CONTEXT GEOGRAPHICAL & HISTORICAL CONTEXT
‘COLLIDE’ As a cities population increases, so does their consumption of land and resources. Coupled with a growing culture of consumption, the need for effective waste management and alternative energy production are vital mechanisms required to sustain cities in the future. Shenzhen’s astronomic evolution from a small agricultural market town to global economic powerhouse is evident in the monumentality of its skyline. Within its relatively short history of economic and cultural expansion, the urban village has acted as the host for the hoards of people coming to Shenzhen to contribute to its booming and emerging industries. Evolving from small fishing villages into hyper dense communities, the Urban Village is an important and consistent feature of Shenzhen’s ever changing landscape. They provide affordable housing for the growing migrant population and foster a culture of creativity and collaboration for emerging industries. However as land availability reduces and prices increase, the built environment continues to tower above these communities or they are demolished from the landscape for new development, impacting land use diversity. ‘Collide’ aims to liberate the urban village by making them more sustainable, self-sufficient and integral to the city. Considering place making, renewable energy production, and social utility promotion as strategies to address the current perceptions of their place and value within the city. Located on the perimeter of the Gangxia urban village, south-east of the Futian District CBD, Shenzhen, China - the proposal aims to reconnect the
urban village with the city through the combination of its complimentary hybrid function built form and village gateway promenade. The function of the facility combines programs that conflict in their practical use, but are complimentary in their fundamental concern with the process of purification, forming a harmonious hybrid. A waste to energy plant that uses the process of anaerobic digestion to process the food waste of the Gangxia urban village and local residents to produce biogas which is used for power and heating within the facility and provided to Gangxia residents through a waste for battery energy scheme. The experience of this component goes beyond its perceived industrial quality by making the waste to energy process a theatrical experience that serves as an educational tool, teaching about renewable energy production and environmental sustainable design. Additionally, the energy produced powers the facilities other function, a bath house that is open to the village residents and general public. A place for leisure, social engagement and private relaxation. Spatially the relationship between these functions provides controlled glimpses between through an interlocking of the built form. At the ground plane, the facility is accessed by the Gangxia gateway promenade. A place to meet, gather and be drawn into the experience of the urban village. This space attempts to provide a landmark, a sense of place, a reason to go there, that is intrinsically tied back and integrated with the Gangxia. Within the broader context this proposal aims to offer a model that can be adopted by other urban villages throughout Shenzhen, to make them more of a utility within the city.
CONTEXT Gangxia, like many other Urban Villages was once a small agricultural village from which the modern city grew. Located in southern Guangdong province, just to the north of Hong Kong the environs of the village and the Futian district more broadly have changed significantly, from paddy fields to industrial parks and now to Shenzhen’s central business district. In 2008 Gangxia’s indigenous population of approximately 900 possessed more than 500 dwelling buildings over 0.23km2, accommodating nearly 100,000 migrants, and many commercial activities, with nearly all of its communal land being acquired for formal development. Most of Gangxia’s tenants work in the city outside of the village, with village revenues generated predominantly through private dwellings. Although the indigenous villagers and landlords of Gangxia are relatively wealthy due to private sale and land division, their village community have little sway economically and politically. The fragile social cohesion of the community
makes the negotiation processes difficult when facing the pressures of redevelopment from the district government and land developers. This pressure coupled with an overall public perception that suggests Urban Villages are unsightly and an inefficient use of land makes them quite attractive, however the development of these villages like Gangxia can significantly impact the diversity of land-use and accessibility to affordable housing within these areas. Furthermore, the highrise buildings that replace these unique communities add to an increasing sense of homogeneity across the urban fabric. In 2010, the western section (Heyuan) of Gangxia was demolished and is currently being redeveloped into shopping malls and high-rise office and apartment buildings, leaving only the eastern section (Louyuan) of this important historical site remaining, with pressure mounting over the Village’s future. A significant aspect of the clients initial brief stipulated the need to address this, by highlighting the important historical and cultural value of the site through a design solution.

CITY
DISTRICT
Shenzhen is situated in southern Guangdong Province of China, Shenzhen operates as a major financial center in China that also borders Hong Kong, acting as a gateway between the two countries, demarcated by the Shenzhen river. In 1980 Shenzhen was designated as China’s first Special Economic Zone (SEZ), resulting in large scale foreign investment, increased population and rapid economic growth.
Shenzhen’s landscape is composed of three main districts; Baoan, Longgang and Futian. Futian functions as the cities urban center, home to the government, municipal committee and CBD. It is comprised of four districts; Nanshan, Luohu, Yantian and Futian (CBD).

VILLAGE
South-east of the Futian districts civic centre, the Gangxia Urban village is a high density urban village comprised approximately 900 indigenous villagers and nearly 100,000 migrants within a 0.23km2 area. The main function of the village is providing private dwellings but has a diverse range of commercial activity within its narrow streets and laneways.

INVITE Building edge is raised at corner ends to invite pedestrians from both contextual environments. This path is encouraged through an organic landscape promenade, specifically towards the publically accessible undercroft.
TRANSITION Building height to transition from high point at streetscape to integrate with high rise typology and fall towards the urban village where the roof level is significantly lower.
BLEND Roofs are pitched and merged to create sloping fall toward the urban village, making stormwater catchment more efficient, while complimenting the sloping geometry of the undercroft.

FAÇ A D E A N ATO M Y The facade of each program is treated in opposit ion to define them respec tively and control the level of privacy re quired for their varying purposes. Referencing the anatomical digestive quality of the ADP program, their treat ment references the anatomical composition of the skeletal (str uc tural), vascular (services) and epidermis (facade) in their layering.
EXTERNAL & INTERNAL FORM The rec tilinear external form from the respec tive street interfaces is contrasted with the organic and energetic quality of the internal programming , creating a familiarity externally in its form and scale while the inter nal experience subver ts the expec tation of the viewer. This opposition is suggested by the rounding of the overhangs along the external promenade.

PUBLIC ENGAGEMENT The buildings processes are visible from st reet level through immediate vis ual connec tion as well as secondary ac tivity. The open atrium connec t ions and proximity of the public realm to the plants proccesses allow visibility into its various interac tive func t ions. This transparency aims to engage visistors along an ar chitec tural promenade as they encounter the facility.
TEXTURAL CONNECTION C onsistency of materiality along cir culation paths to create a clear and connec ted promenade that guides the viewer through b oth programs. This is maintained in the bath house through a visual connec tion to water.
ANAEROBIC DIGESTION PLANT PROCESS 1:200
T H E AT R I C A L E X P E R I E N C E The anaerobic digestion plant allows par ticipation and engagement with waste management processes in an interac tive manner. Using t his approach, the expec tation of the viewer is challenged, as the expec ted func tion is reinterpreted. This approach to the waste management process aims to ac tively encourage waste management initiatives through the experience of the facility. Fur thermore it provides education ab out sustainable waste management in conjunc tion with renewable energy pro duc tion.
M I M I C K I N G A N ATO M I C A L P R O C E S S E S The ac tive and kinetic process involved in energy pro duc tion is expressed through the treatment of par ts of the anaerobic digestion plant. Targeting children and students, these system par ts are accompanied with elements of play that allow the par ticipant t o mimic the same process as they progress through the facility, creating a didac tic experience of the anaerobic digestion plant processes.

P O R O U S & P E R F O R M AT I V E The double skin cur tain wall facade system uses the cavity space to reticulate pipework that releases steam through the perforat ed copper panel system, giving the appearance that the building is ‘sweating’, speaking to the anatomical quality of the digestive process. This performative quality of the facade system allows the bath house to purge excess steam to manage internal visibility while creating an external experience which is dynamic and ephemeral, much like the digestive process.
