Boston Properties received approval from the Boston Civic Design Commission to build a glass atrium outside the uniquely-shaped building at 100 Federal St., a Boston Redevelopment Authority spokesman Nick Martin confirmed. Early presentations for the glass atrium included plans for 8,500 square feet of retail space, 500 square feet of kiosk space, and an 8,990-square-foot "winter garden" at street level, according to Boston Business Journal .
