The renovation and expansion of Dia Art Foundation`s three adjacent buildings in Chelsea establishes a greater street-level public presence for Dia. The design adds new facades and extensive building systems that respect the integrity of the buildings` original spatial, structural, and material qualities. The six-story easternmost building contains a new ground floor entry, bookstore, and a flexible “talk space” for 150 people. Connected to the lobby by new openings cut into their adjoining walls, the one-story middle and western buildings provide integrated 10,000 SF of exhibition space.
