Other than necessary mechanical systems and bathrooms, the building's entire second story will be devoted to gallery space. Arranged in four broad clusters around the building, each one of the twenty-six core galleries is designed in the form of a square or a rectangle at various scales. Other services, among them the museum's education department, shop and three restaurants, will be at ground level, as will a 300-seat theater in the section of the building on the southern side of Wilshire Boulevard.
