Number 11 and Attached Walls

Number 11 and attached walls is a town house, now serving as a Church of England Retreat House. It was likely constructed around 1760, slightly later than numbers 7-10 on Abbey Square. The building was developed on a lease, probably lasting 40 years, from the Dean and Chapter of Chester Cathedral. It is built of Flemish bond orange brick with a grey slate roof.

The exterior presents three storeys and a cellar. A painted stone plinth is present, along with a boot-scraper accessed by four stone apron steps leading to the front door. The door itself is of four fielded panels, above a large panel incised with a St Andrew's cross, set within a case of painted stone. It is framed by an eared architrave flanked by panelled pilasters carrying a pediment on acanthus consoles. An inscription reading "PAX HUIC DOMUI; SIT PAX INTROEUNTI; SIT IN HAC HABITANTI; SIT ET EUNTI PAX" is painted on the frieze, and the Diocesan arms are displayed on the pediment, dated 1925. A boarded door provides access to the basement, located on the east side, beneath a rusticated wedge lintel with a false keystone. A sillband runs across the first storey, while rusticated quoins mark the east corner. The first storey features two recessed 12-pane sashes west of the door, with a single sash positioned between the entrance and the basement door. The second storey contains two tripartite sashes with a 4;12;4 pane configuration. The third storey has three recessed 6-pane sashes in square openings. Painted stone sillbands are present on the first and second storeys, while the third storey features painted stone sills; all windows have plain wedge lintels. A painted stone cornice sits beneath a brick parapet topped with plain stone coping. The rear elevation incorporates a semicircular bow with three recessed sashes per storey, all unequal in size, with 15 panes to the first and second storeys and 9 panes to the third. Painted stone sillbands are present on the second and third storeys, with plain wedge lintels above the windows, culminating in a hipped roof.

The interior remains largely intact, although a full inspection was not possible. The hall features a panelled embrasure with shutters. A Chinese-style open-well stair with an open string displays intricate 'Chinese Chippendale' balustrade, shaped brackets, a curtail step with a rose detail, a swept rail, bolection panels to the stairwell (likely plaster), and a domed lantern.

A damaged rear garden wall is constructed of coursed sandstone.
