The City in the Sky project makes use of the Greenwich Railway Tracks in London, addressing the city's high demand for housing while enhancing community connections. The design combines residential and commercial spaces in a multi-level urban structure that seeks to foster interaction and accessibility among residents.

Design Concept

The architectural layout reimagines the railway viaducts, which have primarily functioned as storage and maintenance areas, turning them into a lively mixed-use environment. Comprised of a two-story, low-rise structure, the project spans about 5 kilometers, creating a continuous living area that features streets elevated above the ground. This approach aims to connect individual living and working needs with broader community experiences.

Programmatic Elements

Mixed-use floors within the City in the Sky include both living units and community facilities such as kindergartens and workspace offices. This design provides vital services for residents and serves as a sound-insulating buffer between the apartments and active train operations below. By integrating various activities within the same space, the environment promotes a vibrant atmosphere where daily life and work can coexist.

Community Interaction

Pedestrian paths and public squares are woven throughout the design, facilitating movement and fostering social connections among residents. Circular public spaces feature restaurants and cafes, encouraging community engagement and enhancing urban life. These areas contribute to a livelier atmosphere, breaking down the usual barriers often found in city designs.

Housing Capacity

The plan can accommodate over 250,000 new homes without needing to acquire additional land, presenting a sustainable approach to urban development. By offering diverse apartment types, from affordable units to more premium residences, the project meets the varying needs of a dense population. This inclusivity is essential in addressing the ongoing housing crisis in the city.

The City in the Sky concludes with communal spaces that encourage exploration and connection, framed by an inviting streetscape that serves as a gathering point for residents.
