This project is a food supply system design in Bronx, New York. The focused are is along the 3rd Ave near the NYCHA housing, which the residents are in proverty. Due to the food culture and low income, people in this area prefer to buy fast food, which is unhealthy and cause high rate of obesity. So, the goal of this project is to create a food system in the Bronx and provide people with more convenience and more accessible ways to get fresh food, and offer them several choices, which will include the Bodega, Fresh Truck, and also Community Garden. And we will try to incorporate with the government and other organizations to work together, which include the Hunts Points distribution, NYC Sanitation Department, Grow NYC, Mayor’s Office, and Community Associations.

The American suburban shopping mall is the “property” built for the consumption and living habits of the American middle class. The design and operation of the shopping mall philosophy is creating the maximum possible economic benefit in the shortest time. However, with change of people’s lifestyles and emerge of online shopping in 21 century, the traditional shopping mall has gone into decline.
This project illustrates how the space of greenbriar mall can be intervened and absorbed by the activities of youth, but it was never to discontinue the existing relationship between the community and the greenbriar mall. The project rather to facilitate the idea that youth communication and learning should not be tied to traditional classrooms and outside of the social framework and community life. The process should be more expansive and dynamic, subtlety affecting young people of all ages in different spaces that is not clearly defined. Only better to accommodate youth population will make community sustainable.

Although the Greenbriar mall is dying as a commercial space, it used to attract a group of people who were forgotten or even rejected by malls, those who did not have the ability to spend but were active in every corner of the shopping mall spaces: teenagers and youths, Shopping malls are one of the few safe recreational spaces in suburban communities for them who live far from thriving urban areas.

Breakdown the Property
Project Statement
The topic of this project is to breakdown the property. However, the “dead” mall itself was once synonymous with capital that most shopping malls from the last century to the present still believe that the activities of young people in the mall are reducing the revenue that the mall can generate. So, the proposal of this project is to claim that all malls in the United States should encourage and support the social learning and leisure activities of youth. Especially for communities that lack safe public spaces for youth activities.
The main idea of the design is to breakdown the mall by adding a large corridor structure in the center of the mall in order to provide more activities for the neighborhood. The corridor will provide multiple spaces for young people that they can define the function of spaces by theirselves according to the use. By infusing new and dynamic programs, the dead mall has been transformed into a place for young people to learn, play, and socialize. The traditional sense of a mall built for capital interests will be transformed into a youth paradise.

Reclaiming The “Sabana”

The Fucha River, a tributary of the Bogotá and Magdalena Rivers that crosses the city of Bogotá, has a river ecosystem and water quality that affects the water system of the eastern Andes and even the whole of Colombia. However, the Fucha River is considered one of the most polluted rivers in the world, with 90% of the pollution coming from within the Bogotá metropolitan area, so it is urgent to rehabilitate the Fucha River and the surrounding area.
This project proposed the Fucha river as a new holding system to connect the canals, wetlands, and rivers and finally to reclaim the “Sabana” plain. The water bodies will be reconnected into a new urban ecology system to be more stable and robust.

14
The main concept of this project is to extend the river bank and transform the concrete canal into natural landscape with softening materials and improved green infrastructure. And most importantly, bring this environment into the urban fabric and be accessible to local people.
Due to the difference of the types of pollutants, there will be three strategies to deal with different conditions. In order to create a robust and stable urban ecology at the waterfront, this project shifts the market-based planning to river-based planning, an ecological and sustainable way of moving forward.
15
Interconnection between functions and zones
The program is divided into four steps including reclaimed land, Reshape river, Rebuild wetland, and Re-mixed region function.While providing new riverside commercial space, the new zoning plan also provides affordable housing to compensate residents whose housing are exchanged for commercial space
16
Mixed-use redevelopment
This phase is to add biological water purification structures. The concrete river bank will be broken up and widened. Additionally, the bio thermalsnd filtration pond along the sewage systems will be added in order to deal with the polluted water from the heavey industry areas that along the Fucha River.
17
Recovery of wetland and nature
The main goal of this phase is to restore the natural environment of the site so that the green infrastructure could gradually permeate the surrounding community, which could provide people a more healthy and natural neighborhood to live in. The strategies used in this phase is providing more wetlands for the river water to be precipitaed and aquatic nurseries to cultivate plant that could be used in natural purification system. Besides, the design of community garden and the aquatic nursery could also engage with the neighborhoods.

BELOW THE TRACK

Site: Hazelwood, Pittsburgh, 2020.3
Type: Academic
Course Number: Larch 414 V
This project is a functional design for the residents who live in the Hazlewood community. The function includes the community garden, farmer's market, public plaza, amphitheater, and restaurant. The aim of this project is providing food sources and job opportunities for the community, improving the living quality in Hazelwood, Pittsburgh. The site used to be a large trail transition for the goods, while part of the trail line has been abandoned for years, making the site become isolated from the community and also block the way to the Monongahela River. In this project, I made carefully pre-studies and fild trip to identify the main problems that residents concerned about and the kind of community that they wish to live in. Consequently, the BELOW THE TRACK idea is brought out.

garden that has been used for more than fifty years, and a recreation area that is in the construction. People from the community is isolated from the river because of the railroad, which has been abandoned. So, it is suitable for the construction of the focused area to provide opportunities for people to get close to the river and a recreation space for tourists and residents.
People from the community are separated from the river by walls and trail.
There is no market arround the community, which is inconvenient for residents to get food.
The employmentrate is extremely low in the community.Alot of families are poverty and there are few job opportunities.

Type: Academic
Course Number: PLANA4578
This project is to provide a eco-friendly and safe corridor for terrestrial animals to migrate. In the Spring Creek Watershed, most animals are living in the Nittany Mountain and Rothrock State Forest, while several highway and trails are in between. During the four-year living in State College, I noticed a lot of deers or some small animals died as a result of car accidents. Before the design, I did a lot of researches and using the GIS to culculate the best migration way for the animals to move. The design is for the areas
where the corridor crashed with highway and trail.
