Roppongi Hills' nerve center is Mori Tower, a 54-story office building by Kohn Pedersen Fox that houses the Mori Arts Center, made up of the Mori Art Museum, a social club, a multi-purpose academic facility, and observation decks. Atypically large floor plates - approximately 120,000 s.f. each - enable the insertion of alternative uses beyond the typical office environments; the Center itself within the top four floors of the tower below the sky deck. To give the Center a presence it is divided into two components: the interior spaces within the tower and an entry structure at ground level that is the project's sole exterior expression. The conical entry pavilion, designed by New York's Gluckman Mayner Architects is a glass-clad, freestanding element with overlapping glass panes, much like the scales of a fish.
