Environmental documents published yesterday by the Los Angeles Department of City Planning offer a first glimpse of 6200 Sunset Boulevard, the latest installment in Hollywood’s mixed-use development boom. The residential-retail complex, which is being developed by the Houston-based Hanover Company, would consist of a seven-story building featuring 270 studio, one- and two-bedroom units above approximately 12,400 square feet of neighborhood-serving retail and restaurant space. Plans call for a litany of on-site amenities which includes a 361-vehicle parking garage, a swimming pool, a fitness center and two roof decks. The project would rise from a 1.2-acre property at the southwest corner of Sunset Boulevard and El Centro Avenue, replacing a nondescript retail center. Designs for the low-rise building are being crafted by Steinberg Architects, a multidisciplinary firm with a portfolio that includes numerous urban infill developments. Renderings included with the project’s initial study portray a modern design featuring a three-story retail plaza along Sunset Boulevard The building’s seven-story height would provide a transition from the high-rise towers on the north side of Sunset Boulevard to the low-rise residential neighborhood to the south. As currently proposed, 6200 Sunset will require several discretionary approvals from the City of Los Angeles, including a height district change and a site plan review. Completion of the project is not expected until 2021. A similar low-rise complex is also planned a short distance west, on a surface parking lot which abuts the historic Earl Carroll Theatre.
