Member Since: 2011

Member Offices: New York City

The partners of Polshek Partnership Architects have renamed their practice Ennead Architects LLP. This event marks the culmination of a gradual transition in organizational structure and leadership from the partnership's identification with a single design leader to its identification with a group of accomplished architects.

Ennead, which means a group of nine, authentically captures the spirit, ethnic, achievements and aspirations of the partners. The number is important only to mark the intentions of the current partners: the identity is a platform for a common trajectory and signals a new vitality.

The partnership remains an alliance of individuals, who have unique talents, ideas, experiences and skills and also share a history, a discipline, a philosophy, resources and an approach to problem solving.
