One Madison Avenue

New York, New York

The Tower on One Madison Avenue, formerly home of Metropolitan Life Insurance Company Headquarters, was, at 50 stories, the tallest building in the world when it was erected in 1909 and is still a prominent fixture of the New York City skyline.

As the primary design consultant for the exterior restoration of the tower, BCA oversaw the removal of decades of accumulated soiling from the exterior Tuckahoe marble and limestone masonry façades; an extensive masonry repair and replacement program of 7,000 discrete conditions; restoration of the four monumental clock faces, cast bronze numerals, and repair of the original copper-clad clock arms; and gilding the cupola with 23.75 karat Italian gold leaf. BCA designed new windows based on archival research to resemble the 1909 originals and shepherded the tower's new lighting design through the New York City Landmarks Preservation process.
