It was built in 1934–1935 and is a large, two story "T" shaped brick and case stone building with Tudor and Jacobean Revival style features. The main seven bay block has a steeply pitched, slate-covered hipped roof and is flanked by two bay wings. It was listed on the National Register of Historic Places in 1988.
