Number 104 Street Grosvenor House

This is a town house, dating to circa 1780 and built as a single unit with number 102 Watergate Street. It has been converted into offices and flats. The building is constructed of Flemish bond brown brick with grey slate roofs.

The exterior consists of a semi-basement and three full storeys. The front wing has a ridge parallel to Watergate Street; the central wing, with a parallel roof, projects west towards City Walls Road; and the rear wing is L-shaped. The Watergate Street facade features replaced hopper windows to the basement, above a painted stone plinth. The first and second storeys each have two recessed 12-pane sashes, while the third storey has two recessed 6-pane sashes. All windows have painted stone sills and wedge lintels with cambered soffits. A continuous cornice matches that of number 102 Watergate Street. Eleven stone steps, with landings above the second and tenth steps, lead to an ornamental cast-iron balustraded entrance on a rendered plinth on the west side of the Watergate Street face of the central wing. The entrance itself is a door of six fielded panels within a pedimented case, with a blank wall above.

The west gable end of the front wing has two 12-pane recessed sashes to the second storey, and one 6-pane sash to the third storey, with a ridge chimney. The middle wing’s gable-end has two recessed 12-pane sashes to the first and second storeys, a 6-pane sash, and a sash without bars to the third storey. A 6-pane sash is located in the gable, above a cambered brick head to the loft. The west face of the rear wing is battered at the corners of the second and third storeys, with a recessed 16-pane sash to each storey. All west-facing windows, except for the loft window, have painted stone sills and wedge lintels. The rear of the rear wing, rendered to the first storey, includes two inserted 4-pane casements to the first storey and a recessed 12-pane sash to the second storey.

The interior was not inspected but retains original features, and a Roman altar-housing is noted in the basement.
