NAC/Architecture, of Spokane, is designing a proposed $30 million renovation of Patterson Hall, illustrated here, on the Eastern Washington University campus in Cheney. The project would add 32,000 square feet of floor space to the 103,200-square-foot building in one phase, and the interior would be remodeled in a second phase of work. Construction is expected to begin in 2010, if the Washington Legislature approves funding for the project.
