13, St Johns Street

No 13 on St John's Street is an early 19th-century building made of Bath stone and features two storeys. It has a plinth, a plain frieze, a moulded cornice, and a blocking course, all topped by a low-pitched hipped slate roof. The first floor has a central tripartite sash window with intact glazing bars, flanked by pilasters that break through the sill and sit within a slight rectangular recess.

On the ground floor, there is a central portico supported by two fluted Greek Doric columns, with pilasters on the wall that carry an entablature featuring a triglyph frieze. The entablature continues across the front, framed by flanking pilasters, and it surrounds a pair of large marginal glazed windows with moulded sills, panels underneath, and double doors in the centre, also marginal glazed with flush bottom panels.

This building was formerly the workshop and office of Osmond, the mason employed by Augustus Welby Northmore Pugin. Nos 1 to 13 on St John's Street form a very important group.
