George Comfort & Sons is in “active negotiations” for 1.5 million feet of potential leases to fill the 700,000-foot hole at the bottom of Worldwide Plaza at Eighth Avenue and 50th Street.

Comfort’s Peter Duncan said since they bought the building, they have had “tours and interest from over 2 million square feet of tenants.”

Speaking at the Young Mens’/Womens’ Real Estate Association luncheon yesterday, Duncan revealed some insights into the transaction, which involved buying the former Macklowe building with partners RCG Longview and DRA Advisors and obtaining a straight mortgage from the foreclosing lender, Deutsche Bank.

“It was a tough deal to put together and the deal was pulled from us for a couple of weeks,” he said. “The results to date have been beyond our expectations.”

The available 700,000 feet — which has “tremendous light and air” — was vacated by Ogilvy & Mather in July. The asking rent for the space, which spans the 4th through 17th floors and comes with some concourse area, runs from $52 to $59 a foot, making it competitive with many Class A buildings. The most interest has come from Third Avenue tenants, Duncan said.

The morning after the closing, Duncan recalled walking the plaza area when he spotted one of the security guards with a dog. “It’s nice you brought your dog to work with you,” he told the guard, who replied with respect: “No sir, it’s your dog.”
