Silverstein Properties is parting ways with a piece of the former ABC campus on Manhattan’s Upper West Side after acquiring it four years ago.

Gary Barnett’s Extell Development is under contract to pay between $925M and $930M for the office properties on Columbus Avenue between West 66th and 67th streets, Commercial Observer reported, citing unnamed sources. Barnett has reportedly put down a $50M deposit — an Extell spokesperson told CO "you should check your facts" — and the deal is set to close next month.

Silverstein paid The Walt Disney Co. $1.2B for the nine-building campus back in 2018. The properties included 125 West End Ave., 320 West 66th St., 147 and 149 Columbus Ave., a parking lot on West 64th St, 77 West 66th St., 47 West 66th St., 7 West 66th St. and 30 West 67th St. Silverstein scored a $900M loan from Deutsche Bank for the purchase.

In 2019, Nuveen and Taconic partnered and paid Silverstein Properties $230M for 125 West End Ave., 320 West 66th St. and an adjacent, unbuilt site.

The joint venture has begun redeveloping 125 West End Ave. into a 400K SF life sciences building, with a new mechanical plant and purpose-built lab infrastructure, a roof terrace, a new facade and a conference center. It secured a $600M financing package earlier this year with a construction stake from Apollo Global Management and Oaktree Management and a large equity stake from LaSalle Investment Partners, CO reported.

Silverstein, most famous for building Seven, Three and Four World Trade Center, owns the remaining ABC/Disney buildings with Seven Valleys, the U.S. family office of Chinese Investor Zhang Xin and Pan Shiyi, according to CO, though the size of its stake is not clear. Eastdil Secured’s Gary Phillips and Will Silverman arranged the transaction.
