Preface This booklet is made as a response to the disappearing urban villages in Shenzhen, China. Our project is a motivation of why the urban villages are of value in the modern megacity of Shenzhen. The project was realized in the 2020-21 maig34 studio: â&#x20AC;&#x2DC;Shenzhen: Urban villagesâ&#x20AC;&#x2122;, by Martine De Maeseneer. This research started with a group of KU Leuven international students who went to summer school in Shenzhen from 7 14 September 2019. The master studio adapted the same program last academic year 2019-20. This year our research group consists of 12 students. Later in the research we each found our personal interest and as a result of that our group was divided in two. This project was made by 7 students eager to learn about the mix of cultures, bottom-up urban planning and the life in the villages itself. Our research and project site is located in the upper part of the urban village Baishizhou.

Introduction Made in China China, known for its rapid growth, large population and thriving economy. Since the economic reform in 1976, China has grown at an unseen rapid pace. Currently, they are the world’s most populous country with 1.4 billion inhabitants. They are known for their highly diversified production of goods and are the largest exporter worldwide. We can’t escape the ‘made in China’ products. Without a doubt, China has the fastest growing economy in the world and they are not planning on slowing down anytime soon. With such economic power comes the rise of enormous megacities. Megacities are characterized by the number of inhabitants (+ 10 million people) and the density (+ 2000 people/sqm). These cities thrive to be the most modern and most economic so they can compete with other megacities in the world. China has 8 megacities and Shenzhen, where our urban village is located, is one of them. The emerge of urban villages Due to the rapid growth of the new city and the lack of space, Shenzhen has swallowed up all the pre-existing rural villages which has caused visible tensions. The urban inhabitants, living in the megacity, look down on the rural parts the city has taken over. They see the rural villages as outdated, something that doesn’t fit together with the new vision authorities have put forward. They believe that the rural villages are from the past and they should be demolished. We would like to prove otherwise. These rural villages have transformed together with the city into dynamic urban villages which provide an interesting mix of inhabitants, socio-economic activities and an unique bottom up urban planning. The regeneration of Baishizhou To support our statements for the preservation of urban villages we’ve analysed and introduced projects in Baishizhou. Because Shenzhen is trying to upgrade from a manufacturing industry to a knowledge based industry, there is an influx of different kinds of migrants. The urban village of Baishizhou is known for providing cheap housing, not only for the poor blue collar workers but also for highly educated students and workers. These different inhabitants create a social and cultural mix which brings an interesting element to Shenzhen. Why aren’t these unique urban villages included in the future vision of Shenzhen? Authorities and white collar inhabitants living in the modern city would prefer to ignore these urban villages. Because of this, the living conditions in Baishizhou are really poor. Even though the village is surrounded by gated communities, big skyscrapers, parks and high-tech factories, they have decided to isolate the urban village in hope that they will disappear soon. The issue is way more complex than it seems by this brief introduction. We would like to inform you on the many layers of Baishizhou and the richness that lies in these villages.

Research Reasearch and analysis of Shenzhen and the urban village of Baishizhou. As (future) architects itâ&#x20AC;&#x2122;s important to take a close look into the context to understand the total picture with a sensitivity for history, location, policies and cultures which has created an unique urban landscape.

Shenzhen is the third most populated megacity of China. The city has grown at an unbelievable pace. In onlly 40 years, Shenzhen has transformed from a fishing village to a world dominating high-tech hub. Because of the city’s good location, it forms a part of the Pearl River Delta Megapolis. It’s maritime borders and connection to Hongkong have made Shenzhen the ideal testing ground for the first Special Economic Zone (SEZ). Because of the SEZ (established in 1980) the city could attract a large amount of foreign investments. The city drew people in from all over China and Hongkong, to build and work in the megacity of Shenzhen that we know today.

Special Economic Zone

The Benefits within the SEZ for (foreign) businesses 1. Three to five-year tax exemptions for manufacturing and operating sites by high-tech enterprises. 2. Five-year business tax exemptions for foreign banks. 3. Value-added tax (VAT) and tariff exemptions for imported materials used for finished products 4. Equal living rates for foreigners and local citizens. 6. Immunity from state quotas or permits for production. 7. VAT exemption for goods made and sold locally. SEZ 1. Farmland and villages

2. Industrial development

Shenzhen consisted mainly out of farmland and villages with a small urban center

They are starting to create small industrial developments around the urban core

3. Expansion

4. Current situation

“The migrant city”

Originally, Shenzhen cosisted mainly out of farmland and rural villages. When they started to (re)develop the urban area, there were a lot of new workers needed to build this modern megacity out of the swampy rural area. As the city has grown, it has attracted a new type of migrants to work in the manufacturing industries and later in the high-tech industry. Currently, there is a mix of migrants: factory workers, students, highlyeducated employees and foreigners. Future vision of the modern megapole Shenzhen By 2025 Shenzhen wants to be known world wide for its technology and innovation. They want to invest a lot in R&D to create a modern and sustainably city. “Innovation” is their key word.

The industrial development keeps expanding and many rural migrants start moving to the city in hope for better job opportunities Urban center

Urban villages

The urban area keeps expanding into a modern skyscraper city. The rural villages get dominated by the city and transform in to urban villages

By 2035 Shenzhen will be China’s international showcase as a “modern, innovative and socialist megacity”.They strive to be the capital of innovation, creativity and entrepreneurship. By 2050 Shenzhen will be one of the world’s top cities competing with all other big players. By that time they want to have world influence.

Timeline of Shenzhen’s development Shenzhen – from rural village to the world's largest megalopolis

No urban area in history has become so large so quickly than Shenzhen. A little more than a fishing village in 1979, by the 2010 Shenzhen registered 10.4 million inhabitants. It is easily the youngest urban area to have become one of the world's 26 megacities. In 2017, the Chinese Communist Party also had to take action about the reform, therefore Xi Jinping identified deepening reforms as the next stage. The ‘Greater Bay Area’ was announced within this concept, melting the Pearl River Delta into a single metropolis of unprecedented size. January:

Land use and urban expansion There are three types and of parks in Shenzhen -The forest parks which is an important part of the ecological resource protection system in which construction prioritizes protection. -City park which is important part of the urban landscape that can provide rest, travel, exercise, and communication services. -Community park the nearest open space that provides public services for community resident

Shenzhen was the first Special Economic Zone in China. As its economy has developed quickly, this area has experienced rapid urbanization in the last two decades, changing from a traditional agricultural region to a fast-developing urban region. A previous study showed that in 2005, approximately 39.3 % of the total land was urban area, up from only 3.06 % in 1986.

The social analysis Living in Baishizhou

Demographics Shenzhen

Since the growth of Shenzhen, we’ve seen a striking amount of rural-urban migration. The rural migrants leave behind their agricultural past and come to Shenzhen in hope for a better life. They find employment in factories, construction sites and service sectors. Almost 70% of inhabitants are migrants and most of them live in the urban villages. The Hukou system The Hukou system is a system of household registration used in the mainland of China. Every citizen is registered under a rural Hukoou or an urban Hukou. If you have a rural Hukou, you officially can’t be an urban citizen and you won’t recieve the same benefits. This is the case for many migrants in Shenzhen and other urbanized areas. They can’t rent housing in the modern part of the city and it’s forbidden for them to buy a house in urban areas. Almost all migrant live in urban villages to escape their Hukou status.

KNOWLEDGE BASED METROPOLE

Originally, we saw rural migrants comming to shenzhen to work in the labour intensive factories. Over the years, Shenzhen has tried to upgrade itself from a manufacturing based city to an knowledge based megacity. This has caused an influx of a new type of migrants: students and highly educated employees. The manufacturies get moved to the suburban area of the city and make place for high-tech developments.

Oversaturated urban fabric Due to the rapid economic development, Shenzhen and the urban villages have experienced a social, economical, cultural and architectural transformation. “The big city” has swallowed up all the open space and rural villages on its path. “No more buildable space” Shenzhen has ran out of buildable space for urban expansion but at the same time their is still a big influx of new inhabitants. They start to focus their spatial development on existing build-up areas: the urban villages. Megacity vision If the government and powerfull upperclass had it their way, they would completely demolish the urban villages and replace them with new formal urban neighborhoods characterized by skyscrapers and other modern infrastructures. There will only be space for the urban Hukou and the migrants and lower class will have to leave the city.

elements of collective publicness

Before Rural villages with farmland

Current situation The modern megacity has grown over the rural villages. The villages expanded into dense urban villages with poor infrastructure and unqualitative space.

Future vision* The modern megacity has destroyed the urban villages. They’ve done a complete tabula rasa and started building new skyscrapers that’s of the same scale as the urban area.

Problems in Baishizhou Poor living conditions No time and space for leisure No interaction between locals and migrants Barrier by cultural differences

Exclusion of Baishizhou The government has neglected the two most vulnerable groups: the poor inhabitants and rural migrants. They see the urban villages as a “management problem”. For the local residents, urban villages are considered “backward places” which no longer fit in the modern megacity. They look down on migrants and try to exclude them from all the urban activities. Because of their Hukou status they are rejected from all official urban residences. On top of that, migrants don’t have time and money to enjoy the cities (expensive) facilities and are excluded from social activities as well. They only use public transportation to go to work and return home to the urban village.

Housing conditions

Factory workers, students and new higly educated employees all live in Baishizhou because of the cheap rent. Unfortunatly, they live in really bad conditions. They are overpopulated, over developed and lack basic infrastructure. The urban villages have a building density higher than 70%. They are composed out of multi-story buildings, small alleys and no public space. There is barely any natural light in the small living units. Because of the little space, the hygienic conditions are really bad. Above that, a lot of migrants only live there temporarly which makes it hard to build social relationships. It’s an unhealthy environment, physically and mentally, to live in. The migrants are isolated from the rest of the city, with little to no space for leisure or social interaction. Inhabitants of the urban village try to hide in their small and dark “homes”.

Large income gap

Rejection, bad living conditions, isolation and lack of social relationships have caused migrants to suffer from mental health issues. How can we improve the quality of life in these urban villages? How can we reduce the gap between locals and migrants? How can we change the modern city’s future vision?

No equal rights A lot of crimes

Benefits of Baishizhou The urban villages are associated with bad living conditions and something old and worn out from the past. They face demolition and are dominated by the modern city. Yet, these villages provide a lot of benefits for the city. They are one of the liveliest parts of the city and provide economic possibilities for newcomers in the city. Without urban villages, where will all the migrants and newcomers go? Instead of demolition, we should strive for new urban planning strategies to improve the quality of life in these urban villages. In return, the urban village will be a dynamic place, where you can enjoy activities that aren’t an option in modern Shenzhen. Everyone, migrants, non migrants, blue collar and white collar can interact with each other. This way Shenzhen can grow into a modern and sustainable metropole with qualitative space and an array of activities for everyone.

Cheap housing Vibrant street life : shops, foodstalls and markets Mix of different cultures Economical opportunities for newcomers Good location Potential to grow with the city when they get some extra care Basis for a good community Bottom up development

Spatial analysis Research on street level in Baishizhou that shows the connectivity, typologies and interactions which create a dynamic but chaotic streetscape.

Spacial Syntax INTEGRATION This study measures the amount of transitions needed to go from one street segment to all the other street segments the network, using the shortest path. The analysis shows (in red) the street segment which are linked with all other street segments in the fewest amount of turns. The regions in warm colours are the most integrated part of the city network, shown in cold colours are the least integrated areas. You can see on the image to the right that most of the urban village is fairly well integrated apart form some regions in the south, north east and east. This has to do with the fact that those regions are limited by the walls of gated communities around them.

The most integrated road in red is also the main route in Baishizhou, connecting the street markets, Tantou square and the surrounding neighbourhoods all together. The Picture on the left shows us how the urban village is integrated in its immediate surroundings. Here it still shows a decent integration into a bigger urban structure. This analysis however is to small to see how Baishizhou is integrated in the whole of Shenzhen However it shows us some important areas, where we can take advantage of, the main most integrated road going across the urban village, gives opportunities to lure people into the urban village. Also the same less integrated regions of the smaller study show up in this analysis. But here you can find even more and less integrated areas in the urban village to the south shielded away by highways and industry and in the south east surrounded by huge gated communities.

These less integrated areas should be looked after, these spaces can become an important working point in the resurrection of Baishizhou. These regions make or break the reputation of the village from safe to unsafe, from dirty to clean. elements of collective publicness

IMAGE 1 Tantou old village, now in decline, but a strong cultural and architectural aspect of the local rural village and Shenzhen as a whole. Like a clearing in the forest the old village gives some rest and openness to the immensely densely populated urban village. The place will be reserved and restored to its former glory and provide a central point in our design.

IMAGE 2 Busy roads can be found all over Baishizhou, but one area stands out the most, the crossroads between two major market streets where all the local villagers get their groceries. One road leads straight out of the urban village and can be seen as an exit, the other however is narrow and leads deep into the urban village itself.

This particular building’ a florist stands out in the urban village. The green flourishes on the facade and porch but has also taken the power lines by. In a city district as dense as Baishizhou it can be physically and mentally relaxing to encounter places like this, the greenery creates for a cooler, cleaner and more comfortable space in the heart of Baishizhou.

In - many spaces the village is “visibly” and physically blocked of from other neighbourhoods. In this specific area the border lies between the village and a big road, this can be seen as a positive border, but the physical connection with the street is completely lost. This connection to integrate the village into the city is necessary without destroying the existing green border.

Main drawbacks - Unorganized parking clogs the street - Fences cut off community relationships physically and psychologically - Sidewalks are messy and lack public facilities

elements of collective publicness

Vehicle Accessible Streets Streets that are accessible by all means of transportation. Buildings surrounding these streets have commercial ground floors and used by street vendors. Width ~ 12 meters

Main drawbacks - Uneven pavement and sidewalk profile creates chaotic environment - Poorly defined streets profile and is inconvenient for vehicles and pedestrian - Lack of urban furniture and space organization

Commercial Streets Streets that are only accessible by pedestrians and cyclist. Surrounding buildings have commercial ground floors and used by street vendors. Width 4 - 6 meters

Main drawbacks - Lack of openness for circulation and expansion - Public infrastructure is poorly organized and leads to sanitary problems - Segregation between front and back side of the building

elements of collective publicness

Handshake Streets Streets that are only accessible to pedestrians and cyclist. Buildings surrounding these streets are mostly residential. Width 5 - 0,5 meters

Main drawbacks - Lack of public infrastructure and greenery - Hard elements and fences break continuity and blocks open spaces - No activities or destination points

CHAOTIC STREET SCAPE Streets in Baishizhou are divide in two types, the bigger streets going trough the whole village and the smaller streets going deep into the urban villages. The first type are mostly big enough for one or two cars and some pedestrian areas along the side. The later are pedestrian and sometimes motorcycle only streets. The big streets are organized in two big parts, first of all the asphalt road and elevated pedestrian areas made out of bricks on the side. Those pedestrian areas are mainly used as outdoor seating for restaurants and cafĂŠs and as extra selling space for shops. The pedestrian areas are elevated one to three stairs high in comparison with the car road. This gives a clear road hierarchy. Despite that their are still problems, mainly coming from the lack of space on these pedestrian ways and the chaotic, unplanned nature of its existence, pushing street vendors and pedestrians on the road an so nullifying the hierarchy it creates, and providing a lack of cohesion in the urban village scaring away tourist and outsiders from neighbouring city parts.

VIBRANT STREET LIFE Because of the immense density of Baishizhou housing itself is as small as possible, this keeps cost down and density high. Consequently life is organised in the public realm. The open spaces are used as markets, extension of private space, for shops and restaurants, for people hanging their clothes to dry,... in the city everything apart from sleeping and showering is done in the public realm. The public spaces becomes the cambre next to the anti-chambre of the small apartments of the inhabitants This spill-over from private life into the streets make Baishizhou a very lively space. People cooking, playing, washing on the street, it gives a huge sense of a tight community. But this also creates a

lot of chaos and even crimes. The village can seem unwelcoming and unattractive for outsiders. You feel like stepping into

someoneâ&#x20AC;&#x2122;s home crossing a private boundary. Walking into their personal space

Vibrant street food

Food as an instigator for social interaction, as a show piece of culture, and as fuel source.

Selling fresh vegetables to make a living for yourself and the family

Using the street as a window for your products and service

Baishizhou is known for its many opportunities when it comes to a food related market. Food is a major site in the streets of Baishizhou, from street markets to street vendors and people enjoying their meals on the sidewalks. This is mostly visible in the bigger streets going trough the village, and is enjoyed by locals and surrounding neighbourhoods. But food isnâ&#x20AC;&#x2122;t only limited to the big streets, it can also be found in the smaller streets all around Baishizhou, their the foreigners donâ&#x20AC;&#x2122;t come that often, and is it more based on the local villagers of the surrounding blocks. All this comes in different sides and shapes into the street life bringing along a whole array of portable street furniture. This furniture is mostly made ore used creative from home made carts to display food on, tables, chairs and even buckets than function as a table or a chair. This makes the public space extremely diverse, and asks for the maximum amount of flexibility. Every inch of the urban village is used for some kind of activity ranging from retail to restaurants to more private activities. Living in Baishizhou is living on the street, visiting Baishizhou is connecting with that environment and taking advantage of the interesting street life.

Food and restaurants as an important indicator of social life in the urban village. Food from all over China can indicate the origins of the immigrants catering to the needs of their own people, using what they know. Looking closely at the cuisine we can determine the main inhabitants of Baishizhou. Local Governments are somewhat in the dark when talking about the ethnicities living in their neighbourhoods.

Spatial distribution Buildings around vehicle accessible and main pedestrian streets contain commercial ground floors. Less accessible buildings are only residential. Historical houses of Tangtou village are located in the centre of the area. There are several healthcare and education facilities around. On the north of the village is Handshake 302- art residence exploring urban villages possibilities.

Building typologies All buildings in Baishizhou share common patterns; That is because they were built in a relatevly short period of time, and under almost the same circumstances. After evaluating the entire area, we focused the analysis on 2 streets (Tianhe Road in this page, Shangbaishi Street in the next), from which we can take the following conclusions.

Main streets: General Characteristics Since we are using as example two commercial streets, all the ground floor levels are occupied by shops. That is not always the case, since there are secondary streets that host exclusively residences. If we take a closer look we can see that in some buildings the business is extended to the second level, but only in blocks that their side streets can host external stairs (see X).

Renovation project in Baishizhou Since 2005, the renovation news of Baishizhou has been fermented intermittently until June 2017, when the draft of Shahe Five Village Renewal Unit Planning was officially issued by Nanshan Administration of Shenzhen Planning and Soil Commission. This reform project, which has been tangled for more than ten years, finally landed. Among them, the most eye-catching unit is the Urban Renewal Unit of Shahe Five Village (i.e., Green Landscape Old Renovation), which is also called the Old Renovation Aircraft Carrier of Shenzhen due to its large size. The plot is bounded by Huaxia Street in the east, Shennan Avenue in the south, Shahe Street in the west and Xiangshan West Street in the north.

Baishizhou 5 villages Urban Regeneration Research Studio: URBANUS, Shenzhen, China Category: Urban Design & Research Principal Architect: Meng Yan, Liu Xiaodu "To further explore the issues of urban villages, URBANUS launched the research on the regeneration of Baishizhou Five Villages in 2011. URBANUS tries to study the development of post urban villages and the typologies of hyper density architecture so as to propose a development plan that is creative and responsive to social conditions and future needs. In this research, we studied the urban fabric of Baishizhou and adopted the strategy of reallocating the architectural space based on functional zones. In addition, URBANUS studied the typologies of hyper density architecture specific to each zone and included the typologies of new compensation housing, innovation apartments and super high-rise buildings. Particularly, URBANUS proposed to set a buffering zone in between different zones in order to release more urban space as well as to explore new ways to preserve the buildings in urban villages. Baishizhou Five Villages Urban Regeneration Research is the starting point to a series of research on development models in post urban villages and we hope to use this research to explore a new model for re-urbanization in the context of urban heterogenization." --introduction by URBANUS

THE PRESERVATION MANIFESTO In the blink of an eye, Shenzhen has become a leading metropolis that keeps growing everyday. Rural farmers make place for the high-tech city and it’s new inhabitants. In only 40 years, Shenzhen has become the home of laborers, manufacturers, developers, scientists, entrepreneurs, students and anyone hoping for a better future. With it’s 69% migrant rate, Shenzhen is known as the migrant city. The rapid urban expansion has caused a very interesting urban fabric. As previously mentioned in our analysis, the urban villages are surrounded by the hyper modern metropole which causes many different, but interesting, tensions between the two identities. Because of the rapid and unique urban development in combination with the large influx of migrants, urban villages have become the center of diversity. There is a mix of different cultures, types of inhabitants, shops, food, activities, ... the list goes on. There is a dynamic streetlife which you can’t find in the ‘modern’ part of Shenzhen.

Why aren’t we aiming for reconversion instead of demolition? A complete tabula rasa would solve the issue of ‘bad infrastructure’ and seems like the easier option. But clearly, this intervention would wipe out an area which provides so many opportunities for it’s inhabitants and has such a richness of culture and activity. Demolition would only be beneficial for the rich upper class but it would be a big loss for Shenzhen. We as architects play an important role in urban planning. Urban planning is very delicate. A small intervention can lead to a big change. It should be done with a certain sensitivity instead of a tabula rasa approach. That’s why we’ve chosen to make a detailed analysis of Baishizhou and developed interventions on different scales to advocate for urban villages. Our individual projects (the following chapters in the booklet) act as a tool to preserve and upgrade Baishizhou, but can also be applied to other villages. Our booklet is a manifesto for preservation, not only for the urban villages, but all urban areas with a certain value which are in danger of being lost as a result of rapidly growing cities. Haven’t we learned from our mistakes yet?

Guidelines and policies

Project guidelines

Remove hard boundaries

Incorporate greenery as much as possible

Following guidelines are kept in mind while detailing each part of the project and for the further development of the urban village

Hard boundaries as fences and walls fracture communities. Removing them will open new spaces for people to gather

Green spaces are absent from the urban village now. Incorporating it in the design will have positive effect for microclimate and image on the space

Connect with the surrounding areas

Reconversion above demolition

Multi-functionality of spaces

Segregated areas increase social segregation as well as have lower chances to develop successful business. Connecting surrounding areas will strengthen social and economical stability

Demolishing buildings is an easy but not environmentally friendly development method. Reconversion above demolition will lower CO2 emissions and embraces value of existing structure.

Multi - purpose use of space allows spaces to be flexible and adapt alterations without additional investments

Location of the individual projects We see the renewal of Baishizhou as a phased proces in need of interventions of different scales. Step by step we would evaluate how the urban village would respond and grow according to the adaptations that have been done. Next to the intervention tools and intervention spaces, weâ&#x20AC;&#x2122;ve each introduced a project responding to different problems that occur in the village. The projects are located on one of more locations on site as a pilot project. Each project has been designed that they can be implemanted in many urban areas, not only Baishizhou. Each project has been designed with a sensitivity for a certain problem and can hopefully bring a solution to many urban issues that we face today.

Introduction to the individual projects The following chapters include all our individual projects. Starting from our group research, we’ve each developed a sensitivity for a certain topic, all focused on public space. Together we’ve created a framework with main principles that give us a strong basis to build or projects on. Later, we have discovered that there are many possibilities to create an urban design. That’s why it was important to us to explore all different ideas and develop them according to our personal view. We’ve created an array of different interventions, each with their own scale and unique qualities. Each project is adaptable and can be implemented in all urban contexts which proves us that a mix of different urban interventions can work together to create a dynamic, healthy and vibrant urban environment.

Inside outside the houses, p 89 by Lin Xiang The story starts from the Tangkou Old Houses, carrying the memories of several generations of indigenous villagers. With the old houses crumbling and handshake buildings around grabbing the land, it’s time to change the existing situation. We take measures to renovate old houses, optimize the layout of buildings, open the street level, as well as create collective spaces. This new stage of life is about to open and more interesting stories will happen inside and outside the houses.

Breathing handshakes, p 123 by Bengüsu Cebeci This project is aiming to reveal the linked potential of the existing vivid street life and dynamic commercial activities on the ground floors by tackling the two major problems of life in Handshake towers. Keywords of the project : natural lighting, rainwater collection, street connectivity and interior connection.

Streetscape, p 159 by Bert Lescouhier The street will be used as a tool for an unified urban village, the continues use of brick will bring attention and a curiosity to the village. Pathways like rivers connect big street with smalls allays, and lead the users deep into the village, showing hidden spaces, lost gems and secret ways through Baishizhou. They will highlight the village and aim for a cleaner and more organised whole, luring people inside.

elements of collective publicness

Common stories, p 193 by Miquel Vilalta Flo Through habilitating the second floors of some key buildings, new and open spaces are created. This gives us the opportunity to create and extra layer of public space in which locals can share their everyday life.

DAYS AT THE COMMUNAL FLOOR. PHOTOCOLLAGE.

Hidden spaces, p 219 by EglĂŠ DrungilaltĂŠ Spaces in the residential parts are lacking light, greenery and a definition of functions. By identifying unused space between buildings and replacing them with a greenery project we can redefine residential streets into a healthy, safe and green environment that stimulates social interaction and public activities.

The green corridor, p 249 by An Gelan Baishizhou is enclosed by hard concrete walls isolating them from the rest of Shenzhen. This border is not only a physical boundary but also a social boundary, separating the urban villagers from other city dwellers. The green corridor transforms the hard concrete border in to a permeable boundary. The green corridor project is focussed on re-connecting space, people and greenery by using vernacular principles on an urban scale.

The urban windcatcher, p 273 by Shaimaa Daweri The main idea is to cool the city by using the principle of wind catchers, inside the open spaces which are connected to small alleys between buildings. This way the unused open spaces will be transformed into pleasant public courtyards. The wind catchers can be seen as a tool to cool down the courtyards and the village but it also acts as an unique public landmark. The urban windcatcher in combination with the courtyards will create a unique experience in side the central patio.

“Cities, Grow in Difference”

--Theme of UABB, 2017

“Shenzhen is the place where lots of people come to reinvent their identity”

--Architect Thomas Tsang

Urban Village is a new style of spatiography that arises in the new production and consumption links in the process of globalization. Urban villages are not concrete villages, it should be called an “extreme”: It does not point to anywhere, it is just an abstract point, and it just happens to be in Shenzhen or it can happen anywhere in Africa. This “point” can link all flows of the world like production flow, information flow. --Architect, Yuxing Zhang

Entrance & Store Property There are two pedestrian ways to the Tangtou Old Houses. Firstly, walk along the back bone street on the north, turning around to the back of houses and passing through two handshake buildings. Otherwise,they are accessible from the main road on the south. By observing the streets and buildings, ground floor along the street are all used as commercial. It is an universal phenomenon that 2 to 4 stores can be accommodated in one building. If buildings are hardly adjacent to the main road or alley, the ground floor is for private use. The upper levels can be rented by immigrants. Therefore, land has been used compactly, with a dense living population. N

Functional Partition of Site In the master plan, the majority of Tangtou Old Houses will be preserved and renovated, mainly as an exhibition space for visitors. Both the illegal buildings on the square and utility rooms in front of the old houses will be demolished, and the bigger collective space will be returned to the public. Considering the seasonly rainy and hot weather in Shenzhen, interior entertainment space will be designed. The three buildings located on the main road will be transformed into a residential, office, leisure and entertainment complex.

Business Model in Houses Business Model in Houses In the existing building, three tenants rent and live on one floor, while sharing the space of kitchen and toilet. Due to the high-density building in the urban village, much internal space in the building lacks sunlight and wind ventilation. In proposal, the quality of living space might be better and livable. Meanwhile, more rooms for new tenants will be designed. Landlords will acquire more rents from the renovation proposal.

In the renovation project, Landlords will get advantages, not only comfortable living space, but also economic benefits. Once these proposals work after practice, more landlords are willing to participate in the urban village upgrade.

Window Sunshade Deisgn Windows and doors are important elements of architecture. In Chinese traditional buildings, they are essential components with both aesthetic and practical functions. The doors and Windows of the building can not only reflect traditional culture, but also a valuable historical heritage. In this design, the sunshade design involves traditional elements and modern material technology.

Window with Chinese style

Traditional Window Ancient windows were made of wood. The windows and doors of residential houses are fresh and elegant in color, while palaces and temples are decorated with multi-color painting technology. Windows were decorated with different patterns, coming from other decorative arts, such as patterns of bronze ware, patterns of ancient jade ware, and patterns of textiles,etc.

Window Sunshade Deisgn Considering the climate in Shenzhen and economic benefits, aluminum was chosen as the material for the sunshade panels, which are hung outside the building as the second skin. Pattern design can reduce heat gains and glare whilst maximising the use of natural daylight.

Construction Detail Concrete Wall Steel Pole L Profile of galvanized steel

Advantage to use metal shading design Aesthetics Metal offers a unique, rhythmic aesthetic to compliment. With virtually options in hole shapes, sizes, traditional patterns, perforated metal makes it a perfect material to achieve a specific look.

DurabIility It can withstand harsh weather environments, with the ability to control or equalize pressure due to its high strength-to-weight ratio. The pattern design also decreases the weight.

Energy Efficient By balancing light & ventilation, perforated metal can allow architects to manage interior heat build-up from the sun.

Eco-Friendly Due to its recyclability, it reduces energy in use, promotes sustainability, and invites innovation in terms of innovative & creative design. Reduce weight and lower fuel transportation costs to the building site.

Sunlight & Ventilation The sun shading design is equipped with an electric device, which can adjust the angle according to the height of the sun. It can effectively block heat directly into the room,while ensuring adequate indoor light. Decorative traditional pattern design, not only can create rich shadow images, but also conducive to the circulation of the air. In the hot and humid climate of Shenzhen, the design of the sunshade makes the space more humanized and livable. 90째

CONCLUSION Urban villages are like a big family, showing strong tolerance for immigrants working in Shenzhen to seek for a better life. Houses inside can provide warm shelter, while the outside is more collective. Inhabitants can chat with friends, tasting foods, etc. However, many voices from authority are now inclined to demolish villages and replace them with modern high-rises. From my perspective, It is a kind of abnormal urban aesthetics to pursue the uniform appearance blindly and ignore the diversity of life. How do cities grow in difference is a critical issue to explore.

business owners & landlords

• The economic value of Baishizhou is mostly created by the commercial activity on the ground floors of the buildings. Looking at the existing shops1, it is clearly seen that most of the economic gain comes from retail and accomodation services. Open urban grounds are a design that can benefit both business owners, landlords and urban villagers. It will both strengthen the commercial and touristic value of the village with its new street charm and help develop and modernize the area without causing gentrification by initiating a slow renewal. 1 • Retail & Wholesale = Store Quantity: 974, Store Percentage: %42.16 • Food & Hotel = s.q.: 552, s.p.: %23.90 • Residential Services = s.q.: 615, s.p.: %26.62 • Other Services (related to residential) = s.q.: 37, s.p.: %1.60

Also, secondary important axes observed are surrounding the red axes and, strengthening the general proximity. Thus, a conclusion can be made that opening up the ground floors will contribute to the walkability and the strengthening of the commercial activity on the ground floors.

ECONOMIC & SOCIO-CULTURAL BENEFITS OF NEW CORE DESIGN: Is it possible to compliment and revitalize an ancient courtyard culture in extreme urban conditions?

• central cores in handshake towers are already holding great importance as the landlords change the interiors very often to gain more rent profit

• improved living environment with climate integrated building cores and open ground floors • renewed centered core which will make future refurbishments and new floor additions easier • if new storeys will be added, the core and water-sunlight tunnel can be lenghtened and keep providing for the future residents • landlords will have the chance for gaining more long term renters or even buyers who wants to enjoy a nice neighborhood 141

Conclusions Although the future of Handshake Towers does not seem very bright, total demolition is not a feasible and humane solution. The displacement of a large number of people will cause sociological and urban problems as well as the loss of enormous potential which urban villages obtain. It is clear that Shenzhen is turning into a busy metropolis full of skyscrapers and the Handshake Towers will have to adapt to this change one way or another. In this project, it is questioned that if it is possible to reveal the potential of the urban villages by enhancing the urban conditions and therefore, catalyze a slow, steady change from the bottom to top. Refurbishment over demolition will support a more diverse community in which everyone feels belonging.

They will highlight the village and aim for a cleaner and more organised whole, luring people inside.

VIBRANT STREETSCAPE Street life is an important aspect of life in the urban village, our research pointed out that streets are used for almost everything apart from sleeping, showering,... This makes the public spaces extremely important and asks for a well-organised structure, that is clean and is used to its full potential. A unified street scape -is a first step in the organisation of the immensely densely populated urban village. Providing structure pathways and hierarchy without losing the vital characteristics of the urban village in its current condition. Paths will flow like water deep into the urban village and -allow the visitor to discover hidden squares, restaurants, religious shrines, old wells,... These pathways will be surrounded by greenery cooling down Baishizhou and making it a comfortable and relaxing town to be in.

The wave pattern thus created resembles waterways passing through the urban village leading people around with a sense of being on a journey. The paths seemingly merge into each other and invite the participant to explore the area as he likes. The streets flow like water through a forest of buildings, resembling softness, flexibility, calmness in the Chinese philosophical scope of Daoism.

The lights provide light and an extra surface of greenery. Ivy is placed into the village and grown over buildings and â&#x20AC;&#x153;powerlinesâ&#x20AC;?. These green surfaces up in the sky should furthermore lead visitors into the smaller streets of Baishizhou and give a more mystical green element into the densely populated village.

Common stories The urban villages historically lack an essential space for the developement of a healthy community: The public (but secondary) squares. A place slightly isolated from the main, impersonal streets, where the neighbors can get together and create bonds with whom -and what- surrounds them. By creating a network of connected second stories for the residents, we are also allowing new, intermingled narratives; weâ&#x20AC;&#x2122;re making possibe the establishing of common activities and, of course, common stories.

Common stories 5m Avobe Ground Since the main goal of the intervention is to preserve and improve the actual urban tissue, a solution that involves the opening of the second floors of the building has various advantages: By using the floor above the ground level only, which was previously occupied by apartments, the losses on habitable space are minimal in comparison to the gains on the life quality. If we take it from the landlordâ&#x20AC;&#x2122;s perspective, the economical advantages that this intervention gives are also remarkable, since it allows a reavaluation of the building value and the establishment of new small business

Another clear advantage is the simpleness of making accesible the second level to the public, in comparison to the levels above. Furthermore, and as can be seen in the typological study of the buildings on the area* thereâ&#x20AC;&#x2122;s already a constructive culture on installing external staircases, as well as bridges between close buildings.

KEEPING THE BUSINESSES OF THE GROUND LEVEL The small shops and business that are already in the area not only will be unaffected by the expansion of the public space, but they will benefit from it since it will make the inner streets more busy. 196

elements of collective publicness

Giving to the first floor a special use is a common practice in the area; The phenomenon of staircaises in the outter part of the building is not rare to see in Baishizhou. They normally lead to a small shop or business, or even to an independent flat.

Common stories Concept

NEW SPATIAL POSSIBILITIES Architecturally speaking, thereâ&#x20AC;&#x2122;s a trait of particular interest when doing this approach: The experience of the city public space from a completely new point of view is suddenly possible, and that offers plenty of potential outcomes. At the moment of conceptualizing the space, that was the main point that we had in account. How do we give to the people of Baishizhou a new way of experiencing the urban village? What de they need the most in that particular enviroment?

THE STREETS VERTICALITY

THE CHOSEN SOLUTION IS CLEAR AND SIMPLE:

HORIZONTALITY IN THE 2NDS

HORIZONTAL PERSPECTIVES. In a place like a urban village, their inhabitants, used as they are to crowded streets and stuffed buildings, only have the feeling of looking into an open space when watching the sky. Our intentions in the developing of this project is to give to the people the chance of feeling the profundity, the horizon, also in the horizontal direction, thus enhancing even more the feeling of freedom even in a dense place such as Baishizhou.

199

Common stories Design methodology To reach our objective we created a method for a systemical intervention: That is to say, this model is applicable regardless of the particularities of each building, and can be used for the entire urban village. That does not mean that the final product will be always the same, or that it will not contemplate the enviroment, since through the method proposed the results are different precisely because of the context. In order to explain it, weâ&#x20AC;&#x2122;ll use a particular area in the center of Baishizhou, an extremely densified zone. Through this most extreme case we will be showing the principles for the creation of common stories. The first steps are focused towards creating sensemaking public spaces in the seconds. For this, what weâ&#x20AC;&#x2122;ll need to start doing is grouping the buildings. That has two reasons. The first is the need of creating spaces in which is possible the coexistence of different activities, and for that they have to achieve a certain size. The second is that, by creating building agrupations, we can somehow redirect the circulations inside the village, enhancing the importance of some streets while hiding some others.

COMMON STORIES_USER MANUAL

共同的故事_使用手 STEP 1 (步一)

Measuring width between buildings In order to decide which buildings could or should be connected, it is of outmost importance to know the spatial relation between them. Therefore, the first step is measuring the distance that there is between all the objects (buildings). Throughout the urban village, there are already cases of interconnected buildings at the second floors. After analysing them, we discovered that there was never more than 3 meters between the linked buildings. In the project we will abide to the same rule, achieving through this limitation constructive coherence with the enviroment.

STEP 2 (步二)

Defining circulations through the cluster Considering the circulations that we want to generate inside the area is a key point as well, since it reduces the randomness of the grouping and makes it useful on the urban scale. If we don’t want to interfere with these circulations, the building agroupations should avoid cutting over the main routes and serve as “rails”, directing the people towards the planned places.

STEP 3 (步三)

Grouping

Once the two first parameters have been taken into consideration, the obvious result is a continuation of interconnected buildings at some points quite short, at others impressively large. With this last step what is achieved is the regularisation of the size of this spaces, by limiting its area to a certain amount of square meters. The advantadges of doing so is that we make the spaces local, private to a certain extent, and easily comprehensive in its entirety for everyone. The maximum area that we admit is 500 sq.m. , and the minimal 150. That means, in most of the cases, agrupations from 2 to 3 buildings. 201

步三 3. Grouping Plan 1. We can see how small are the gaps between buildings. Even though most of them are closer than 3m from each other, we can already discard some connections that won’t be possible if we follow the principles. Plan 2. The movement flows can be understood in a clearer way if we see it in a wider -urban- context. The Y axis would serve as a part of the main avenue planned (see masterplan), while the X would connect the squares (blue) designed in the project HIDDEN SPACES. Plan 3. Marked in grey, the groups of buildings that will be detailed during the project (A,B,C,E,H,I,J).

In the case of G and K, it is due to its different programme and working principles that will only recieve a brief comment (see Annex). Image. Stadshal, Gent. This multifunctional space is shown to make visually understandable the chosen average size for the agrupations. The size of the Standhal is of aproximately 350 sq.m. Photographed by Marc de Blieck © Robbrecht en Daem.

203

Common stories Design methodology

With the building agrupations generated, we proceed to the next steps, in which we zoom in the scale to detail the buildings. Horizontal perspective is the spatial charachteristic that we want to achieve, and therefore all the gestures will be made towards this same purpose. We have to remember though, in the masterplan scale, the importance stressed on the preservation of the buildings as they are. Due to this, we start only by emptying the interior of the building, and leaving the naked structure and together with the outter facade.

Process sketched on a hypotetycal building. Avobe: It illustrates the floor, once emptied of everything apart from its skin -facades- and structure. Middle: The building, once the perspectives are opened (Step 4). Below: The possibilities when defining the internal divisions (Step 5) are multiple. As can be seen, starting from the structural pillar,the wall can go in one or both directions.

PART 2

Opening perspectives The coming intervention may be the most important of the entire project. It is the substraction of entire parts of the old facade in order to get the desired horizontal perspectives. This obvertures are placed only in the areas where, by taking the wall out, we get far-range visuals; That is to say, in the places where the building is facing a perpendicular street or a square. It is also the moment to take out the walls in the inner part of the building agrupations, so each common storey can be understood as single unit.

STEP 5 (步五)

Defining internal divisions Once the openings towards horizontality are done, we are left with an empty space, filled only with the structural pillars. Pillars, by definition, are purely vertical elements, and therefore in basic contradiction with the main concept of the project. It would appear as if we were in a dead end: How to make sense out of this paradox? The answer is by transforming them in walls that direct your sight to the openings. With this solution we enhance the impression of perspective and we create some new aparent divisions that are bound to give even more plurality of uses to the elevated square.

STEP 6 (步六)

Texturing the interiors Getting to an even smaller scale, what is left is to define the materiality inside the building. It will be completely focused towards enhancing the characteristhics proposed for the building, by using the most accesible materials in the area. We assume for this part that the most accesible materials are the ones that are used the most -something that we already know after the urban village analysis-. 205

The resulting product is finally put into context, and the stairs leading to each cluster can be finally located. By merging it with the Hidden Spaces project, we create a continuous public space that combines the two levels. The location of the accesses is something that haven not been neglected. They are placed in order to create intimate but clearly public alternatives, not forcing the visitor to go in but nevertheless visible from the main circulation routes.

ยบ

REINFORCE_THE_ CONCEPT_BY_ REINTERPRETING _ L O C A L _ CONSTRUCTIVE S O L U T I O N S Following this idea, each one of the elements inside the project gives consistency to the rest of them. For instance, The interior walls are made with concrete bricks, the most accessible & cheap among the materials. By placing them in the perpendicular way, in a way that the light can get through, we are lightening their denisty, and even though from some perspectives the wall will keep directing your sight to the horizon, from others it will allow the individuals to see through them. When refering to the treatment that recieves the facade, we left them as it is, since modifying it would mean to destroy the relation of this flat with the rest of the building. Nevertheless, since it was necessary to blind the old windows -they would diminish the impression of the newly opened perspectives- we place a second skin in the interior made of translucent polycarbonate. With this, the sights are blocked but the light still can get through. Pictures. Prototype; More than to generate an accurate model, that was made in order to see how the light would interact with different materials and patterns

211

Âş Common stories Materiality The treatment of the floor is also a good example of applying the main concept through the local conciousness and materials: We have seen already how all the facades of the urban village are covered with ceramic tiles; since this material is only used to cover vertical surfaces, by using it to cover some parts of the floor weâ&#x20AC;&#x2122;re taking the concept of horizontalizing to its most tangible level. Folding the skin of the building is, in a way, rotating by 90Âş the essentialy vertical Baishizhou. Practically speaking is also advantageous, since the reflectiveness of the ceramic will make the Common Stories lighter and its thermal properties will help regulate the temperature

Common stories Annex

The project has been focused towards creating intimate public spaces. Nevertheless, the systemical approach proposed can be extrapolated in almost in its entirety to different programmes as, for example, a shopping avenue or a comercial cluster. Although this options were contemplated already when the project began, it seemed more reasonable to focus only in one set of functions and develop it as extensively as possible. We keep them, in any case, as possible directions for further developing the Common Stories.

Plan 1. The approach is taken to a bigger scale, measuring from top to bottom the width of a street in Baishizhou and the distance between contiguous buildings. The data shows clearly the importance of widening this route, wether in the ground floor or -as we propose - through the seconds.

Plan 2. This would be the parallel to the 3rd step (Grouping) of the project. Once we have the clusters in which the buildings are grouped (by following the rules stated at the beggining) we see that there are some agroupations that do not fit into the size requirements. Those, as would be the groups K and G of the current project, would be adequate to be shopping malls (darkest blue in the diagram) or secondary avenues (cyan).

In the parts where the width is of 1.5 or less, itâ&#x20AC;&#x2122;s basic to have also an open ground floor ( as included on the masterplan).

Square A This square can be approached from 4 different directions. It contains 3 elevated flower beds on different sides and paths that connect on the middle. The idea was to break straight axis with greenery that would grab an attention of a pasN senger and force it to come in through the middle of the square where are stairs leading to the common floors and playground for children

241

Hidden spaces - square B

Square B This space is composed from two opposing staircases leading to communal floors. Additional to the staircases there are small amphitheatres facing green pocket with a N playground in the middle. Staircases are connected by the laundry lines providing a necessary function and additional shading to the playground

The green corridor Currently, the urban villages donâ&#x20AC;&#x2122;t fit into the vision of thriving Shenzhen. As a result they have build a hard concrete border, which has caused a physical and social divide and has left Baishizhou isolated from the rest of the city. Situated on the southern edge of the urban village of Baishizhou, the green corridor aims to reconnect the urban village with the modern megapole Shenzhen by replacing the border with qualitative public space.

THE FUNDAMENTAL RIGHT TO PUBLIC SPACE

251

The green corridor

EXISTING SITUATION Surrounded by gated residential areas, an amusement park and a luxury golf course, Baishizhou is struggling to survive in the fast growing metropole Shenzhen. Unfortunatly, the ‘new and modern Shenzhenners’ don’t like urban villages because they see this as something backwards and outdated, that doesn’t fit in their vision of a thriving high-tech city. As a result, Baishizhou is enclosed and isolated from the rest of the city by concrete walls bordering the village. Because urban villages are well located within the urban fabric, they are the target of demolition and renewal used for new skyscrapers only benefiting the richer population. The hard boundary has disconnected the urban village with the rest of Shenzhen. Inside the village there is no greenery or public space. Yet, next to the village there is an abundance of open space which is not accessible to them. How can we fade these existing borders which have created not only a physical divide, but also a social divide between different groups of residents?

252

elements of collective publicness

RE-CONNECTING The green corridor is focused on re-connecting Baishizhou with its surroundings and the rest of the city by creating a permeable border structure that opens up to the outside, yet it still gives the urban village a feeling of security. Because the green corridor is located in the South of the village, next to the busy Shennan Avenue, it will act as an entry to the urban village. By creating this permeable structure as a public space, it will generate a lot of activity at the border of the village re-connecting all different residents and visitors. The green corridor provides a real opportunity to experiment with urban planning. Itâ&#x20AC;&#x2122;s not only important to design the permeable structure but also all the space surrounding it to create a qualitative addition to the urban fabric. Because of the location of the corridor, a nice inbetween space is created between: the houses of the urban village, the public space, greenery and the corridor. The green corridor: re-connecting people, spaces and greenery by using vernacular and sustainable principles.

The 4 project fundamentals

1. Agriculture inclusive urbanism

2. Vernacular architecture

40 years ago, Shenzhen consisted out of fishing farms and agricultural land. Today, we know Shenzhen as ‘the large metropole’ without even a trace of it’s agricultural past. The migrants who come to Shenzhen left their rural backgrounds in hope for a better future. Currently, we’ve learned the many challenges of our food resources, production and transportation. It’s time to introduce new ways of local and sustainable farming that fit in our urban fabric.

The chinese culture and architecture has already existed over a millenia. Known for it’s flexible design, hierarchy of spaces, courtyards and passive cooling techniques, we should safeguard these traditions. This project uses the Siheyuan as an inspiration for interconnected courtyards and hierarchy of spaces on an urban scale. These spaces should act as communal spaces connected with nature.

3. The urgent need for public space

4. Reconnecting

The modern part of Shenzhen has an abundance of safe, green and pleasant public spaces. In the urban village there is not one qualitative public space where people can come together. This causes social isolation and negligence of the open space. Currently, the ‘outdoor public space’ is dark, unhygienic and unsafe. We see public space as a luxury but it’s a fundamental right for everyone. We should create open and safe public spaces which will create a healthy living environment.

There is a clear physical and social divide between urban villages and the modern part of Shenzhen. They have literally build a wall around the villages which makes the gap between different social groups bigger and bigger. How can we reconnect the urban village with the urban fabric of Shenzhen and how can we bring all inhabitants back together? The project is focusses on breaking boundaries and making connections on a physical, social, environmental and urban scale.

The entrance to Baishizhou acts as a connecting point of the different urban interventions, creating a vibrant public space where everything comes together. Physical and social connections are necessary for a healthy, safe and pleasant urban fabric.

The modular structures catalogue For the green corridor project it was important to create a public infrastructure which is easy to assamble and inexpensive to proof that you can create qualitative interventions without big investments, only by using a well thought out design. This is a motivation that even small interventions can have a huge impact on the urban life quality. By using modular structures, the design is flexible and can be placed in any type of context. These structures are also sustainable because they can easily be reused and produce less waste then traditional structures. The mix of different infills of the structures create an interesting urban intervention, which makes it a pleasant experience for itâ&#x20AC;&#x2122;s users .

Flat roof structure The flat roof structure was the first structure created: a wooden frame with a floor surface and roof surface. To guarantee a feeling of privacy and safety for the inhabitants in the semi public courtyards, there is a net provided where plants can naturally grow on. This also gives an enclosed feelings for people using the green corridor. There are different variations on the basic structure: the green roof structure, netted structure and first floor structure. The first floor structure can be used to maintain the green roof, create an extra layer of public space or to connect to the first floor of a building.

Sloping roof structure The sloping roof structure will guide rainwater directly to the aquaponics pond and surrounding greenery. Because it opens up more to the forest side, it will give you the feeling youâ&#x20AC;&#x2122;re walking inside the forest while still being covered. A variation of sloping roof structure is also used for the round public square.

The soft border structure The soft border structure is located between the public square and semi public courtyards. Because there will be a lot of activity and passage around the public square, it’s important to provide some privacy to the inhabitants using the semi public courtyards. Even though it’s a border between public and semi public, it was necessary to also give this border a connecting function. There is seating provided on both sides of the green border and you can still see a glimps from who’s on the other side. There will also be an information board where you can see activities that are organized and they can also give information about the green corridor, aquaponics, Baishizhou,... and so on.

The round public square structure Based on the principle of the sloping roof structures of the green corridor, the roof of the round public square slopes inward, providing the plants inside of the square of water. It’s necessary that the round public square provides shading because the sun and heat in Shenzhen can be unbearable.

Itâ&#x20AC;&#x2122;s a real playground for public events, activities and gatherings. You can sit and relax on the stairs in a shaded environment while enjoying the greenery and activity that takes place in the circle. The round shape of the square subtly guides passersby around the public space. The public square is the social connector of the village.

The semi public courtyard

The semi-public courtyard The courtyard originated from the inbetweenspace between the green corridor, the public square and the urban village. This courtyard is a place for the inhabitants of the urban village, where they can relax and meet in a more private and green environment. The soft border created by the nets and plants gives them a safe and enclosed feeling while still being able to get a glimps of whats happening in the public square or green corridor. Based on the principal of vernacular architecture, these urban scaled courtyards provide passive cooling for the urban village. The aquaponics pond lays inside the courtyard which also creates a soft border between the courtyard and green corridor. The water provides extra cooling and provides a fun and relaxing enviroment. The courtyard is a place where the inhabitants of the urban village can truly relax in a green oasis. 268

Detailing the soft border

The soft border While the project focusses on removing existing borders, itâ&#x20AC;&#x2122;s still important to provide inhabitants with an enclosed and safe feeling. The soft border, created by a net with plants, protects the urban village from the hustle and bustle from outside the village such as the busy Shennan Avenue, the crowded public square and the passage on the green corridor. Creating a new type of border, which still lets everyone have a look whats laying behind it, peaks and stimulates curiosity. The soft border still has a connecting function by providing a sitting area on both sides. The information board is inspired by the previous use of the hard concrete walls: on the walls people would place advertisements to inform everyone of available housing for rent. Now, the new soft border also has an information board where everyone can get informed on the social activities or they can get more information about the green corridor project with all itâ&#x20AC;&#x2122;s public functions.

elements of collective publicness

Conclusion With cities, growing from farming villages to global metropoles overnight, we seem to have lost touch with creating qualitative (urban) spaces. The green and public space only seems available to people living in the modern part of the city. While the urban villages get overcrowded and to dense, the rest of the city makes it impossible for the urban villagers to find a place to escape for a moment. Modern Shenzhen seems to turn a blind eye to the urban village and itâ&#x20AC;&#x2122;s inhabitants. Yet, they have forgotten how rich of culture and opportunities these urban villages are. We as architects can play an important role into the change of the urban fabric. Starting with a small intervention on the border of the urban village, we can try to re-connect the physical and social connections. By creating mutal benefits, we can change the outdated opinions of urban villages and other urban contexts. Everyone deserves a safe and healthy living environment which means everyone has the right to a qualitative public space.

The urban windcatcher In Shenzhen, the wet season is hot, oppressive, and overcast so the idea was to cool the city by using the windcatchers inside the courtyards with the small Alleys between the buildings, The wind catchers is in combination with an experience in the central patio.

Demolishing strategy and courtyard creation The development strategy intention to preserve and renovate the existing buildings and not goes in the demolishing direction,for the courtyards creation some buildings should be demoilshed to have the opening between the buildings. The demolishing strategy is focusing on the old and low height buildings (buildings less than four floor heights ) and avoid the hight and new building demolishing. As the diagrams shows the demolished buildings and the new buildings that should be added to create the courtyard area.

276

The alleys networks where all the courtyards entrance open to it, The alleys are a one way car roads connected to the main road in the urban village so all the buildings have accessibility to the roads. The windcathers placed in the middle of the courtyards and oriented in a way that all the airs moved from the courtyards towards the alley so we could create a kind of air circulation in the urban village.

279

The windcatcher orientation The idea is to have a windcatcher inside the courtyards, As a monumental element in the middle of the courtyard to cool the courtyard and the surrounding buildings. The windcatcer opened to two directions, in the direction of the prevailing winds in Shenzhen.

The windcaher must be higher than the surrounding buildings and they should not be in a singel line or parallel, but rather they must be seperated and of different heights.

280

elements of collective publicness

The windcatcher should be Oriented in a way that the cold air goes toward the alley through the courtyard entrance and the surrounding buildings should not block the air flow,The buildings also can contribute by orienting the existing air from the courtyard.

281

windcatcher Idea The Idea is to have a windcatcher in the middel of the courtyard to ventilate the surrounding buildings with a water pool to humidify the air that comes out the wincatcher. In addition to cool down the air the pool will be as a fishing pool so it it can add activity to the surrounding areas. In addition to being a common space in the middle of the courtyard , it can be used to collect the rainwater in the winter.

283

The windcatcher connection with the surrounding buildings The windcatcher is linked to the first floor plan in the surrounding buildings by a light structure stair so the user can enjoy walking around it and experience it. while the first floor area is a common space between the buildings with different activities such as gym, internet bar, restaurant , meetings spaces, offices and workshop spaces.

284

The courtyard area is shaded by the surrounding buildings and in these shaded areas people can gather and sit there and enjoy the cold air that comes out the windcatcher. The fishing pool in front of the windcather where the people can enjoy fishing and having an unique experience in the central patio.

285

Water Circulation The idea is to link between the pools so we have kind of a canal in between and by having a slope between two pools then we can control the water flow. By providing a collective point where all the water will be collected and from that point we could return the water again to the first pool These canals can help to decrease the air temperature of the city

Facade Strategy Bringing back the vernacular Architecture theory that can work with the courtyards and the wind catchers ideas such as the Mashrabiya ideas and its functional such as: light control, Air flow regulation, Humidity control, Temperature Regulation, and visual privacy.

MATERIALS Natural fibres have showed to have a high capacity of heat absorption. If they are kept in their natural colour,due its lightness they have a high capacity of sun reflection, beside plants like rattan, agave and jute can be reproduced beside the rivers in China, generating a cycle of activation of the local economy.

Conclusion The urban villages are vibrant areas, rich of cultures and provide and array of opportunities for people comming to Shenzhen hoping for a better future. The bottom up planning has created an unique urban fabric that has peaked our curiosity. But unfortunately, these overcrowded, unsafe and sometimes squalor villages have some social and structural problems. This is why they face demolition this present day. We chose the path of conservation and upcycling of the urban village while keeping population density at its current level but making it a more liveable enviroment. We reconvert the apartments lacking basic infrastructure and add a more diverse use. The village gets upcycled by the reconstruction of the ground level, opening up spaces, remodelling the surface and adding greenery. By opening up and connecting spaces we create different layers of qualitative private and public spaces. The main goal is to accomodate the urban villagers but also including people from outside the urban village. By creating spaces for everyone, we create mutual benefits which ensures the existence of the urban villages in the future. Our projects focus on different elements of the urban village and they exist in different scales but all off them are based on the principal of flexible spaces that can adapt according to the use, keeping in mind that space functions can change over time. We create designs that make room for the bottom up approach which unfortunatly has been forgotten in modern megacity Shenzhen.
