Gehl 

Gehl is a networked urban strategy and design consultancy, with offices in Copenhagen, New York, and San Francisco, offering expertise in the fields of architecture, urban design, landscape architecture, and city planning.

Their approach is iterative and holistic, making cities for people and the planet using life-centered data, strategy, and design. They begin by working to understand the existing life of a space before we shape the built environment. It’s these existing activities, user groups, and behavior patterns that inform future visions and designs that invite public life to flourish.
