Description

Tetworth is a house dating from the early 18th century, with an extension added in the late 18th century and alterations made in the 19th and mid-20th centuries. Originally built of brick, it is now covered in painted render and has a low pitched slate roof that is hidden behind a parapet. The building was formerly nearly square in plan, but a wing was added to the west in the late 18th century.

The house is currently two storeys and a basement, as the second floor was removed in the mid-20th century, and the chimneys have been taken down. It features sash windows with glazing bars. On the south (garden) front, the original part of the house is on the right and consists of seven bays, with three windows in each of two semicircular full-height bays and one window in the centre. The ground floor has tripartite windows in each bay, with the left bay featuring casement doors. The extension to the left has a full-height canted bay with three windows and a tripartite sash window in the centre on the ground floor.

A flight of five stone steps leads down to the garden, which is flanked by low rendered walls and piers topped with urns. The entrance door, which has six fielded panels, is now located on the west front and is approached by another flight of five stone steps. It features a Doric doorcase with a triglyph frieze and a renewed dentil cornice. Inside, the windows still have their shutters, and some rooms boast late 18th-century enriched ceiling cornices.
