Parallel systeman alternative connecting grid in urban villages of China

in 1980 China presented the open door policy, as SEZ (SPECIAL Economic Zone) in Guangdong. The result of this reform was an economic boom presented until this day. As a result of different changes of law in China, starting from the land-use reform of 1987 to to 1989 the law of transfer of land-use rights in Shenzhen, certain areas in urban perimeter were buildable land but without any obligation of following the municipality regulations or building code. These areas that are more or less the equivalent of 11 percent of expropriated land from collectives, in this moment answer to 60 percent of accommodation need of Shenzhen for new comers. They are affordable living spaces in city center that answer the need of immigrants that move from periphery to the city with the hope of better future. Most of these people are not even registered as the residents of this city, so they don’t have any right to the services provided to citizens, not even something as simple as education for their children. The result is vast areas of developments of building up to 15 floors that are two around two meters’ distance from one another, and don’t receive any service from the municipality. The area of project is situated in south part of Shenzhen, close to one of the crossing borders of Hong Kong. The main focus area is precisely the urban villages on both sides of a highway, and connected to the rest of the city by a metro station, a train station, and two bus terminals. The project studies the possibility of a 3 dimensional grid, as an alternative connection and provider of lacking services. It is created by three lines of 60 degree, thought of, after studying the morphology of urban villages and considering the fact that in most cases, on the border they follow the direction of city blocks and after 2-3 rows of buildings the orientation of the buildings does not follow any specific rule. It is a three directional grid with 60 degree angle that overlaps the area, creating a space over the urban village, serving as a connecting bridge, and when it passes over the existing buildings of over 11 floors, it becomes 3 dimensional and creates 2 to 3 floors on top of the building which is used as common indoor space for the building and on the rooftop level it creates an open space which is the element that lacks most of all in an urban village. Apart from the lack of urban services in urban village, the most important problem in these kind of developments is the lack of an adequate vertical connection. Most of buildings in U.V. are in fact without elevators and they can reach up to 15 floors.
