Project Overview

The Plaza was designed by Architect Henry J. Hardenberg and was built between 1905-1907 in the French Renaissance style with an impressive white mass, ornamentation, and high mansard roofs. It is an outstanding example of American Hotel Architecture of the first decade of the twentieth century, and it remains closely associated with the social and cultural life of the city.

The restoration included cleaning the façades, replacing failing mortar joints, replacing deteriorated terracotta, coating and glazing deteriorated units, replacing terracotta balusters and marble bosses at the 4th floor balconettes with custom-made molds, cleaning and strengthening marble façades with a breathable stone treatment, and installing water proofing and sealant joints at skyward-facing joints and roofs. Our team also replaced cracked and spalled brick with matching glazed white brick. During the restoration work, the Fifth Avenue façade was covered with a custom printed mesh replicating the façade itself.

All restoration materials were compatible with materials and were approved by the New York City Landmarks Preservation Commission and the Landmarks Conservancy.
