200 Fifth Avenue overlooks Madison Square Park in New York. Originally built in 1909, this 14-story office building underwent a facade renovation in 2015.
The renovation transformed transformed the building into a premier Class A office. Structurally a steel-framed structure with concrete floor slabs, features masonry, terracotta and stone exterior walls. A pre-stressed steel cable structural glass was implemented in the main entrance. Also, widening of the existing courtyard at the lower floors was included for creating new upper floors in the west side of this space. The lobbies are enclosed by a structurally glazed facade with terracotta louvers that overlook the courtyard, allowing the infiltration of abundant natural light. After the retrofit, the building received LEED Gold certification.
