Structure first: Type I concrete, seven levels above grade over a single below grade garage. That garage holds 34 stalls, fewer than the number of homes in the building. About 2,900 square feet of retail fronts the street at the ground floor, and the shared spaces run from a double height lobby floored in Portuguese limestone up to a rooftop sky lounge. The building also answers to 2465 Van Ness Avenue.
