Terreform ONE is a 501c3 non-profit architecture and urban think tank that advances ecological design in derelict municipal areas. By formulating unsolicited feasibility studies and egalitarian designs, their mission is to illustrate speculative environmental plans for New York City and other cities worldwide. Their intention is to support community outreach and master plan solutions in underprivileged areas that do not have direct access to qualified architects and urban designers.

Ecological design or ecodesign is an approach to designing products and services that gives special consideration to the environmental impacts of a product over its entire lifecycle. Sim Van der Ryn and Stuart Cowan define it as "any form of design that minimizes environmentally destructive impacts by integrating itself with living processes." Ecological design can also be defined as the process of integrating environmental considerations into design and development with the aim of reducing environmental impacts of products through their life cycle.
