30, Milsom Street

30 Milsom Street is a house that has been converted into offices and a flat. It was built between 1761 and 1765, with some alterations in the 19th century and additions in the 20th century. It is possibly the work of architect Thomas Jelly. The front is made of painted limestone ashlar, while the rear features both ashlar and rubble. The building has a double pile parapeted mansard roof covered with Welsh slate, and there is a coped party wall to the right with two ashlar stacks topped with some early clay pots. At the rear, a former mews building has a Welsh slate parapeted roof and a coped party wall with an ashlar stack to the left.

The exterior consists of three storeys, an attic, a basement, and a three-window front. The first floor features three six/nine horned sash windows in splayed ovolo moulded architraves with friezes and cornices, and a central pediment above lowered stone sills. The second floor has three six/six sash windows in eared ovolo moulded architraves with stone sills and wrought iron balconettes. On the ground floor, there is a projecting 20th-century timber shopfront on the right, and on the left, a six-panel door with flush beaded and fielded panels, a cast iron ring knocker, and a single pane overlight in a moulded and recessed reveal with raised numerals reading '30'. A panel of glass bricks in the pavement allows light into the basement. The building has two single dormers with six/six horned sashes, a modillion eaves cornice, and a coped parapet. A moulded lead hopperhead and downpipe on the right is shared with No. 31 Milsom Street. The partially visible rear elevation includes a six/six sash window on the second floor, two single dormers with six/six and eight/eight horned sashes, and a long rear extension that incorporates the former mews building with a blind rear elevation. The interior has not been inspected.
