Mott Haven Substation

Bronx, NY

Project Overview

Mott Haven electric substation located in a dense urban section of the Bronx, N.Y. was built on a very tight schedule. The four-story, 125,000-square-foot all-precast concrete structure features a combination of precast concrete structural and architectural elements that help blend the massive structure with the urban neighborhood and visually downsize its massive size. The result is a substation that presents a believable residential presence such as a classic New York City rowhouse street.
