Fashioned in the Cotswold style, the cottage-like appearance of the Power House conceals its utilitarian purpose of providing power and heat. The main house and Power House are today still heated by two of the original boilers installed in 1927. A third boiler was used to heat the pool, but has not been used since Mrs. Ford's death in 1976. The Power House is connected to the main house by a 160-foot underground tunnel.
