Terrain Work is an international landscape architecture, urban design, and public art studio in New York City that is known for its creativity and design innovation. Terrain Work’s landscapes and urban strategies consider how landscape’s innate ability to change create new emergent forms and experiences that synthesize culture, nature, and the built environment. We approach each project with a curiosity and collaborative spirit born out of the belief that landscapes should perform as both cultural provocateur and ecological system.
