Housing Problems for Displaced People Today, we are witnessing a rapid increase in population and, as an result, an ever rising demand for dwellings. However, the construction and subsequent supply of such dwellings does not match the rate at which the global population is growing; double in number! T here are thus speculations that we will need to build 2 billion new homes over the next 80 years to satisfy the global need for shelters (Smith, World Economic Forum). T his shortage of dwellings is problematic, especially for people who f ind themselves hav-

survive in extremely poor living conditions. In 2018, there were an estimated 13.6 million people that were newly displaced due to conf lict or persecution. Among those people, the largest f lux was observed into Turkey, with an immigration number of 3.66 million people from Syria alone as of September of 2019. For this reason, we decided to focus on Turkey, and more specif ically Istanbul, where most of the displaced people are concentrated. By targeting a large moving community, we believe we will be able to provide enough

ing to leave their homes for reasons linked to war, political instability, economic crises, and natural disasters. Displaced people thus end up with no shelter, having to f ind ways to

shelters for many of those people that are currently struggling to settle in Istanbul, or that will be arriving to the city in the future.

Istanbul Urban History Istanbul as a transcontinental city is the world’s f ifth largest city in terms of population, and expands over 110 km along the Marmara Sea. T he city centre is heavily populated with a density of 2, 523 people per

square kilometre. Over the past one hundred years, Istanbul has rapidly increased in terms of population, growing by more than 1 million people in 2015 and reaching 15,190,336 people to day.

Istanbul Urban Data Observing the growing population in Istanbul and the current housing shortage, we aim to develop a housing system that minimises private living space to accommodate people in a relatively small personal space. Simultaneously, it is our goal to create a minimal stand-

ard of living including a water and electricity network. Deriving from the chart below, we will also have to consider the fact that 45% of daily trips of people living in Istanbul are carried out by walking or cycling.

door spaces for families and children and a variation of commercial areas and pop up stores for young professionals who are set to start their small businesses after settling in NeceCity.

Issues and Responses T he aim of the project is to plan and spatially organise the growing number of displaced people living in cities, as most of their current accommodations are isolated on the outskirts or outside of cities. T he required need of community in such an environment is leading us to consider having more common spaces as well as to improve their living conditions by adding independent energy and water access points to their living units. We propose a solution adapted to the current situation in cities considering local integra-

Our intention is to develop a modular system around a common space. To allow diverse living scenarios over time, we have to build a decentralised system to better react to social changes and heterogenous tenant compositions. T he structure made of durable materials reflects and reacts to socio-demographic changes; therefore, it needs to be able to be quickly assembled and reassembled.

Budget for Temporary vs. Permanent Shelters Although money from humanitarian aid has been used to build new homes for displaced people, we believe it could be invested in an alternative and much more sustainable way in the long run. Organisations are currently using funds to mount temporary shelters such as life kits, emergency tents, and the quick construction of “camps;” when the same amount of money could actually be invested in building dwellings with a much .longer life cycle

“L’unique question, pose Coulombel, est de savoir pourquoi il faudrait se priver d’une construction pérenne, alors que le prix d’une intervention temporaire est aujourd’hui en mesure de la couvrir.” [T he only question, is asking Coulombel, is to know why we should deprive ourselves from a permanent construction, while the price of a temporary one is able to cover it today.] Sibylle V incendon, Architectes de l’Urgence,

T herefore, our main concern would be as such: How can we provide quick-assembly long-term shelters for displaced people, all the while addressing the idea of the formal ( permanent ) and the informal (temporary) aspects of construction?

Basic Necessities Our aim is to create minimal living spaces for displaced people. Every predef ined response is falling into one of the categories covering basic necessities according to the UNHCR.

NeceCity :

T his classif ication helps us to address basic needs for a human being in terms of personal space, water and energy infrastructure in order to provide an adequate use of space. In addition, these responses represent the foundation of our project.

Basic Necessities for Water, Energy & Space For the use of water and energy, we made calculations according to the minimum consumption. T he variables for water use are divided between Hand-wash dishes (4%), Toilet (22%), Bathroom hot tap (7%), Garden (1%), and Other cold taps (41%). T he volume for the water tank is calculated for one person and is gradually adapted for the size of each household.

For the energy consumption of one person, we considered the usage of electricity for a light bulb, the charging of cell phone, laptop, power bank, cooling and heating in a single day. For the use of space, we referred to the numbers from UN Habitat for Turkey and adapted them to our project. T his project encourages us to think how much space one really needs and how much can actually be shared with others.

2.Site Analysis




Location T he site we chose to work on is located in the south of the Fatih district in Istanbul. It is mostly a residential area with small businesses such as cafĂŠs, restaurants and local shops; but also has a port which acts as a main transit hub between other parts of Turkey and the Marmara sea. It is a coastal site which boasts of many historical and cultural monuments without being overcrowded with tourists. In placing our project there, we hope to form a symbiotic relationship between lo-

cal residents and displaced people through exchange of cultural and retail activities. To achieve that, we will create connections between specif ic existing urban spaces of interest and newly created spaces to strengthen the bond between the two communities. In addition, we will distribute various forms of energy produced in NeceCity to inhabitants of surrounding buildings in order to make the neighbourhood more ecologically sustainable.


Site Analysis We plan to inhabit open spaces in the city without intruding on public places, while still maintaining a certain level of porosity in the urban fabric.

Network Choice As a natural choice people wouldn’t use the coastal area,. A reason for that is the bad connectivity between the city centre and the coastal line, as it is fragmented through the highway, which provides no opportunity to cross by walking.

Most probable choice for Pedestrian

T he main roads used by cars are the ones central. None of the streets along the coastal area are of high use. Our aim is therefore, to develop a more attractive coastal line.

Core Location After identifying the open spaces in the urban fabric, we compared them with the location of public benches and cafĂŠ seating places. Our intention is to connect the abandoned lots or leftover spaces with some active places to render pedestrian circulation more smooth and pleasant.

Out of many identif ied open spaces, we selected the ones with the highest visibility extent, according to the Isovist optimisation analysis.

To do that, we created a Steiner Tree expansion model

that spans in the residential area as well as into the sea using points that we hand picked in empt y open spaces (abandoned lots, terrains vagues, informal parking lots, intersti tial spaces, etc .). T hen, we placed the cores at the ends of the bifurcated branches of the tree. Follow ing this logic, each core is supposed to be located at a minimum spanning distance from another, thus strengthening the network relationship of the points chosen.

3.Design Concept




“Plugged-in NeceCity”

048


Design Approach “City, assembly line of social issues, ideology and theory of the metropolis.” No Stop City Andrea Branzi, 1969

Our design concept starts with the simple idea of the plug. In reference to the socket grid, Andrea Branzi claims in his “No Stop City” that people’s behaviour is restricted by electricity; which we can observe today more so than ever. “No Stop City” is based on the idea that advanced technology could eliminate the need for a centralised modern city. T he human dependence on electricity has become global, and has ever since dictated our day-to-day lifestyle. On the bottom left picture is an example of a group of displaced people gathered around a plug-in charging station at an emergency shelter in Turkey.

No Stop City Andrea Branzi, 1969

A 21st-Century Migrant’s Essentials: Food, Shelter, Smartphone New York T imes, 2015 049


Plug as a system To elaborate on this idea of Plugged-in“ness”, we view the city as a network of plugs and extension cords, whereby we activate urban spaces socially, culturally, and energy-wise by providing resources (such as water and electricity). Architecturally speaking, a living unit can be plugged into NeceCity like any electric device connected to a power outlet. W ith this idea of extension cords, we plan on translating our plug-in logic into a structural system that connects different parts of the city.

Composition of Core T he cores, which are considered energy seeds, will be planted in various parts of the site and will be connected to each other through the logic of the Steiner tree ( respecting the shortest path and minimum spanning

tree problems). T hey will thus power the city and ensure equal distribution of water and electricity to NeceCity, as well as to the rest of the existing surrounding buildings.

Bridging as Connectors We used bridges to connect different parts of the local neighbourhood by linking cores in a network system following the Steiner Tree approach. In addition, we placed each core in a way that the radius it covers intersects with the next, hence maximizing the span of resource distribution.

Bridges connecting cores do not only act as pedestrian walkways, but also serve to carry infrastructural elements such as pipes and cables, to distribute to surrounding residential buildings solar energy and purif ied water collected and stored in cores. 052


Composition of Bridge In order to make the walking experience between cores similar to a promenade, we added plant boxes and chose an alternating wooden faรงade to introduce natural light and air circulation.

Pipes Column Tie

053


General Material T he main construction material of NeceCity is prefabricated wood, for a quick, easy, and f lexible assembly process. Wooden structures are assembled on site according to optimised data. T he structure can thus be held together by basic butt joints f ixed with nails.

On the other hand, a semi-lap joint system is used to assemble circular and planar material pieces together. In addition, the sizes of components were designed to allow easy transport by trucks and boats.

Basic Butt Joint

054


T he linear-shaped wooden structures are the most basic components; however, when mounted together at the designated location, these simple components can create a much

larger and more complex infrastructure. T his structure system remains f lexible, allowing the shape of each aggregation to be customised according to people’s needs.

4.Urban Design Strategy




Urban Pattern If cores are the power outlets to the plugin system, how can we then make them the centres of connectivity on an urban scale? In his T he Nature of Order, Christopher Alexander states: “T he wholeness of any portion of the world is the system of larger and small-

er centres, in their connections and overlap”. We translate those centres (or seeds) as activity nodes from which our structure starts to grow in a decentralized manner. T hus, we f irst determine our cores and common spaces, and from them allow living units to generate in a modular way.

“A f ield of centres, then, is a nested series of localities that frame one another and variously connect to one another in a pattern of relationships.”

Generative methods in urban design: a progress assessment Michael W. Mehaffy, 2008

A Pattern Language: Towns, Buildings, Construction Christopher Alexander 1977 060


Connection Theory

Delaunay Triangulation “Delaunay triangulations maximize the minimum angle of all the angles of the triangles in the triangulation; they tend to avoid sliver triangles.� T his method has no hierarchy and too many generated connections between points; making it unsuitable for the purpose of our project. Boris Delaunay, 1934

Travelling Salesman Problem Travelling Salesman is the theory used to seek the shortest possible route that passes through each city and returns to the city of origin. T here is no hierarchy in this method either; and the path connecting the points passes through each one in a one-way linear trajectory.

Steiner Tree T he Steiner tree is used to connect points by lines of minimum total length in such a way that any two points may be interconnected by line segments either directly or via other points and other line segments. T here is clear hierarchy, depending on the number of lines connected with each point. T his method is the only one to link points without going through all other points. We came to the conclusion that the Steiner tree would be the most suitable method out of these three for our project, as well as to connect selected points in the city. 061


Urban Network Experiments

Hierarchical T

T he hierarchy network is a where some nodes on higher connections to the next leve tors to other nodes. In our as all areas, but it performed be ity, and optimisation. T he re topology, however.

Mesh Network We considered the energy-distributing cores already placed on our site as the nodes of our network. T he connections, on the other hand, represent the bridges connecting NeceCity to Istanbul, as well as linking the cores together. T he mesh network is a point-to-point network where all nodes are connected to each other on the same level. In our assessment, it proved to be well-connected, f lexible, and robust; as well as showing high navigability and latency. However, one of the main disadvantages to the mesh network is the redundancy of connections, and therefore subsequent lack of optimisation. In addition, the mesh topology requires a high budget for installation and high maintenance in case of failure of one of the nodes.

062


Tree Network

a tree type of conf iguration r levels in the hierarchy have l and act as central distribussessment, it did not excel in etter in connectivity, scalabilesults were not ideal for this

Steiner Tree Network T he Steiner Tree falls under the category of scale-free networks, and has hubs, or nodes with numerous connections, which new nodes are most likely going to connect to. T his topology represents a hybrid system and is used in real-world scenarios and even natural systems. In our assessment, it performed well in f lexibility, robustness, scalability, and optimisation.

063


Network Topologies Assessment In this table, we compare various network topologies against a set of attributes such as connectivity, f lexibility (or the ability to respond to changes in the environment by adapting), robustness (or the ability to endure changes without adapting), scalability (or the ability to accommodate for future growth), navigability (or the average shortest path between the nodes), latency (or delay in milliseconds to send information between 2 points), optimisation, redundancy (or when information is in sent repeatedly both ways undirected networks), cost, and maintenance.

Urban Grid In order to organise our urban expansion, we f irst started by overlaying regular grids on our site and orienting them following the direction of the pattern of the existing urban fabric and street network. T his example shows a simplif ied version using only 2 overlaid grids.

However, since Istanbul is an ancient city with a very organic urban pattern, we had to f ind an alternative method to eff iciently organise our grid system while still following the city’s urban morphology.

Urban Grid: Aligning the grids with the existing urban fabric

(Right Side) Grid Optimisation: colour coded & adjusted to 15° rotation increments for modularity and standardisation of the model 070


Grid Optimisation T herefore, we used an optimisation tool to retrieve the direction of every block. Starting from the street network, we took points to generate K-means clusters (1) over the whole region. We then analysed the different areas of the city and disregarded some to preserve certain urban qualities such as tourist spots,

archaeological sites ( like the Boukoleon Palace ruins), etc. (2) Finally, we adjusted the rotation of grids (3. + 4.) that we obtained to multiples of 15° in order to render the orientations more controlled and standardised, while still maintaining a certain degree of angular f lexibility.

Section Concept Diagram - Evolution After setting both our cores and activity nodes across the site, we allow the organic yet organized growth of living units around them. Living units will proliferate horizontally in the city and later into the sea after reaching a certain level of density on site. Likewise, they will expand vertically in layers that bridge over the sea and the existing urban infrastructure (such as the highway and railway) for maximum connectivity within the city.

Over the span of several months and even years, NeceCity will grow in size and expand over a larger area of the site as more displaced people move into Istanbul. Here, we predict the evolution of the permanent (yellow) and temporary ( blue) structures that come with the formal and informal( respectively) development of the project over time.

Istanbul, located at latitude of 41° N, receives a yearly average of 10 sunlit hours a day, which makes it convenient to eff iciently install Photovoltaic Panels (1.3 m² per person) on the roofs of our aggregations. Once the solar energy is collected, it is converted to electricity, stored in Power Packs placed on the roofs of cores, and

is ready for distribution. Upon need, electricity is delivered to households via cables running through the bridges infrastructure. In parallel, we propose a water scheme that retrieves water from the sea, purif ies it, stores it in water tanks placed on the roofs, and distributes it in the same manner, via pipes running through the bridges infrastructure.

Core Energy Distribution By placing a mega-structure acting as a connection network for electricity, water, and pedestrian circulation, we are achieving two things in the neighbourhood: 1) we are implementing an energy distribution system that creates a symbiotic relationship between NeceCity ( providing collected electricity and purif ied water) and the existing buildings in the neighbourhood ( providing roof space

for living units and terraces); and 2) by doing so, we are building a sense of trust and inclusiveness between the local inhabitants and the displaced people. In this manner, we would be bridging the intangible cultural gap between the two communities by bridging physical connections between energy-providing cores all over the site.

Hierarchy Organisation In order to organise our spaces, we followed a model of hierarchy linked with our components, living units, clusters, aggregations, and neighbourhoods. T he level of hierarchy moves up, going from most private functions (small scale) to more public ones ( large scale). We specif ically wanted to include spaces that bring communities togeth-

080

er, such as contemplation spaces, micro-agriculture areas; as well as more functional ones such as working spaces. Even though displaced people might not have a choice when it comes to leaving their homes, it was very important for us to make them feel comfortable, accepted, and resourceful in a new environment.


Conceptual Hierarchy In addition, we further studied the organisation of our spaces using coding in Mathematica in order to assign our elements a hierarchical value in each of their respective levels. For our process, we used the concepts

of branching and replacement rules to convert our spaces into a more abstract yet comprehensive computational hierarchy model, whereby we have main spaces branching into smaller elements.

Neighbourhood Aggregation Cluster Living Unit Component


Neighbourhood Level - Urban Scale T he neighbourhood level consists of living units and common spaces for a minimum of 250 people. We calculated the needed size of common spaces, which include functions such as leisure, f itness and work spaces. We not only considered living units, but also of-

084

f ice spaces, as well as commercial spaces. Hybrid programming of living, working and recreational spaces. T he design stands out through the diverse conf iguration of the elements, the functional programming and integration of public spaces.

Neighbourhood - Layout Inside of each grid, we selected cells which coincided with important places in the city, and connected them by using the Steiner tree

086

and closest points method. After selecting these cells, we changed the transparency to f ind overlapped spaces in each.

functions and adaptable design that is customisable by users. Having more than one conf iguration of assembly also adds diversity to shared common spaces in NeceCity.

Neighbourhood Aggregation Cluster Living Unit Component


Aggregation T he level of aggregations is made up of living units and common spaces for 35 to 70 people. Common spaces include a gym, working

096

spaces, and laundrette. T his scale encompasses 7 clusters paired with 1 common space.

Aggregation - Composition In this level, we wanted to divide spaces on the aggregation level. T he f irst diagram shows the voids and solid spaces. T he second and third diagrams show different methodologies of dividing these spaces. T he f irst method we tried uses K-means to cluster groups of points inside polygons and con-

nected by lines. T he second method is from Dr. Sumit’s Decoding spaces. T his method splits polygons into a number of equal areas, while ensuring minimum length of line-based cuts. T he spaces are thus properly divided into several areas.

098


Aggregation - Assembly We also studied different typologies of assembly systems, since the aggregation in itself is an assembly of clusters and other

common spaces. We did not only consider single-level compositions, but we also accounted for multi-storey aggregations.

099


Aggregation - Commmon Space Plan Fluidity Like most spaces in NeceCity, aggregation common spaces are designed to easily adapt to any change of plan or conf iguration following various programs or functions. By

100

adopting a f luid plan approach with f lexible partitioning, the larger space will be divisible by versatile separations yielding multiple layout options appropriate for any activity.


Aggregation - Flexibility T he aggregations, which are combinations of clusters and other common spaces, are designed following a model spanning on mul-

tiples stories, all while keeping f lexibility of various possible arrangements.

Cluster Level T he level of clusters is made up of living units and common spaces for 5 to 10 people. Shared spaces include a kitchen, living

104

room, bathroom, and terrace. T his scale encompasses 2 to 5 living units paired with 1 common space.

Cluster Type A - Composition T hese diagrams show the minimum size of overlapped spaces, which we considered as a shape for our clusters. We got these interesting conf igurations of spaces from over-

laying grids at various angles. Additionally, we considered sharp angles of spaces that could have technical functions, such as pipe shafts.


Cluster Type B - Composition Based on our grid overlays, hierarchy, area requirements for different functions, we were able to automatically generate a combination of several model blocks. T he highest volume represents the common space,

followed by the living unit, and the lowest volume represents the balcony. T his diagram thus shows four different orientations of the three model conf igurations we were able to generate.

107


Cluster - Configuration Flexibility In addition to f lexibility in layout, we also considered different combinations of orientation and sizes of openings for living units in a cluster. W here appropriate for view and

108

desirable sunlight penetration, we included large openings; as opposed to smaller to no openings on sides where direct sunlight might be unwanted.


Cluster - Terrace Flexibility In a similar fashion, we created customisable terraces. T he function is f lexible, ranging from shaded canopy, to closed semi-tunnel with openings on the sides, to a built-in, fully open or partly covered planting pot. T he con-

f igurations depend on the orientation of the cluster, the amount of sunlight it receives, the type of plants in the pot, the privacy desired, and the needed function of the space required by residents.

Living Unit - Installation process After ordering the automated living unit with the desired parameters on the NeceCity app, the living unit makes its way to the allocated cluster using the special dedicated circulation and ramps for automated entities. After

116

reaching the desired location, the originally enclosed cluster automatically opens and allows the living unit to park itself in the assigned space, before closing again.


Living Unit - Mechanical System T he automated living unit drives itself supported by a frame surmounted by 6 small wheels. T he whole mechanism is controlled by a small motor that responds to computational commands initiated by a tiny comput-

erized device including a sensor. T he latter provides a sense of direction and orientation to the living unit, as well as helps maintain a safe distance between moving living units and people.

In order to f ind a balanced ratio between circulation and cluster, we analysed different iterations of building coverage and f loor area ratio. T he aim is to get an optimised and dense yet still porous assembly composition. We then ran a radiation analysis to obtain

the optimal sunlight exposure for solar panels and green spaces. After getting our combined layers of optimisation, we f iltered suitable iterations performance-wise, according to our predef ined rules.

Basic Components for Public Layer

Components for the public layer are wider than components for the dwelling layer.

186


Iterations of aggregation layout for the public layer.

187


Aggregation Experiments

T he aggregation rules for the public layer yield a denser and more extensive composition than the one for the dwelling layer.

188


189


Aggregation Experiments with angle

Similar to the dwelling layer, compositions in the public layer also follow our grid system, and therefore need to adapt to angular situations created by diagonal orientations of grid overlay.

Rectangle Packing Simulation To organise our public layer, we designed the ground f loor following a strategy of rectangle packing simulation. We came up with a series of f lat rectangles and boxes to populate the areas of our public spaces; with

rectangles hosting open outdoor spaces and boxes hosting indoor functions. Each rectangle/box is unique and represents a different program for the public to enjoy.

Types of Component for Rectangle Packing

194


Outdoor-centric distribution

Mixed distribution

Indoor-centric distribution

195


Variations for Each Space Many iterations can be generated for each rectangle and box,. T he smallest rectangle acts as circulation. T he rectangle slightly

196

larger also acts as circulation, only with a sense of directionality. T he largest rectangle represents the functions of plaza, pool, and


green spaces. T he two small boxes contain the arcade, shaded space, and small indoor spaces. F inally, the largest box represents in-

door spaces such as neighbourhood common spaces, market, off ices, etc.

Iterations for Each Space For each architectural manifestation of the public layers, we came up with various scenarios to populate it with different public functions. For instance, a square can be an open space, shaded or not, planted, or serv-

ing for sport activities. Open spaces on the ground f loor and rooftops can equally have a range of public options to choose from, depending on the context and desired cultural and leisure environment.

Isovist Vantage Points We distributed different functions of open spaces according to the level of privacy they require. A pop-up store on the ground f loor will need more visibility than a working space or a contemplation room. According to the visibility analysis provided by the Grasshopper plug-in Isovist, tenants

248

can check on the NeceCityApp their suitable degree of privacy in terms of visibility and their preferred location to live. T his assessment will also allow them to browse around the site and have an insight on the level of visibility in different locations of open spaces.

Wood In response to a rapidly increasing urbanisation and densif ication of urban areas, wood hybrid informal structures can be a conven-

ient, eff icient and environmental-friendly alternative solution for the ongoing global shortage of dwellings.

267


Manufacturing process

Components We tried to make our project as modular, prefabricated, and standardised as possible to make the combinations of different elements easy to achieve. In that same logic, the tenants will be able to customise their own faรงade in a smooth and f lexible process. T hey will have the choice between a few types of timber window frame modules. Additionally, they will be able to choose between two types of doors for the terrace and courtyard: swing and folding doors.

Materials T he faรงade of the majority of the living units, aggregations, and bridges is primarily composed of wood. Wood, being used as a local and vernacular material, is widely available in Turkey. T he main assets it offers in our project are its light weight, ecological sustainability, and f lexibility in assembly. Other materials we are using are carbon f ibre for structure, glass for openings, concrete for footings and cores, and glass f ibre for water tanks.

268


269


Supply Chain In this section, we explain the supply chain for our main choice of material – wood. Raw materials are transported by truck to the component manufacturer, which then cuts the wood into usable “components.” After that, the component are transported to the port by trucks. T he boat loads 10 trucks worth of components, which are then deliv-

* Raw materials from forests 270

ered to the assembled structure manufacturer. After that, the assembled structures are delivered by the same-sized trucks to the supply house, where they are sorted and ordered. Finally, the assembled structures are transported by small trucks to the construction site, ready for hoisting.


Material Life Cycle We also considered the material life cycle for NeceCity. We included more environmentally-friendly and energy-eff icient equipment such as water-saving toilet, more sustainable heating and cooling system, and energy-saving lighting. We also included a rain

collection and purif ication system, in addition to a water tank which stores purif ied water, ready to be consumed by tenants for their daily usage. Hot water re-circulation, solar panels, and gray water recycling systems are also provided in NeceCity.

Supply chain – Process of Cluster Construction After being processed at the raw material manufacturer, the components are transported by trucks as one whole cluster structure. Each truck contains 42 cluster structures.

274

After that, the columns are also transported by a truck containing 200 cluster columns. T hen, according to our NeceCity app control


system, the movable living unit is assembled and automatically delivered to the cluster structure. Finally, additional building “acces-

sories� such as planting pots and benches can be added at this point. T hese elements can be recycled when not in use.
