Ennead Architects

Ennead Architects LLP (/ˈenēˌad/) is a New York City-based architectural firm. Previously known as Polshek Partnership, the firm's partners renamed their practice in mid-2010.

The 175-person firm offers architecture, master planning, historic preservation and interior design services. The majority of the firm’s work is for cultural, educational, governmental, and scientific not-for-profit institutions.

The firm is presently led by twelve Partners: Timothy P. Hartung, Duncan Hazard, V. Guy Maxwell, Kevin McClurkan, Molly McGowan, Richard Olcott, Susan T. Rodriguez, Tomas Rossant, Todd Schliemann, Peter Schubert, Don Weinreich, and Thomas Wong, with the founder of the original Polshek Partnership James Polshek holding the title of Design Counsel and remaining actively involved on select projects.

The Partners established Ennead Architects International LLP in 2012, expanding the studio's geographical reach and formalizing the firm's active pursuit of opportunities to make significant architecture throughout the world. In 2014, the firm established a Shanghai office to further streamline their operations in the Asia-Pacific.

The firm’s architectural solutions are rooted in extensive research involving the analysis of context, program, public image and environmental and construction technologies. Commitment to exploring architecture’s expressive power, and a conviction that meaningful architecture must truly represent the mission and identity of an institution drive the firm’s design philosophy.

The firm is a member of the United States Green Building Council, and twenty-five percent of registered architects on staff are LEED Accredited Professionals.
