“KITCHEN AWAY FROM HOME”
Urban Villages: Home for Migrant Workers
Reimagine Public Realm in Urban Villages for An Inclusive City Year: 2019 Spring
This research and design proposal for Shenzhen Urban Planning & Design Institute investigates in the city’s growth and the formation of the urban villages. Proactive Design Objectives and Implementation Strategies are developed based on the demand of various stakeholders and the complexity of village ownerships and urban forms. The proposed public realms and community programs serve to connect the informal and the formal, the residents and the migrants, and the village and the city.

Earl’s Court People’s Master Plan (No Demolition)
Depot for London Underground Exhibition Centre under Demolition
Year: 2017 Spring West Ken & Gibbs Green Community
Location: London, UK The Earl’s Court site (28 hectare), located at the prime real estate area in London, is subject to a contentious mixeduse redevelopment plan, with extensive demolition of the existing house estates and relocation of residents on site. Our team worked as urban design consultants to the West Ken & Gibbs Green Community and its residents, to develop the People’s Masterplan, which offers an alternative framework with urban intensification and encourage interactions at public space.

Step 7: linear improvement along street shoud also be considered: use Calculate Geometry > Length to get the length of streets. <---<--In partucular, streets like Pearl Street, with the length of 1243, more than 1km, but connecting the main commercial corridor to riverfront, should improve its physical environment for better walking experience. <------
2. London Growth and Transit Accessibility Year: 2016 Spring Location: London, UK This research focuses on the correlation between the Public Transport Accessibility Level (PTAL) and the population density at ward level. It assesses the new dwelling development around transport hubs under the London Plan.

This project employs geospatial machine learning in the land use modeling process to support smart growth. Considerable amount of vector and raster data is collected from USGS, Census and open data websites, and wrangled together into a model-ready dataset using ArcGIS & RStudio. A Binary Logistic Regression Model is constructed and trained based on the change in development from 20012011. After cross validation, the model predicts the probability of development for 2020. The development demand is then compared with the environmental sensibility to develop a Growth Allocation procedure.
