The East Building designed by David Chipperfield introduces a new dimension by creating a kind of abstract pedestal in the historic building. The sculpture garden extends this pedestal and introduces an intermediate scale between the museum and the vast landscape. While approaching the building, this plant massing is gradually ordered into geometrical blocks to form regular outdoor rooms that extend the museum architecture of the nineteenth century to the outside. Trees are selected for their ability to yeld a strong forested character and to be geometrically laid out. There are hundreds of hornbeams, river birches, white birches, and some serviceberries laid out in dense orthogonal grids that extend the building structure.This is a forest sculpted into a set of outdoor rooms where pieces of art are installed. These rooms are not enclosed. They appear continuously one after the other in a game of masses and voids, orchestrating a set of concrete pedestals. Naturally, they are also pedestals for sculptures.
