Description
Diocesan Hall is a building constructed between 1895 and around 1902, designed by Bentley. It is made of red brick with Portland stone dressings and features a green slate roof. The hall is positioned at right angles to the roadway. The end elevation includes a thermal window, an arched parapet, and pinnacles on each side, which are flanked by half blind and half openwork oculi that resemble flying buttresses. To the right, there is a projecting entrance with a barrel roof and a carved tympanum. The auditorium has buttressed flanks with thermal windows and a carefully detailed parapet coped with Portland stone. The interior is noted to have an apse and a tunnel vault, as reported by Pevsner. The hall is part of a group that includes the Clergy House, Archbishop's House, and The Metropolitan Cathedral Church of the Most Precious Blood on Ashley Gardens.
