About Us

terrain is a landscape architecture firm based in New York City that creates award winning, ecologically integrated and socially treasured landscapes. Experience teaches us that carefully designed and conceived places have the power to positively impact the lives of individuals and communities that live, work, and play in our landscapes. terrain embraces the energy of the city and magnifies the role of nature within it, creating transformative landscape spaces.

terrain’s work is framed within an ecological context - each project, no matter its size, is part of a network of cultural and environmental connections. We actively search for opportunities to connect to and fortify local ecosystems, whether it be through the careful design of storm-water recycling systems, the thoughtful selection of materials, or the establishment of native plant communities and habitat. Equally important is the fostering of social connections and networks. Well designed landscapes have the power to bring together families, neighbors and strangers and replenish the self.

An ethos of building is integrated into our work at every stage of our design process. Our attention to craftsmanship is rooted in durability and the desire to create lasting beauty. Principal Steven Tupu has over 20 years of New York City construction experience in realizing complex, multi-disciplinary projects. With decades of collective knowledge, terrain is a valuable collaborative partner working with developers, architects, engineers, contractors and other supporting professionals. We are a firm of makers and curious individuals who together challenge assumptions of how things are designed, assembled and fabricated. Throughout our design process we continually seek smarter and more durable methods of construction. Our experience allows us to respond quickly and efficiently craft innovative and elegant design solutions within cost-effective parameters to meet demanding time-lines.

A spirit of curiosity and collaboration drives terrain’s design process. Our process is a conversation - with our clients, with users, with the site, with the larger ecological and social framework, and with our responsive network of professional collaborators. This is an active approach that is focused on enriching our communities - celebrating urban life and the natural world.
