Work is progressing at 215 West 42nd Street, where the historic Times Square Theater is in the process of a retail conversion and expansion. Designed by Beyer Blinder Belle and developed by NYC Economic Development Corporation and Stillman Development International, the $100 million project calls for extensive interior renovations and a vertical extension that will double the structure’s height, bringing it to 138 feet tall and six stories above ground, as well as the addition of a cellar level. The property is located in the heart of Times Square between Seventh and Eighth Avenues, and will yield 52,521 square feet with 34,313 square feet designated for commercial space.
