The entrance is doric columned and pedimented with triglyph entablature. Its entrance includes a pedimented portico supported by six Ionic columns. Each face is pedimented with a bracketed cornice beneath interspersed with carved medallions. The chapel itself is entered through a pedimented tetrastyle portico, of a sombre Doric order. The houses have stone and brick pedimented porticos over their entranceways. Obvious bays contrasted with fronted ornate pedimented doric columns at the entrance. The balcony is located in the center of the facade, below the pedimented portico. The red-brick exterior was clad in Bath stone, and a pedimented portico added. The rear of the building is symmetrical with pedimented windows and semicircular ground-floor arches. Facade was 9 bays wide on the entrance front with pedimented breakfront. Its plaster putti above the pedimented doorcases were probably by Giovanni Battista Guelfi. The stone facade is symmetrical, with each side being organized around a central pedimented entrance. The pedimented windows are an Italianate influence here. There are flanking bays on either side to pedimented end bays. It is in polished granite, and stands on a pedimented plinth surrounded by steps.
