Swiss Re is jumping from one top-floor spot in Midtown to another that includes outdoor space.

Real estate sources say the reinsurance company has just opted to lease 67,688 square feet on the 43rd through 45th floors at Paramount’s 1301 Sixth Ave.

The 45th floor is just 6,907 square feet, but has dramatic 21-foot-high ceilings and includes a huge outdoor terrace with Central Park views. The 44th floor also has oversized 16-foot-high ceilings. “The Swiss will do something special there,” said our yodeling source.

The asking rent was $100 per square foot.

The company is currently located in 93,344 square feet on the 40th to 42nd floors at the Fisher Bros.’ Park Ave. Plaza at 55 E. 52nd St., which CoStar shows as available in November 2017. BlackRock also leases 242,298 square feet there that will be given up when it moves in a few years, to 50 Hudson Yards.

Rob Martin of JLL represented Swiss Re along with brokers from Colliers International. The JLL team of Frank Doyle, David Kleiner and Clark Finney represented Paramount along with Peter Brindley in-house.

Swiss Re’s US headquarters are in Armonk and, while the jump from skyscraper to skyscraper is a bit of a downsizing, the open floor plan and terrace will likely attract the desired millennial workers.

None of the companies would comment.
