The five-story building at 201 East 57th Street came down last year in preparation for the corner's high-end makeover, but the site's been empty ever since. It wasn't exactly in arrested development limbo, as the Post points out today, because developer Marx Realty was just waiting for a tenant before beginning construction. Still, a hole in the ground is a hole in the ground?until it's not. And the planned glassy TPG Architecture-designed building is about to start rising on the site. Part of it will be home to TD Bank. Much of the rest of the 30,814 square feet will be home to furniture and design showrooms.
