Sustainable design

We promote building design that minimises the impact of development on the environment. Look at the case studies of recent sustainably-designed buildings and examples of green roofs and green walls.

Design guidance

We provide advice to developers and applicants on aspects of building design.

Trees and open spaces

Although the City is densely built up, we work to increase the amount of open space and the number of trees in the Square Mile.

Flood risk

We work to ensure that the City continues to be at low risk of flooding.
