No. 11 And Attached Railings

No. 11 Catharine Place, originally a house and now flats, was constructed around 1777, with later alterations in the late 19th century and 20th century. It was designed by John the Younger. The front of the building is faced with limestone ashlar, while the rear is a combination of ashlar, rubble, and rendered walls. The double-pile, parapeted roof is mansard and covered with artificial slate at the rear. The front elevation has been altered to incorporate a slate-hung front and a flat roof terrace, which is hidden behind the parapet. A coped party wall is on the left, with two ashlar stacks featuring some early clay pots.

The house is four storeys high, with an attic and basement, and has a three-window front. The first floor has three plate glass sash windows with splayed, ovolo moulded architraves, friezes, cornices, and lowered moulded stone sills on console brackets. The second floor has three similar windows in ovolo moulded architraves with stone sills. The third floor has two similar windows in plain reveals with stone sills. The ground floor features two plate glass sash windows in plain reveals with stone sills to the left, and a six-panel door with a single glazed upper panel, set within an altered stone doorcase. The doorcase displays a cut-down cyma moulded architrave with a moulded cornice on console brackets to form a hood. A pennant paved crossover is flush with the pavement, alongside a small three-pane window in a plain reveal with a stone sill. The basement has two six/six sash windows in plain reveals with stone sills, a door with flush panels and a two-pane overlight in ashlar infilling, and no area steps. A band course runs above the ground floor and a small hollow moulded cornice sits at eaves. A coped parapet tops the building.

The rear elevation includes plate glass sash windows and 20th-century windows in dormers. An inspection by Bath Council in 1974 revealed a finely detailed cast iron fire surround on the second floor and a marble surround on another. The first floor has fine ceilings and double connecting doors.

Attached wrought iron railings and a gate are set on painted limestone bases.
