YOO D4 is a stunning 2007 renovation of the former D4 police station of the South End. It comprises 26 units, from one- to three-bedrooms, and bears the signature of world-famous designer Philippe Starck. A new glass and steel aisle on the north side closes the formerly U-shaped courtyard to create a soaring glass-domed winter garden in the heart of the building, displaying abundant greenery. Environmentally friendly, Yoo D4 features a green roof, solar atrium space and bamboo flooring. Enjoy living in this charming corner of the South End with its historic townhouses, tree-lined streets, and lovely squares and parks.
