Park Avenue just got even more private equity muscle. The Carlyle Group has inked a 10-year deal for about 150,000 square feet at SL Green’s redeveloped 245 Park Avenue and picked up roughly 52,000 square feet at 200 Park Avenue, pushing its Park Avenue footprint to about 202,000 square feet and deepening its already sizable New York presence.
Legal counsel for the tenant pegs the 245 Park Avenue lease at 150,036 square feet over a 10-year term, according to Loeb & Loeb, which lists representing Carlyle Investment Management on the deal. As first reported by Commercial Observer, Carlyle also took 52,121 square feet at 200 Park Avenue. Together the two moves total 202,157 square feet on Park Avenue, and sources told the outlet the expansion is not a simple game of musical chairs: “This is pure growth for Carlyle.”
SL Green Rides a Park Avenue Hot Streak
SL Green folded the 150,036-square-foot block at 245 Park into a March 2 announcement touting 32 Manhattan leases signed in the first two months of 2026, though it identified the tenant only as “a large global investment firm.” The release also flagged an expansion by McDermott Will & Schulte at One Vanderbilt and a separate Cliffwater lease at 245 Park, underscoring a burst of landlord momentum along Park Avenue.
Rents, Floors and Perks
On the numbers, the asking rent at 245 Park was around $175 per square foot, while space at 200 Park was marketed closer to $100 per square foot, putting both in competitive territory against the city’s ultra-trophy towers. Both buildings pitch hefty amenity packages, from tenant lounges to golf and Formula One simulators, perks that brokers say help reel in large occupiers, according to Commercial Observer.
A current market listing shows the 150,036-square-foot 245 Park space as a contiguous block spanning the 23rd through 26th floors. LoopNet reviewed that listing, which describes the floors as delivered built and furnished.
What the Deal Signals
The twin transactions bulk up an already significant institutional presence in Midtown and highlight how landlords are packaging large, amenity-heavy blocks for tenants that want contiguous space rather than a patchwork of smaller floors. Carlyle reported $477 billion in assets under management as of December 31, 2025, a scale that helps explain the firm’s ability to keep expanding in the city.
Market watchers say this will be a closely watched test of whether other big tenants follow Carlyle’s lead and grab similar blocks just outside the very top of the trophy rent spectrum.
