OBJECTIVE
We aim to address the density and discontinuity of residential neighborhoods in Guangming District, Shenzhen, China, while maintaining the organic cultural friction existing in old Hu-tongs and Urban Villages.
ORIGINAL EXPLORATION
Starting off, we aimed to address the impact of rapid urbanization in the context of an ideal quality of life, culture and economic opportunities in current and future development in Schenzhen,China. Our goal is to capitalize on the cultural fabric and organizational logic of the Hu-Tongs and the carrying capacity of new development. To do so we must identify developable areas which embody these qualities for implementation of a rational prototype.

PROTOTYPE OBJECTIVE
We aim to address the density and discontinuity of residential neighborhoods in Guangming District, Shenzhen, China, while maintaining the organic cultural friction existing in old Hu-tongs and Urban Villages.
Migration | Rural to Urban The migration from rural to urban spaces results in a transient population pined between the roots of old traditions and the encroachment of new urban development.

PROTOTYPE IMPLEMENTATION
Moving forward from work done on our midterm we generated an area containing numerous relationships identified through mapping and indexing filter layers. The first step to identifying an area for implementation of our prototype.
Macro Analysis on Mesh For the next step in identifying an area for implementation, we created bounding geometry based on the location of green open spaces within our final mesh.

Macro Analysis on Mesh Seeking to address the relationship between urban villages, Hu-tongs and open spaces, we identified the boundaries that contained all three of those factors.

Assessing Density Existing Conditions: EDI
Using the ratio of intensity and density divided by expansion, we’ve quantitatively assessed that metric within the macro cellular geometry.

URBAN ANALYSIS
To mediate discontinuity between urban villages and Hu-tongs the next step was to characterize the nature of block distribution and density in the urban tissue.
Typologies
Individual buildings
We’ve compiled a simplified catalog of building types currently existing in the district. Materials range from clay masonry for small residential units to in situ concrete and steel frames for high density residential and non-residential types.

Typologies Block Patterns
These are the existing typologies of the urban dwelling condition that are then populated out into the blocks of the city. It is a demonstration the context of how densely populated the existing blocks are and often become isolated and segregated fields.

PROTOTYPE DEVELOPMENT
After development of the mediation scheme at the neighborhood level we then shifted our focus to development of building and programs, which improve and maintain the organic cultural friction existing in the Hu-tongs and Urban Villages.
Test Prototypes These are the prototype failures of our process. Initially, we where attempting to create a prototype that would decrease the overall EDI ratio of the cell. This became ill relevant as the overall objective was to improve the edge condition of the Hu-Tongs and Urban Villages.

EXISTING PROGRAM
As a reflection of the existing mix-used and informal market conditions existing, we sought to recreate the organic bottom up qualities of urbanity.

FINAL CRITIQUE
Coming out of our final review, we where confident in our ending results. As we explained to the majority of the reviewers questions, we also would have liked to develop the ground level perspective of our built land forms and make it a clearer representation of the prototype. Otherwise, for the developed parts that we did complete, the reviewers where pleased with this effort.
FINAL CRITIQUE Steve Austin Everything else is ill denied what is happening between the buildings and what happens on the ground? What surrounds these transitions?
Darrin Griechen The space in between the buildings and the space could benefit from a lot of refinement. The sense in trying to create a buffer – sense of suburban culture. Would benefit from communicating better what you are doing- solar radiations, want to be convinced of this- if the sun can’t see what is exposed it won’t work as you planned.
John Abell The zone is an incubation of two contrasting types- you want to populate this zone why do you want to do this? What is the problem of the edge? What happens in the Hutongs? Otherwise we end up in a morphological districthighly formal and abstract place to be- there are much more viable options if we start to explore the form and activities. Two sides of the petri dish- and if we had to mediate this and the populate in between them- what are they doing? What activity wise and work – are those surfaces doing?
