IDEAL LOCATION: Having outgrown its SoHo offices in New York, the five-year-old Ideeli will relocate to two Midtown locations this fall. The flash-sale site has secured 23,500 square feet — the entire third floor — at 1385 Broadway, a 23-story Cushman & Wakefield building. That location will be used for a photo studio and creative space for about 50 staffers. Ideeli is said to be nearing a deal at another address not far from Times Square for a sleek home office for its other 200-plus employees. By moving day, Ideeli expects to have a head count of as much as 300. The Midtown base camp will be the fourth move for Ideeli’s chief executive officer Paul Hurley, who started the company in his apartment. When the company first settled into its current offices at 148 Lafayette Street in 2009, there were 40 staffers.
