, yields the most valuable stree corners places for void parking space of the mini-malls. This simple planning decision makes the whole city lose the opportunity to keep a continuous street facade, but create extreme convenience for drivers to move smoothly into mini-malls. In terms of its close implication with driving, mini-mall is a good media to start the discussion about urban resolution based on the basic speculation between scale and speed. When you drive fast in the urban scale of the city, you can only get the ‘identical’ impression of the minimalls with generic features. When you slow down, you get a more resolution with more details and distinctions between different minimalls. After you stop driving and really get in it, every mini-mall becomes special as unique experience. As a typological object, a mini-mall can be either a voiceless urban figure repeated in a blurred and ‘high-speed’ panorama, or a distinctive building with specific design attitudes in a high-res static image. According to this point, mini-malls must be an intriguing threshold for people to initiate a specific but powerful urban speculation in the bottom-up way for Los Angeles. I call it ‘Mini-mallism’.

Boundary The original interest about mini-malls came from my personal experience in Los Angeles in 2014 when I lived in a low-income but convenient neighborhood near Koreatown. The mini-malls play a crucial role in people’s everyday life in the neighborhood. Gradually, I noticed that these mini-malls as non-stop urban figures are actually everywhere at the street corners, and I got so obsessed with these ordinary urban figures which have such a strong power to reproduce itself and adapt to different kinds of communities.
24
Boundary is the most interesting element to talk about the objecthood of mini-malls. As physical boundary, it distinguishes the building of mini-mall from the urban context surface as an isolated and enclosed space. Conceptually, there is also a cognitive boundary between the condition of the mini-mall to be an independent object and its submissive role as one standard component to serve for the whole urban system. The concept of objecthood in the city isolating the figure out of the context is actually closely focused around the topic of boundary. It is a similar concept of ‘Plinth’ from Pier Aureli’s book ‘The Possibility of An Absolute Architecture’. The ‘plinth’ of ‘absolute architecture’ corresponds very well with the characteristics of mini-malls which always have clearly defined boundaries. Both plinth and boundary explicitly describe the urban figures as unique objects with irreplaceable singularity and also generic urban units in the same way. The concept of boundary for mini-malls is a good lens as part of the architectural object. We look through it inside towards the architectural properties of each mini-mall with its special design story or social background. We can also look through it outside towards the whole urban surface, where the mini-malls play the identical role in the same system with gas stations, parking lot or typical LA apartments. From the boundary and objecthood of mini-malls, we can find another perspective to understand the Pier Aureli’s ‘Plinth’ and ‘Absolute Architecture’. 25
26
The objecthood of mini-malls is so special that the morphological singularity and its potential to be generic and identical coexist. The polarity and coexistence of these two features realize the spatial magic which makes it able to be reproduced endlessly in such a huge urban scale. In the description about ‘Flat Ontology’ in Ian Bogost’s book ‘Alien Phenomenology’,which says all the things in the world “equally exist yet … not exist equally”. Minimall is the perfect example to demonstrate this argument in a realistic way. They equally exist in the city as a generic typology, but not exist equally because each of them does have unique morphological adaptation to specific context.
This special objecthood that is similar with ‘Flat Ontology’ can be understood through another concept, urban resolution. It is closely related to the dominance of car-driving experience in the city. Los Angeles doesn’t care about urban form at all and yields the most valuable street corners for void parking space of the mini-malls. This simple planning decision makes the whole city lose the opportunity to keep a continuous street facade, but create extreme convenience for drives to move smoothly into mini-malls. For most of the time when you drive fast in the city, you can only get the ‘identical’ impression of the mini-malls as resistant urban typology with generic features. That is a very low urban resolution because of the collective effect of speed, scale and visual sense. When you slow down, you get more details and more distinctions. Eventually after you stop driving and really get into it, every mini-mall becomes special as unique place. As a typological object, a mini-mall can be either a voiceless urban figure self-repeated in a blurred and ‘high-speed’ panorama, or a distinctive building with specific design attitudes in a high-res static image. Different urban resolutions got from the driving experience provide us with a phenomenological background to think about the coexistence of uniqueness and identicality in the special objecthood of mini-malls.

Another specific reason why the mini-malls in Los Angeles can be so morphologically flexible is due to the whole city’s ethnic diversity. Different ethnic communities would develop or transform the mini-malls with their own cultural influence. If we consider the decorations and billboards as another layer of the morphology or shape of mini-malls, the difference between a mini-mall in Koreatown and the one in little Armenia is even more huge and obvious. The gap of economical conditions of different communities can be also reflected from the design of mini-malls. Most of the newly designed mini-malls are located in Hollywood or West Hollywood, but the ones on the west side of downtown Los Angeles are usually old and lack of good maintenance. According to the visual or literal information read from the form and billboards of different mini-malls, people can easily get enough feedback about the neighbourhood where they are. Interwoven by these multiple layers of cultural and social effects, the mini-malls correspond to the rich contextual information with a particular and unreproducible design solution. The uniqueness of the complex condition of each neighbourhood is the resource to endow the minimall objecthood with morphological diversity and flexibility
Boundaryless Beyond the clearly defined boundary of each mini-mall, if we think about them as abstract urban figures again, the power of the mini-malls working together as an urbanistic mechanism is huge and essential for establishing the convenient life of whole Los Angeles. They are in fact ‘boundaryless’. The mini-malls are geographically boundaryless and also psychologically boundaryless, just like the cognitive image of entire LA. The mapping drawing attached below shows how these generic models repeat in the boundaryless way. The whole mapping area includes a large carpet area from Hollywood to Jefferson indicating all the locations of the mini-malls in this area. They have identical features to each other like generic symbols pinned on the map. They are like ‘archipelagos’ in the endless ocean of urbanism described by Pier Aureli. These unstoppable urban objects are linked together as a cognitive network in people’s minds to navigate and enrich people’s urban experience. Sometimes people don’t need to rely too much on the map of iPhone and they just need to read the visual information from the mini-malls to understand where they are.

Existing Mini-mall Prototypes
Mini-malls as Social Places
Mini-malls save the valuable walking experience and enrich people’s urban life by all senses, even on the spiritual level. If we compare the mini-malls in Los Angeles and the temples or shrines in Kyoto where the urbanistic smallness is historic and successful, quite a lot of similarities can be found between these two urban typologies with extremely different programs. In terms of the number in the city and the social role in the neighborhood, mini-malls are like the urban shrines in Los Angeles but just secularized by American commercial activities. In fact, there are some mini-malls parts of which are transformed into community Iglesias especially popular for the Latin American residents. Furthermore, you can also find schools or kindergartens redeveloped from an old mini-mall structure. This flexibility and adaptability into other programs beyond the limit of commercial use shows another way to look at mini-malls’ boundarylessness.
Commercial Space
Parking Lots
In the summer of 2014, a couple of comedians rent a shop at a typical mini-mall in Los Feliz and opened their own coffee shop named ‘Dumb Starbucks’, providing free coffee for people in the exactly same style of the giant chain coffee shop of Starbucks. Minutes after its open, ‘Dumb Starbucks’ got viral online very quickly and hundreds of people lined up in the mini-mall area waiting for free coffee with a lot of fun. It was a great parody show and actually one episode of the docu-reality comedy series ‘Nathan for You’. For this event, the mini-mall became a gallery-like place for performance art. The spatial flexibility and friendliness of mini-malls makes it happen as a successful social experiment attracting people to reflect our common daily life deeply influenced by big chain shop names and typical urban banalities and dumbness. That is quite an understandable reason that Starbucks didn’t pursue any legal actions on them. 30

New Parking System
The design of the new mini-mall is based on the morphological analysis of the existing mini-mall typology which is normally composed by a L-shape single story or double story building and a parking lot. The new form of the mini-mall will consist of two L-shaped volumes, one of which is the regular office spaces and the other one is distorted and disformed to create a more dynamic commercial interface. The transformation of the parking system is also a key design element in the new minimall design. The orginal parking lot will be developed as a double-stroy 3D parking structure which uses the ground space and the roof space in the middle in a very efficient way. 34

The third main design intents is to create an inner alley on the back side of the new mini-mall. This is aimed at to recover what is missing in the urban experience in Los Angeles. The formless of the whole city and the absolute dominance of car-drivings makes it lack of continuous street interface and interesting street life. For most buildings in Los Angeles, they have a clear front side facing to the parking lot and a back side which is totally negative with nothing to explore. Between buildings there are usually just busy car traffic or another parking lot. This makes sense for Los Angeles to keep the smooth movement by car as the absolute priority for the entire urban design. However, it is still an intriguing urban experiment to re-generate an introverted, pedestrian and narrow alley spaces to bring back the traditional street life with an intimate scale. The mini-malls provide great opportunities to be inserted with the newly-created alleys.

The re-generated alley space is inserted at the north side of the mini-mall where is usaully designed as a partition wall with the adjacent parcel. The new mini-mall design yields a narrow and curve linear space from which people get access to a series of small-scaled shops, restaurants or other recreational spaces. This intimate alley space would attract more people to walk through the back side and make the original dead wall alive with vivid street life. Working together with the front plaza and the pedestrian system around it, the back alley is part of a pedestrian circulation loop passing through the whole structure and integrating all the activities tightly in a continuous way. From the newly created alley space, people in Los Angeles can enjoy the colorful small urbanity with diverse and intimate experience again. The hidden and introverted atmosphere around it renders this small linear space even more tempting for people who pause the driving and want to explore another version of Los Angeles life by all senses of the body. 38

Subdivision/Disassembly
Micro-living System Design for Kyoto Studio work, 2012-2013 Fall Semester Instructor: Toshiko Mori Solo work In the perspective of urbanism and architecture, the concept of disassembling is different from the counterpart for sculpture, furniture or industrial products of which the disassembled parts are more unique and distinctive. The city or a building is dominantly controlled by the continuous spatial logic as a whole and the disassembled components would share more identical rational or form in a repetitive way. In this case, before the discussion about disassembling, another important concept – subdivision – is unavoidable. It is crucial to get the way about how to disassemble a city or building both physically and logically.
42
43
Kyoto is a good example to discuss about the city of subdivision and disassembling. It is a city with a simple logic to subdivide a rectangular land into more smaller gridded blocks. Furthermore, one block (Cho in Japanese) continues to be divided with a regular grid order into different parcels with different size and scale. These subdivided Chos share the simple and similar planning order with identical rectangular boundaries while at the same time contain diverse and different architectural elements which create distinctive personalities for different Chos. According to this logic of subdivision, the whole city can be disassembled to a huge set of colorful portraits of Chos. Within the boundary of each Cho, this subdivision-disassembling process can be continued in a further step to parcelize each block and even apply it into the design of a typical residential building.

The co-existence of the urban continuity and diversity is realized through the historical accumulation. The modern Kyoto is developed based on the ancient urban planning of Heian-kyo which is borrowed from the paradigm of Changan in China The simple and infinity grids system has been changed and subdivided into smaller scales as the population and density of Kyoto increases. Then through the process of modernization, many small scaled buildings have been replaced by large modern constructions which form the urban diversity together with the existing traditional structures.
Kiyacho 茶屋町
47
This urban subdivision can be continued applying for the design of a typical residential building in one parcel. Considering about the high density of Kyoto City and the large demand of young people for more affordable houses, I intend to design a micro-living system with small living rooms. That will be a dense and compact project. The design thinking comes from the section to subdivide a traditional house further into more smaller and similar micro houses and rooms.
Inward Subdivision 48
The final project is composed of 13 small houses with 44 single rooms. There are two types of houses and both types have the shared function space with restroom, kitchen and laudry. One smal house can be used by a family or shared with 3 or 4 young single people who spend most of the time in urban public spaces. 49
50
Disassembling
The new micro-living system designed according to the similar logic of urban subdivision can be disassembled totally to show the individuality of each living unit. The disconnection between different units in this drawing conjures the hidden relationship between them as the integrity. At the same time, each unit with unique personality of the tenant makes itself as an independent small world with potential possibility to generate infinite diversity in the social dimension.
51
Urban Facilities to the Building
The inner space of one micro house continues the spatial logic of subdivision. Using natural materials such wood, paper and mud, the interior design follows the modules of traditional scale of Tatami and Kyoto wall. The inside space is built totally with natural materials while the outer skin is built with concrete wall and steel columns to support the whole building and provide it with infrastructure. The size and portion of Kyoto wall and Tatami control the design of the single room and the organization as a micro house. It is a crowded and dense space with a warm and comfortable environment.

Interior Materiality 52
ntegrating the two thinking processes about subdivision and disassembling provides people with a new method to read the classical relationship between city and architecture. Also, it is helpful to understand the compositional logic in architectural approaches between the basic elements and the integrative whole. The subdivision thinking is more alike top-down process to assist people read clearly of the cells and capillary system of the whole body, while in the meantime the disassembling thinking starts from the singularity of each cell with independent characteristics and transforms the body to a disconnected but more diverse one with absolutely fresh inspiration. To keep a balance between the thinking of subdivision and disassembling can not only make sure of a continuous design control, but also enrich the potential possibilities to generate diverse and distinctive small stories based on disassembled individualities.

Shanghai BaoSteel Industrial Park
Urban Design Proposal for BaoSteel Industrial Park Baoshan Districk, Shanghai Collaborators: Yaohua Wang, Dingliang Yang, Shouquan Sun 2016 This urban design proposal is tying to meet the new ambition of the local government of Baoshan District in Shanghai, that transforms the desserted industrial site for steel production, to a new urban complex with multiple programs. As one of the most significant steel producers in China, BaoSteel’s old site is huge and holds a series of amazing industrial structures worth of preservation and redevelopment. In this design, we propose to transform the preserved structures into cultural centers around which the new neighborhoods for living and working will be created. It will be a new integrative and self-sufficient micro city in the suburban area of Shanghai, as an urban design paradigm for humane-scaled blocks and diverse architectures within a clear planning order.

Baoshan District is located at the north part of Shanghai, composed of mainland part and a couple of islands next to it. It is at the intersection where the Huangpu River converges into Yangtze River. Baoshan is the district which works as the gate of waterway transportation for Shanghai, where many important ports are located inside. That is the reason the BaoSteel chose here as the main production site and became one of the most significant steel production companies in China. After BaoSteel moved farther away from downtown Shanghai, the existing site in Baoshan has been desserted for years. It is a huge site with a couple of amazing industrial structures. Our main goal of this design is to bring a new life to these desserted buildings as cultural centers which will further vitalize the whole site for a multi-program use of urban complex as the new center for Baoshan District.

The North-South and East-West eco corridors are the main structures for the whole urban design. Grown from this spine, the road net work expands into the neighborhoods creating series of human-friendly blocks. The basic zoning divide the whole site into several parts for the main programs of residence, office and commerce, while within each zoning district, the different programs are also mixed to a certain extent in both 2D and 3D methods. The preserved industrial structures are redeveloped as the cultural and exhibition centers scattered at different locations as the main public spaces for the whole site. Around these cultural centers, the smaller scaled buildings for residential and office use are arranged under the design principle to create a central yard surrounded by diverse architectural forms. These humane-scaled courtyards work together with the main eco corridors as the landscape net infilled expansively into the whole site. New Constructions 68
