The Museum of Fine Arts Houston’s board has selected three architecture firms to propose plans for a post-1900 art building. Morphosis, Snøhetta and Steven Holl Architects will submit concepts for the proposed building and parking garage (hey, let’s show contemporary sculpture IN the parking garage!), to be sited on the current parking lot across the street from the MFAH’s Law building and next door to the Cullen Sculpture Garden.
