One City

A natural history of urban ecosystems

SP-001Infrastructure

Transit Networks

Like the circulatory system of a living organism, a city's transit network distributes energy and resources to every district. The health of this network determines the vitality of the whole.

SP-002Ecology

Green Corridors

Parks, gardens, and tree-lined avenues form the respiratory system of urban life. These corridors filter air, moderate temperature, and provide habitat for the countless species that share our cities.

SP-003Social

Community Nodes

Markets, cafes, libraries, and public squares — the gathering points where social bonds are formed and maintained. These nodes are where the city becomes more than infrastructure.

SP-004Resilience

Adaptive Systems

Cities that survive centuries share a common trait: the ability to adapt. Flood defenses, earthquake-resistant construction, and decentralized power grids are the immune system of urban civilization.
