The Lyric Apartments project is new construction of a 14-floor, 270,000 gross square foot, Class A residential apartment building located in DC’s growing Mount Vernon Triangle district. The project contains 182 one-bedroom units, 26 one-bedroom and den units, and 26 two-bedroom units for a total of 234 market rate units in 12 different unit types compromising approximately 184,000 apartment-rentable square feet.
In addition to the 234 units, the building at 440 K Street contains numerous on-site amenities. These on-site amenities include two rooftop terraces, a rooftop pool and deck, pool locker rooms, indoor and outdoor recreation space, hardscape and landscape features, fitness center, bicycle storage, individual tenant storage, a 24/7 secure residential lobby, and on-site management and leasing staff.
The project also contains approximately 9,450 gross square feet of retail space with the ability to accommodate a full-service restaurant and approximately 39,000 square feet of structured parking on two levels below grade with 96 parking spaces, as well as ten surface-parking spaces. The building will be serviced by three elevators, which access all parking and residential levels, of which, one elevator accesses the rooftop amenity and penthouse areas and can serve as a freight elevator.
The building was constructed on a 36-inch thick mat slab foundation due to poor soils and the anticipated need for substantial undercutting to reach suitable bearing capacity. The below grade parking decks and Ground Floor slab utilize traditional reinforcing, and the elevated decks utilize post-tensioned cables with mild steel reinforcing. Columns are sloped at the Ground Floor and in the parking decks to maximize unit layouts in the apartment floors. A transfer beam on the second floor was designed to carry a column from the upper floors and transfer to the parking deck columns so avoid interfering with the drive aisle. The transfer beam was constructed of two W36x260 beams 25-foot-long stitch welded together and encapsulated in a concrete casing with all rebar welded to the beam to accomplish the transfer.
The skin consists of a combination of rain screen metal panels, rain screen porcelain tile, and hardie-board on exterior sheathing and waterproofing. Operable sliding and hopper windows, terrace doors, and sliding doors with Juliet balconies make up the remainder of the building envelope. The metal panels consist of three colors; white, gray and most remarkably an iridescent color called Dragonfly which mimics the colors of its namesake’s wings.
