About 540 Leavenworth Right at home in Downtown’s lively cultural cocktail, the Element Apartments at 540 Leavenworth is a commuter’s dream. Built in 1914, this five-story Edwardian has been fully and thoughtfully remodeled to include modern and industrial design elements. Within the 100-year-old historic building these details include a minimally playful exterior paint scheme, a tech-focused entry system that enables residents to talk with and see their guests on their smartphones, and a periodic table-inspired design of the foyer. Sleeping in just became a possibility in this central location- just a short walk to Union Square, the FiDi District and Powell Street BART.
