It’s not everyday that Downtown’s Historic Core sees the possibility of ground up construction, let alone for a high-rise.  Nevertheless, veteran developer Izek Shomof intends to construct a 34-story residential building at the intersection of 4th Street and Broadway, just one block east of the Pershing Square subway station.  Dubbed “Broadway @ 4th,” the project would consist of 450 residential condominiums above approximately 7,000 square feet of ground floor retail and restaurant space.  Rising 388 feet above ground, the tower would dwarf all of its neighboring pre-war buildings.  Designed by the Spring Street-based firm of HansonLA, Broadway @ 4th would be clad in exterior materials such as terra cotta veneer, metal and cement paneling.  Due to a stipulation within the Broadway Design Overlay, the tower’s mass would be set back approximately 30 feet from the street above its 11th floor.  This requirement facilitates high-rise construction along the Broadway corridor, while still maintaining the Historic Core’s signature mid-rise street wall.  The podium structure would contain five levels of above-grade parking, with residential units screening the garage from view on its upper floors.  Residential amenities would be concentrated on the tower’s 12th floor, with offerings including a pool, recreation room, fitness center, and sauna.
