Transwestern's New York City office has represented Williams, Jones & Associates in a lease renewal and expansion at 717 Fifth Ave. in the Plaza District submarket. The expanding New York City investment management firm will increase its space in the building by moving to the 11th floor and occupying a total of 13,581 s/f. "Williams Jones has been a long-time occupant of 717 Fifth Ave.," said Lindsay Ornstein, principal at Transwestern. "When their occupancy needs changed and they required additional space, the building owner worked with us to relocate the firm within the building and accommodate their growth." "The firm has continued to grow, and we are pleased with the efforts of Transwestern and Equity Office Properties to accommodate this growth and enable us to remain in the building for a third decade," said William Jones, Jr., chairman of Williams Jones. Ornstein and Patrick Robinson of Transwestern represented Williams Jones. Zachary Freeman, Stephen Winter, Ryan Alexander, Brian Hay and Robert Stillman of CBRE represented Equity Office Properties. Built in 1958, 717 Fifth Ave. is a 468,000 s/f, class A office building. Located at the southeast corner of East 56th St. and 5th Ave., the 26-story building provides numerous amenities such as 24/7 building access, a restaurant, a new lobby with dual access and stunning views of Central Park. It is in close proximity to six major subway lines.
