550 Madison Ave., built as single-tenant offices, is undergoing a repositioning as a multi-tenant Class A property

Corsair Investment Firm Leases Full Floor at Repositioned 550 Madison Ave.

Corsair Capital LP has leased 23,919 square feet at the Olayan Group’s 550 Madison Ave., a landmarked office building that is now completing a comprehensive repositioning as multi-tenant office space. The property opened in 1984 and has housed the headquarters of just two tenants: AT&T and Sony. 

Corsair is a global specialist investment firm offering which has invested $12 billion in capital across its global buyouts and infrastructure platforms since inception. It will relocate from 717 Fifth a 15-year lease. 

The Olayan Group acquired 550 Madison in 2016 and launched the repositioning project. The property has recently completed a 240,000-square-foot lease with Chubb Limited and a 72,000-square-foot headquarters lease with Hermès. 

“We are pleased to welcome Corsair to 550 Madison as we complete its transformation into one of the most dynamic and sophisticated destinations in New York City,” said Erik Horvat, managing director of real estate at Olayan America.
