Design for Uncertainty by Ahmad Ramezanzadeh

Design for Uncertainty: Finding New Strategies to Revive The Industrial Buildings of Goose Island in Chicago Master Dissertation By Ahmad Ramezanzadeh Under the Supervision of Martine De Maeseneer 1 Faculty of Architecture KU Leuven June 2021

Abstract What does ‘design for uncertainty’ mean? Is it possible to design an architecture when uncertainty has skyrocketed, e.g., without knowing about the function and the use of a building? Can we bene t from an extreme state of uncertainty in favor of architectural planning and design? Considering a city and its architecture as an image of the zeitgeist of an era, the most prominent characteristic of our era is perhaps uncertainty. We live in a time of great uncertainty. Climate change with the rampant development in communicational technologies and transportation modes, all with the emergence of COVID-19, has created a transformational condition at an incredible speed that has deeply challenged and changed our lives. How we live, use, and interact with our built environments is changing with an unprecedented frequency and depth. Today the survival of our buildings and urban structures depends on their capacity to adapt well to our changing living and working habits and behaviors. In other words, to realize the idea of functional architecture, one must recognize the uncertainty as the main problem of architecture. Starting an architectural/urban project in an uncertain context requires a new approach towards architecture and urban design based on 'possibilities' rather than 'certainty.' As the result of the ux of possibilities, a living complex requires maximum exibility. A exible living complex accepts various functions and users who have their own spatial needs. In this new vision, where the users can shape and build their own spaces, the result would be a dynamic and diverse living complex, unlike typical today buildings that are mostly based on repeated units and oors.

Introduction The rst chapter of this re ection paper deals with the relationship of uncertainty with architecture. The main goal of this chapter is to clarify that how uncertainty leads to the elevation of architecture. The Second chapter contains investigation about the reasons behind the decline of Chicago industrial sites. In chapter three, the arguments revolve around creating architectural values and exibility as two fundamental strategies of design for uncertainty. Chapter four is a case study from the traditional architecture of Iran as a representative example of a exible and valuable architecture. The aim is to discover how a conventional living complex built almost two centuries ago has remained intact while its sole purpose was to provide housing for a family. Without any demolition, in time, this example and many other similar buildings have transformed into Hotels, Of ces, Museums, Cultural Centres, etc. This Incredible Flexibility is possible thanks to spatial diversity, which is missing in most of the buildings in Chicago. Chapter ve is the results of the proposed solutions and strategies applied to an existing building in Chicago. Since the proposals apply to any living complex, I chose a regular of ce building with a typical plan and layout, similar to most buildings in the industrial landscape of Goose Island in Chicago.

Background/ Problem Statement Today, the landscape of Goose Island, the location of our target site, is damaged. A long time ago, it was a vital and active industrial area. With the migration of workers to cheaper cities and policymakers’ tendency to moving industries out of the urban areas, this island has lost its vibrant life (Fig4&6). Today, Goose Island's main characteristics are fragmentation by walls and fences, and the buildings are mostly closed to the public. The cost of buying these lands and buildings is high, and many companies prefer renting spaces rather than buying a whole building. E-Commerce, and interest in online working, especially after the emergence of COVID-19, have changed the meaning of working and of ce. In this unprecedented scenario, the users and functions of an of ce block are not xed and prede ned anymore. Thus, we need to de ne and implement an architectural project that works under high levels of uncertainty. Design Questions .What are the sources of uncertainty to be discovered before an architectural construction? .Can we bene t from a state of uncertainty in architectural design? .Considering a possible role of users in shaping and organizing their spaces, what type of design strategies can we employ for an architectural project in an uncertain context? .How does a new of ce building based on the new design strategies building look, and how does it work?

Objectives .Finding new architectural elements and tools for reviving the existing structures in Goose Island .Implementation of spatial diversity in the volume of of ce blocks without demolition of the structural elements. .Designing new plans based on uncertainty, and user’s role.

1. The Relationship Between Uncertainty and Architecture 1.1 Uncertainty and The Human Nature Uncertainty is at the root of our decision-making every day. We consider a decision certain when we are almost sure about its result or outcome. If humans were certain of everything happening in the future, they would never risk, innovate or experiment. Uncertainty challenges the foundation of everything: Our beliefs, economy, way of living, and thinking. In this manner, uncertainty is a bene cial condition asking a designer to use his knowledge in architectural design instead of his skills or rules. ( Fig1). 1.2 Sources of Uncertainty In The Process of Architectural Construction In an uncertain situation, We can not wholly identify the users and functions of a building, and The user's spatial needs are constantly changing. In an uncertain context, the problems requiring solutions are in a permanent state of ux. At the start of a new architectural project, we deal with high levels of uncertainty dictated by the task, Users, and social context. (Fig1,2). 1.3 The Need For a Flexible Framework In the current way of architectural design, an architectural project begins with nding the right solutions—solutions for known users and their particular spatial needs. Usually, At the start of each project, We have relationships with users and bene ciaries, giving them consultations, but then architectural construction ends at a speci c time. On the other hand, In an uncertain context, since the spatial needs of users are constantly changing in time, the construction of architecture is never nished, which means that it requires constant revisions by users and architects. In this scenario, the architecture must act as a highly exible framework shaping simultaneously both by users and architects. . (Fig2,13,14).

1.4 The Importance of Design For Uncertainty Every year millions of buildings become demolished as the result of decay and abandonment. Most of the time, the process of decay is linked to incompatibilities and tensions rising in the buildings. Designing buildings based on certainty leads to xed and static architecture unable to change in time, which means that these buildings can not adapt to new users and functions. This way of design helps the linear economy favoring a shorter building lifespan. With the shift towards the circular economy models and attention to environmental issues, many have realized the importance of increasing the lifespan of existing structures through renovation (Fig3). The process of renovation and the strategies used in this process is critical. We can not renew and copy the existing condition of a building and call it a renovation. Renovation is a thoughtful process requiring revisions and reconstructions to make architecture cope with new realities. The goal of each renovation process is to make the existing architectural structures more exible. In this process, both the users and architects play essential roles.(Fig2). 1.5 The Signi cance of the User’s Role in Design For Uncertainty

In architecture, tensions rise due to the incompatibility of the spaces with the new spatial needs of the users (Fig3). The only possible way for architects to deal with uncertainty in architecture is to give users the power to de ne and control the functions of spaces themselves. We need new sets of strategies and tools to empower the user’s role in architecture. Design for uncertainty requires the architect to avoid two things: undermining the user’s role in architecture and predicting the user’s behaviours ( Fig19).

2. Decline of The Chicago Industrial Sites and The Emergence of A New Working Culture

2.1 Chicago School : Building as an instrument of investment The economic growth of the early twentieth century in America, combined with The speed and easiness of using prefabricated steel beams in architectural construction, Has created a kind of style emerging rst in Chicago, and for more than a century spreading in many places around the globe (Fig4,7). But the instructions for designing the buildings of Chicago School would often come from business people rather than architects or ordinary people, and The architecture of the Chicago school was nothing more than a realization of business requirements. Most of the time, architects would accept the conditions imposed by the Speculators. They had limited themselves to producing buildings that should be no more than the logical instruments of investment (Colin Rowe). Because of the result elimination of both architects and people from the process of architectural construction, The architecture of Chicago school gradually declined in time. Today almost a century after the genesis of the Chicago school, the social context of Chicago is fragile, and the population decreases each year (Fig5,6). Many buildings have become abandoned, and many are decaying and waiting to be demolished or saved by business moguls. 2.2 The Monotone And Repetitive Architecture of Chicago The uncertainty is a state dictated to architecture by people and the social context (Fig1). Design for uncertainty is effective only if we put these two essential sources of uncertainty at the heart of our solutions. The monotonous look of the Chicago buildings results from the elimination of users as the primary sources of uncertainty from the process of architectural construction (Fig8). It is not the repetition of the frames making these buildings monotonous (Fig7). Monotony results from applying strict economic rules crippling the architecture from adaptation to various functions and users (Fig8,9,10). Expecting humans to live in a condition preconceived by architects and Speculators is against the aim of design for uncertainty. We cannot oversimplify and anticipate human desires and actions by giving them a cage rather than space. Man considers a place personal when he imposes his desires and reality on it. If he nds the architecture surrounding him is limiting and damaging him, he leaves it.

Before the emergence of COVID-19, the role and effect of internet-based communications were inconspicuous in our lives. Covid-19 provided us with an unprecedented opportunity to improve the ef ciency of online working. A few months before writing this paper, Twitter’s CEO announced employees would be allowed to work from home forever. Today we are sure that even after the end of Covid-19, many jobs will move to homes and remain there forever. As a result of such a phenomenon, a new working culture is emerging. Today an of ce is not fully occupied, But instead rented for a particular reason at a speci c time. This new reality requires a different approach to designing an of ce building—a new architecture based on uncertainty coming from unknown usages and users. 2.4 The Dilemma of ‘’Form Follows Function’’ And The Importance of Rede ning The Meaning of The Function of Space The famous sentence from Luis Sullivan,‘’ form follows function,’’ was a rational answer to the industrial and economic situation of the early 20 century. The function of the of ce was clear, and there was no place for any other interpretations. Today a new working culture has emerged. Today an of ce is not fully occupied, But instead rented for a particular reason at a speci c time. This new reality requires a different approach towards designing of ce buildings—a new architecture based on uncertainty coming from unknown usages and users. The ‘’Form Follows Function’’ is one of the fundamental pillars of Modern architecture. But since the function of architecture is constantly changing, rethinking the function of architecture is crucial. In a time of great uncertainty, our buildings cannot have a single function anymore (Fig11). Architecture is always in a state of ux; A xed and static form as an architectural entity can not survive in an uncertain context.

3. The Need For a Flexible Framework 3.1 Maximising Flexibility and Creation of Architectural Values/Qualities as Two Complementary Strategies to Design for Uncertainty In an uncertain context, the architecture must act as a highly exible framework—the Strategies related to maximizing exibility help the architecture to respond to more possibilities. And the strategies regarding the creation of architectural values/qualities strengthen the architecture against decay (Fig12). Since one of the exibility’s aims is to import the element of time in architecture (Fig13), we have to be sure that an architectural structure could stand in time. Implementation of solutions regarding exibility in a weak architectural structure will not provide a desirable effect. An architectural structure must have enough qualities such as rmness, enough light, Good Ventilation, Good Insulations, easy accessibility, readability, etc. These qualities are the preconditions of reaching exibility in architecture.

3.2 The Signi cance of Flexibility in Architecture ‘’Flexibility signi es - since there is no single solution that is preferable to all others - the absolute denial of a xed, clearcut standpoint. The exible plan starts out from the certainty that the correct solution does not exist, because the problem requiring solution is in a permanent state of ux, i.e. it is always temporary.” Hertzberger 3.3 Flexibility: an Inherent Ability In Human Beings Human beings are exible creatures. We move about at will, manipulate objects, and manage to operate in a wide range of environments. There was a time, not too long ago in evolutionary terms, when our existence was based on our capacity for movement and adaptability - indeed; it is to this that we owe our survival as a species. After a few thousand years of more or less sedentary life, it could be that exibility is once more becoming a priority in human development and that technological, social and economic changes are forcing, or at least encouraging, a new form of nomadic existence based on global markets, the world wide web, and cheap, fast, transportation.(Robert Kronenburg). 3.4 The Modern Interpretations of Flexibility The strategies regarding exibility are traceable in Modern architecture, and they are mostly related to open plans. The open plan seemed a good system for small living units. The ability to combine spaces with sliding doors and using minimum walls were tools in the hands of the architects to minimize the size of space and material used in the process of architectural construction. Another attempt of modern architecture was to make architecture pure. ‘’The aspiration in modern architecture is to aspire to a lightness of geometry and minimalism where more and more ‘non-essential’ features are taken away in order to achieve a state of purity. although this creates undeniable beauty, it also meant that people would also be taken away’’ (Fig15). (Robert Kronenburg)

Fig15- S. R. Crown Hall, Ludwig Mies van der Rohe, Chicago, 1950 .The aspiration in modern architecture is to aspire to a lightness of geometry and minimalism where more and more ‘non-essential’ features are taken away in order to achieve a state of purity. although this creates undeniable beauty, it also meant that people would also be taken away (Robert Kronenburg)

Another approaches towards exibility is traceable in the examples from the contemporary architecture of Japan. Toyo Itto has developed a design strategy that had now taken precedence in his works– searching for a uid architecture that only becomes complete once people inhabit and use the building (Robert Kronenburg). He meticulously designs the plan based on the conditions of the site and necessary functions. Then he places a big portion of functionless volume inside his architecture so that the people will nd out how to use it themselves (Fig16). We can trace the same approach in the work of SANAA and Isigami, who were admirers of Itto. Ishigame’s approach towards creating a chaotic and unpredictable plan helps people nd their desired spots inside this architecture (Fig17). This chaotic plan is readable thanks to its lightness and transparency .(Robert Kronenburg).

Fig18-Kanagawa Institute of Technology, Japan. Flexibility as a result of an unpredictable and chaotic plan. The plan is readable thanks to its lightness and transparency.

3.6 Separation of Served From Servant Spaces The separation of served from servant spaces is an action coming from human nature. We always separate dirty areas from clean, workspaces from sleep, guest spaces from private, etc. But The problem arises when we don’t have enough space and want to have a special place for these dichotomies. The ideal condition would be that we design separate rooms for them, but in reality, we don’t have that much space in a living complex. Since the human behavior inside served areas is unpredictable(Fig19), the separation of the servant spaces from served spaces aims to free The heart of a plan to make room for more exibility and more spatial possibilities. 3.7 High-tech Architecture At the core of many high-tech buildings is the concept of the "omniplatz". This is the idea that a building and the spaces within it should not necessarily be absolutely de ned, but rather perform a range of desired functions. As such, a room in a high-tech building could be used as a factory oor, a storage room, or a nancial trading center all with minimal re-distribution of structural elements. The external services of a high-tech building, in this understanding of the style, exist solely to make the central space habitable and do not de ne its function (Fig21). This can lead to an effect wherein the maintenance elements of a building can be understood and interpreted without issue, but the function of the interior space is dif cult to guess.

4. Case Study: The Golshan House In Yazd 4.1 Introduction This chapter aims to discover how a conventional living complex built almost two centuries ago has remained intact while its sole purpose was to provide housing for a family. Without any demolition, in time, this example and many other similar buildings have transformed into Hotels, Of ces, Museums, Cultural Centres, etc. This Incredible Flexibility is possible thanks to spatial diversity, which is missing in most of the buildings in Chicago. Spatial diversity strengthens the connection with natural elements leading to a healthy life inside a living complex. It is not the presence of decorative arts that makes the Golshan House valuable. The greatness of this house is because of its complex order of spatial arrangement and the hierarchical orders between different spaces. Persian traditional architecture employs various elements and tactics to deal with the harsh climatological situation of Iran. Thickened Walls, Wind catchers, Sunken Courtyards, Mashrabiya (A wall or window That allows light to Enter but blocks Visibility ), Ivans ( Have Similarities to Terrace ) are all signs of awareness about the effects of climate on buildings and users. Without these elements, Man would suffer from a harsh environment and could not enjoy living.

4.2 The Concept of Garden In the most living complex of traditional Persian architecture, the center is a garden, a unique and practical spatial quality in the dry and hot climate of the central plateau of Iran. The Garden is the dearest space in a culture that encourages people to improve the earth by making gardens (Fig32,25). One can not step into this honored space Without hierarchy; Without passing through a series of in-between spaces and mediators that blocks direct entry (Fig33).

4.3 Spatial Diversity And the Dualism of Filled And Empty The strategy of spatial diversity is executed in a complex by embedding different size multifunctional rooms with different volumes (Fig25,31). Each space has a function related to activities during a speci c season, and the plan is not fully used during a season. Since there were no mechanical air conditioning systems, the users would move to different parts of a living complex to live in a more suitable place in a speci c season. This process of micro migration inside a living complex creates a dualism. A dualism of lled and empty and a traditional house doesn't consider empty spaces futile. They are necessary for the complete process of living inside architecture during a year. 4.4 Balance Between Positive and Negative Space By creating negative space, spatial diversity's strategy makes a balance in architecture— a balance between negative and positive spaces (Fig25). When we look at most modern buildings in Chicago, we see positive spaces with minimum voids. The positive space lls the entire Building (Fig8). The architecture of most of Chicago's buildings is out of balance. There is no place to breathe and no place to connect with natural elements such as air and sunlight.

4.5 Functionless Spaces Room ( Space / Chamber ) in Iranian traditional living complexes doesn't have a prede ned function such as dining, living, or bed. Room is a spatial quality that is ready to host any activity. Inside a Room, You Eat, Read, Gather, Sleep, Work, etc. This uidity of functions re ects in the name of these rooms. They are named based on the number of doors attached to them (Fig31). The doors are the unique part of these rooms. They function as separators and connectors between different spaces inside a complex (Fig 35,36,37). 4.6 The Four Ivan Plan The Four-Ivan is one of the most ancient architectural plans existing at the heart of the Golshan House (Fig30). There are many reasons behind this particular spatial organization, mostly relating to the culture and climate of the central plateau of Iran. This Architectural organization was developed in Iran for more than two millennia until the early 20 century when the Persian culture and society became unstable under the in uence of western cultures. The Four Ivans (Terraces) cover a garden or a courtyard inside a building complex. Ivan is a semi-open space offering a buffer zone between the rooms and the garden.

4.7 The Importance of Hierarchical Orders The hierarchy in architecture has always been an essential element. The sequence of reaching the innermost in architecture, which is a transition from public to private, bright to dark, from open to closed, is a necessity for a balanced architecture. Each step in a hierarchical order has a deep meaning, and the spaces related to them have speci c functions (Fig33). Hierarchy puts a mediator between two extreme concepts: Open space and close space. This mediation emerges in many forms, as a semi-open space or an in-between space. This hierarchy creates diversity both in plan and section, which leads to the completion of architecture. In the traditional architecture of Iran, a living complex without proper hierarchy is unstable and unsuitable for human settlement.

But it is Mostly deeply related to the culture and climate of the central plateau of Iran. This Architectural organisation was developed in Iran for more than two millennia until the early 20 century when the Persian culture and society became unstable under the in uence of western cultures. Normally The Four-Ivans (Terraces) covers a garden or a courtyard inside a building complex. Ivan is a semi-open space offering a buffer zone between the rooms and the garden.

Fig38-The Aghazadeh Complex In Abarkooh . a conventional living complex built almost two centuries ago has remained intact while its sole purpose was to provide housing for a family. Without any demolition, in time, this example and many other similar buildings have transformed into Hotels, Of ces, Museums, Cultural Centres, etc. This Incredible Flexibility is possible thanks to spatial diversity, which is missing in most of the buildings in Chicago. Spatial diversity strengthens the connection with natural elements leading to a healthy life inside a living complex. It is not the presence of decorative arts that makes the Golshan House valuable. The greatness of this house is because of its complex order of spatial arrangement and the hierarchical orders between different spaces.

5. Renovation Of An Existing O ce Block in Goose Island Based On The Principles of Design for Uncertainty Intervention Plan 1. The structure and all the frames remain untouched. The only removed parts are nonstructural horizontal surfaces. (Fig 64) 2. The architect implements spatial diversity by creating negative space inside the building and underground. Done by removing some non-structural horizontal surfaces. ( Fig62,63,64) 3. The architect implements the strategy of the Separation of servant spaces from served spaces. It is Done by relocating servant spaces such as the staircase, elevator tower, and toilets from the center of the plan and attaching them to the facades. The attached units are the only xed parts of the building. ( Fig47,48,50) 4. Breaking the repetitive circulation of access to upper oors. Done by attachment of stairs and elevators in different positions on each oor. This strategy creates a different plan on each oor, creating more diverse spaces (Fig 48,56) 5. Adding a dynamic facade system for better control and better climate response. ( Fig 43,44) 6. Implementation of new Separator/Connector elements with small bulk on plan. Sliding Glass panels, Rotating Glass Panels, Accordion Separators, Rotating Shading Panels, Sliding wooden panels all changing by user’s Will. (Fig 45,46)

6. Conclusions The uncertainty is a state dictated to architecture by the people and the social context. Design for uncertainty is effective, only if we put these to important sources of uncertainty at the heart our solutions. The monotonous look of the Chicago buildings is the result of the elimination of users as the main sources of uncertainty from the process of architectural construction. It is not the repetition of the frames making these buildings monotonous. Monotony results from applying strict economic rules crippling the architecture from adaptation to various functions and users. Expecting human to live in a condition preconceived by the rules of economics is against the the aspirations of design for uncertainty. We cannot oversimplify human desires and actions by giving them a x cage rather than a space. Man consider a place personal, when he impose his own desires and reality to it. If he nds the architecture surrounding him is limiting and damaging him, he leaves it. In the new renovation plan for the industrial of ce blocks in Goose Island, each oor is different and changes according to the user’s will. Each oor is like an image of the real ground with its diversity and unpredictability. The result is a more exible, responsive, and adaptive of ce block for the new working culture rising form the new uncertain context.

What does ‘design for uncertainty’ mean? Is it possible to design an architecture when uncertainty has skyrocketed, e.g., without knowing about the function and the use of a building? Can we bene t from an extreme state of uncertainty in favor of architectural planning and design? We live in a time of Great Uncertainty. Climate change with the rapid development in communication technologies and new transportation methods, all with the emergence of COVID-19, has created a transformational condition at an incredible speed that has deeply challenged and changed our lives. The way we live and how we use and interact with our built environments are changing with an unprecedented frequency and depth. Living in an uncertain situation may sound unpleasant and desperate. Still, one could bene t from it if he/she sees it as an opportunity to break from routines and old rules to develop new ideas and solutions coping with emerging realities. Starting an architectural project in an uncertain context requires a new approach towards architecture based on ‘possibilities’ instead of ‘certainty’. As the result of the ux of possibilities, a living complex requires maximum exibility. A exible living complex accepts various functions and users who have their own spatial needs. If the users could shape their own spaces, the result would be a dynamic and diverse living complex, unlike typical Chicago buildings based on repeated units and oors.
