In 1979 Sheffield Phelps and his wife Patricia donated their house to the school as a performing arts center. It is currently the Middle School Music Building.

Another project included in the 1979 Master Plan was the conversion of the house beside the performing arts center into office spaces. The building became known as the Presidents’ House to recognize the contributions of past presidents of the Board of Trustees. Communications, Business, and Facilities now have offices in this building.
