545 Madison Avenue

The elegant glass building at 545 Madison Avenue has two things in common with the 1955-vintage high rise that stood there for the previous 53 years — an elite address and a sturdy structural frame. Beyond that, the new 545 Madison Avenue — which was transformed from a workmanlike midtown office building into a strikingly contemporary 17-story tower and the 27th LEED Gold-rating in New York City — represents as remarkable a renovation and as thorough an overhaul as the city has seen in years. The architecture firm of Moed de Armas & Shannon supervised 545 Madison’s rebirth, and ensured that the new building rising around the built-to-last core of the original 545 Madison was up to date in every way.

A floor to ceiling glass curtain wall guarantees that each of 545 Madison’s 17 stories of class-A office space — full-floor and multi-floor options range in size from 6,200 to 9,300 square feet, with a 900 square foot penthouse also available — are bathed in natural light. An array of high-efficiency building system improvements were made across 545 Madison, with state-of-the-art HVAC, electrical and mechanical systems built seamlessly into 545 Madison’s renovation. With its mid-century foundations and next-generation sustainability, 545 Madison is a gold-standard green building that offers both a familiar address and a bright future.
