URBAN CONFLICT 1 ---- Eco-balance between species
BIRD HABITAT RESEARCH
Taihu Lake, Suzhou 709hm²
2020.3-2020.4
Group work
Suzhou Taihu Lake is located on the East Asia-Australia bird migration route, where many bird species transit and roost. The design reshapes the fragmented habitat of the wetland through the construction of different bird habitats and the use of reeds, an important bird nesting plant. While providing a nature education facility, it also reduces human disturbance to the wetland, thus achieving harmony between the city and the wetland.

ALLEY RESPONSE
Suzhou, China 5.752hm²
Summer 2018
Individual work
The design is located in a historically protected residential area of Changmen community in Suzhou. By introducing the second-floor street system as a channel of internal and external contact, the design helps to mitigate the inconvenience of narrow streets and alleys, then creates more gray spaces in response to the voice of all-age residents for a variety of social leisure spaces.

Changmen Historic District
[CHANGMEN DISTRICT]
Changmen is an ancient traditional style community along the Suzhou River, dating back to the Spring and Autumn Period, leaving with the layout of Suzhou courtyard houses in the past, filled with narrow streets, dense buildings, of which green space is extremely scarce.
Public space percentage
Green area model
Distributed on the outside of the street residential area. As a larger open space, these spaces are important part for the traffic in the community.
Courtyard model
Protecting the complete form of the residential compound, the interior has a small public inner court, bearing a lot of life functions.
Street pavement model
In front of the shops, this large area is used to store different kinds of goods and being an important place for parking.
Most of the residents in the community are family residents, aged from 9 to 72, which demand various public spaces with different functions. The survey analyzes the statistics of various types of population needs

[ALLEY RESPOND]
Combine the different activities of various groups of people in the venue and try to increase the gray space throughout the block. The innovative addition of second-floor corridor gives people an access to different blocks, parks, green space and part of the courtyard of the second floor, forming a complete second-floor system of streets and alleys.

Group work
The site is located in Moji, Kitakyushu in Japan, which used to be a coastal industrial wasteland and a park in the center of the city. The design utilizes historical legacies by re-establishing the landscape of two typical urban plots and meeting the demands of various residents to reboot the city.

[SEASIDE AWAKENING]
To make use of the openness of the coastal area, we make a landscape renovation of the original railway, and reuse the remnants of city industrial containers to carry out the transformation for public activity space. The abandoned space will be turned into an art center to reinvigorate the port to attract young people.
