Leave it as is (maybe add more trees around the perimeter). It serves as bicycle parking during festival season and we need to leave at least some parking for tourists and Place des Arts patrons. The view in all directions will be much more interesting: Louis Boehme, Ilot Balmoral, U of Mtl, Place des Arts, Peterson, Le Devoir offices and even Domtar park are better viewed from a distance (to appreciate their lines and forms). All of these views would be lost behind a possibly banal building that would turn de Maisonneuve into a cavern of buildings, perpetually in shadow. Besides, Domtar could always decide to close the "park" and build there, just another brick in the wall.
