No.1 and Attached Railings and Vaults

This is a terrace house, built around 1770 to 1776, with alterations in the 19th and 20th centuries. The front is faced with limestone ashlar, painted on the ground floor and basement, while the rear is a mix of rubble and ashlar. The roof is a mansard style with Welsh slate to the front and artificial slate to the rear, and features two ashlar chimney stacks with early clay pots rising above a coped party wall on the right side. A staircase is located at the rear.

The house has three storeys, an attic, and a basement, with a three-window front. The first floor features a Venetian window with plate glass, horned sashes and splayed reveals. A lowered stone sill supports a large wrought iron balconette, held by scrolled wrought iron brackets. Above this, the second floor has three grouped windows with four/four, six/six, and four/four sashes in splayed reveals and a continuous stone sill. The ground floor has paired two/two sashes on the left, and a six-panel door with flush and glazed panels within a stone doorcase featuring an ovolo moulded architrave, frieze and moulded cornice. A single step leads to a pennant paved crossover with a 19th-century cast iron footscraper. The basement has two two/two horned sashes in plain reveals and a blocked doorway under the crossover, along with a two-light casement window to the vaults and 20th-century area steps. A double dormer with plate glass sashes is present in the roof.

A continuous band course runs above the ground floor, while a sill band is present on the first floor. A bracketed eaves cornice and coped parapet tie the building in with numbers 2, 3, and 4 Montpelier. The partially visible rear elevation shows an inserted WC window on a half-level, above the second floor, with a rebuilt wall in ashlar, raised above the parapet, and a window inserted into the roof. The interior has not been inspected.

Attached wrought iron railings and a gate, with shaped heads on limestone bases, are present. Attached vaults include a raised pennant pavement with a simple wrought iron railing along the front edge, with two small openings—one with a plank door and one blocked—leading to the roadway. The group value of this building lies in its contribution to the historic character and appearance of the Montpelier terrace.
