Houghton Mifflin Harcourt Expanding at 3 Park Avenue to 100K SF  


Publishing giant Houghton Mifflin Harcourt has nearly tripled the size of its future headquarters at the 41-story office tower at 3 Park Avenue—before actually moving in.

The firm, which is known for series such as Curious George and The Lord of the Rings, signed a second lease amendment to expand to a total of 102,000 square feet in the Cohen Brothers Realty Corporation-owned building between East 33rd and East 34th Streets, as The Wall Street Journal first reported.

Houghton is relocating from 215 Park Avenue South between East 17th and East 18th Streets early next year. The latest addition is for 10,500 square feet, which comprises a portion of the 23rd floor, according to a Cohen Brothers news release.

The publishing firm originally signed a 12-year lease in December for just 35,000 square feet of space on part of the 18th floor and the entire 19th floor, as Commercial Observer previously reported. But then it added 55,000 square feet in June for the entire 21st and 24th floors, as well as the remaining portion of the 18th floor, bringing its total to 90,000 square feet. Asking rent for its entire space is $63 per square foot.

Cohen Brothers was represented in-house by Marc Horowitz, while David Glassman and Joseph Cabrera of Colliers International represented Houghton. Messrs. Glassman and Cabrera did not immediately return a request for comment.

Houghton will not be the only publisher in the building when it moves in. In April, high-end coffee table book publisher Assouline signed a lease for a 10,000-square-foot space on the 27th floor.

Other tenants in the tower include, Return Path and Cintra Software and Services.
