This compact complex of buildings linked by a series of arcades and academic quads in the English tradition was created to house one of Berkeley’s earliest seminaries. Hobart Hall, designed by Julia Morgan, is notable for its elaborate brickwork, elegant arched north entry, and molded terra cotta decorative detail. In 1953, architect Walter H. Ratcliff, Jr. continued the Tudor Revival style with Johnson Hall to the east and the small chapel with a double-gabled roof entry to the south. Additional campus buildings after 1964 reflect more modern architectural styles. Hobart Hall was substantially remodeled in 2000.

Zaytuna College rented space in the building for its first two years of operation, 2010–2012. In 2020, the American Baptist Seminary of the West changed its name to Berkeley School of Theology, while remaining a Baptist institution. It is affiliated with the Graduate Theological Union.
