CB Richard Ellis represented Viacom International Inc. in its 1.35 million s/f global headquarters lease extension at 1515 Broadway. The Times Sq. tower is owned by SL Green Realty Corp. and SITQ. "The renewal allows Viacom to keep its vast employee base together in a prime building in the heart of Times Square," said Michael Laginestra, vice chairman, CBRE, who arranged the lease with Scott Gottlieb, vice chairman, and Andrew Sussman, senior VP. "Viacom is pleased to continue their longstanding relationship with SL Green." The positive outcome was a long time in the making. Laginestra said that this was a very challenging deal to put together, with many rounds of negotiation. Also known as One Astor Plaza, the 53-story, 2 million s/f property is located between 44th and 45th Sts., and fronted by Viacom's MTV studio. Viacom is the parent of Paramount, MTV Networks and BET, among other prominent entertainment properties. Marc Holliday, CEO, Steve Durels, Neil Kessner and Kathy Crocco, of SL Green, represented the landlord internally.
