Mattishall Hall

House. Dating from the late 16th or early 17th century, Mattishall Hall was refurbished in the 18th and 19th centuries. The building is constructed of brick with black and red pantile roofs. Its complex plan consists of a main block connected to an early 19th-century rear block by a double-pile arrangement from the 17th century. The house is two storeys high with attics. The symmetrical facade of approximately 1700 has six bays, featuring three surviving two-light mullion and transom windows with metal casements and original spring latches. A panelled front door is positioned opposite a stack, framed by an 18th-century eared architrave. Two remaining ground floor windows, late 18th century, are in a Gothick style, with two lights, glazing bars, and ogee-arched casements. C20 windows on the first floor closely imitate these. All windows are set beneath skewback arches with raised keystones; all original except for the two above the Gothick windows (the raised keystones may be stucco additions). A moulded brick platband and a simple dentil cornice are present. The hipped roof features a pair of two-light, pedimented dormers. An off-centre axial stack is also visible.

The north facade of the main block, with four bays, shows six blocked windows and one surviving early sash window with wide glazing bars. A doorway below has a doorcase consisting of a pair of engaged Corinthian columns supporting an entablature with a pulvinated frieze. A moulded brick platband continues from the principal facade. An early 19th-century addition of two bays extends the north facade, slightly projecting forward. Four blind windows, painted to resemble sash windows with glazing bars, are recessed beneath skewback arches with raised keystones. The early 19th-century west facade has five bays of sash windows with glazing bars, set beneath skewback arches with raised keystones (the southernmost bay is an addition). A plain platband and the two southernmost windows, which rise directly from ground level, are present. An off-centre axial stack and a plain dentil cornice complete the facade.

Inside, one room from around 1700 has raised and fielded panelling and a bolection-moulded fireplace of Frosterley marble. Butt-purlin roofs and some 17th-century doors with their original ironmongery remain in the attics. An early 18th-century staircase, of unknown provenance, was installed in the 20th century.
