Dartmouth will build a new visual arts building on Lebanon Street east of the Hopkins Center according to a press release.   (See the Downtown Hanover Vision for a general idea of siting; Brewster Hall presumably will be demolished for this project.)   Studio Art and Film and Television Studies will move into the building when it is completed.   The Dartmouth reported during February 2004 that Machado and Silvetti Associates would design this building; the firm’s Matthew Oudens, project architect for an addition to the Getty Villa and the award-winning Allston Branch of the Boston Public Library (more images), is listed as the project architect.
