Boston's new South Station Tower will be a 51-story, 1,020,000-square-foot property. The skyline-defining tower has been thoughtfully designed by global placemaker Pelli Clarke & Partners, with interiors designed by Jeffrey Beers International and an expansive private sky park designed by OJB Landscape Architecture. 

The upper 16 floors will contain the new Ritz-Carlton residences. The 166 residential units range in size from under 1,000 square feet for studios and “junior one-bedrooms” to just under 4,000 square feet for duplex penthouses. The lowest residential floor will be 450 feet in the air. A 36th-level amenity floor will include indoor/outdoor space — including a western-facing pool and another terrace with space for outdoor cooking. The 11th floor will have the outdoor sky park. 

 Beyond the office and residential tower, the first phase of the South Station project includes an expanded bus terminal and an upgraded train concourse. There are two additional phases to come — a residential or hotel building above the bus terminal expansion, and another 510,000 square feet of office and amenity space above the existing bus terminal. The three phases together are expected to add just under 2 million square feet of new space, along with 895 parking spaces.
