Talk about an early renewal. Last year’s overall Class A office-rent bounce of about 15 percent put some spring into one tenant’s decision-making.

Random House, which had 645,000 square feet at its namesake building at 1745 Broadway expiring in June 2018, has extended the 361,0000 square feet it wants for five years to 2023.

Developed by the Related Cos. for Random House and topped by the Park Imperial residential condominiums, the building is now owned by SL Green Realty Corp., the Witkoff Group and SITQ Immobilier.

Richard Bernstein of Cassidy Turley represented the Bertelsmann-owned Random House in the lease extension for floors 2 through 13. Bernstein’s team has the 16th and 19th-22nd floors for sublease through June 2018 for $55 a square foot.

“Leases are completed on 17, 18, 24 and 25, and we have a lease going out on three more floors,” said Bernstein.

Steve Durels negotiated in-house for SLG and said the lease that starts in 2018 was at a “very full” rent. Indeed, trying to project a Class A rent six years from now is for fortunetellers.

“They clearly understood that the market was moving and that rents over the medium term would rise significantly,” said Durels.
