The building consists of 32 residences ranging from one- and two-bedroom units near the base to full-floor units with large terraces higher up, crowned by a duplex penthouse. The sloped window wall is a feature of many units. All units have full-height windows in the living and dining rooms. The apartments are outfitted with sustainable materials, including bamboo floors and wall panels, palm flooring, and river-pebble bathroom tiles. BLUE also recycles unused space on top of a neighboring commercial structure as an urban garden that provides communal space for residents and guests and broad views of the Williamsburg Bridge.
