The reliefs depict pairs of Famous Friends, including David and Jonathan, Achilles and Patroclus, Castor and Pollux, and Roland and Oliver. There are two round-arched windows on Castle Street and four windows along Brunswick Street, accompanied by another doorway, pilasters, and a pediment. The corner turret rises to a green copper onion dome. The cross windows are separated by attached fluted columns, with those on the second floor featuring statues in niches. The steep roof has dormers topped with swept copper roofs and button finials. The end bay on Brunswick Street has a shaped gable with an obelisk finial, and there are two scrolled and moulded stacks.
