A $15 million, six-story housing annex with 80 guest rooms, was completed in 2010. Designed by architect Peter Rose, the annex incorporates sustainable design elements and won a 2010 award for specialized housing from the American Institute of Architects. The institute commented on the building's interior natural lighting, and noted that the architectural design and climate control systems are integrated and consume 40 percent less energy than a conventional building. Rose also developed a master plan for increasing the center's capacity and developing it into "a model of environmental responsibility" through improvements to existing buildings, landscaping, and new construction.
