St Margarets Guest House And Wall Adjoining Approximately 30 Metres To North Of Castle

St Margaret's Guest House, along with the adjoining wall located approximately 30 metres north of Hazlewood Castle, is a building that dates from the mid to late 18th century and has undergone later alterations. It is likely the work of architect John Carr. The structure is made of dressed magnesian limestone and features a Welsh slate roof.

The guest house is two storeys high and consists of eight bays, with a central four-bay pedimented section that projects forward. It has a plinth and stable entrances located in the second and seventh bays, which are fitted with 19th-century six-fielded-panel doors that have patterned overlights and are set under flat arches. The ground floor includes 12-pane sash windows under flat arches in the outer bays and 9-pane round-arched sash windows with radial glazing in the heads of the centre bays. The first floor features four-pane sash windows with sills, also under flat arches. A projecting eaves band runs across the pediment, which is adorned with a circular sundial. The roof is hipped.

The wall to the west of the guest house has a round-arched opening leading to the stableyard, set within a larger arch that includes imposts and a cornice.
