Thornham Hall

House. Built around 1780 for George Hogge, it exemplifies the Adam-Chambers Neo-Classical domestic style. The house is constructed of red brick in a Flemish bond pattern, with Westmoreland slate roofs. It is three stories high with attics, featuring a five-bay central block and two-story single-bay wings set on axis. The facade is executed in exceptionally fine Flemish bond brickwork.

The central block has four ground-floor sash windows with glazing bars. The central entrance features a two-leaf, three-panel raised and fielded door, topped with a fluted frieze and sheltered by a flat-roofed porch with two simple, rounded, fluted columns and two panel piers. Above the door is a large fanlight with decorated lead glazing bars set within a segmental rubbed brick arch. The first floor has four sash windows with glazing bars, the central sash set within a rubbed brick arch, itself within a recessed panel underneath a further segmental rubbed brick arch. The second floor mirrors the ground floor with four sash windows and a central tripartite Diocletian window with sash and glazing bars, also beneath a segmental rubbed brick arch. The lower level is finished with a stone plinth, while the first and second floors have white-painted stone plat bands and an attic eaves cornice. The roof has a shallow pitch with a central tripartite canted dormer projecting to the east and west, featuring sash windows with glazing bars. Wrought iron balconies are positioned above. The house has two end stacks.

The wings, slightly recessed and set on axis to the facade, are two stories high and have one arched-headed sash window with glazing bars, set within a panel under a rubbed brick arch, on the ground floor. The first floor of the wings features Diocletian windows with sash and glazing bars, all within segmental rubbed brick arches. These wings also have white-painted stone plat bands, eaves level cornices, and hipped roofs. A two-story service wing extends to the north, while a single-story internal access corridor was added to the rear around 1900.

The interior includes a plastered and panelled room on the south side, featuring a frieze of swags, urns, and dishes, as well as peltae and husks. An arched alcove on the north side contains high-quality plasterwork depicting a reclining female figure and a Bacchante filling her dish from a wineskin, all executed in the Adam-Chambers style. A contemporary white and yellow marble fireplace has fluted pilasters, a carved central panel with two opposed gryphons and an urn. A room above on the first floor contains an apse and a fireplace dating from around 1840. The central ground-floor entrance vestibule has two groin vaults and fluted doors. A two-story apsed staircase features a modillion cornice, simple rectangular wooden balusters, and a mahogany handrail with inlaid base. A room to the north has a plaster frieze of honeysuckle and urns and cornice work, with a fireplace dating from around 1860.
