Description

Amwellbury is a house from the 18th century that incorporates the core of an earlier timber-framed structure. A large extension built around 1800 was demolished after 1945. The house is two stories tall and features an irregular small design, constructed of red brick with a roughcast finish on the garden front (east). There is a shallower 18th-century red brick parallel range at the front, creating a double-pile plan. The roofs are old and tiled, with boxed eaves; they are hipped to the north and gabled to the south. The main range has a large gable chimney, while a smaller chimney is located in the valley between the two ranges near the north end. There are irregular small extensions from the 19th and 20th centuries to the south.

The west front, which was formerly symmetrical, has three windows with slightly recessed sash windows featuring 6/6 panes and early 19th-century blind boxes. There is a ghost of a pedimented doorcase above a blocked opening on the right. The current doorway has flanking sash windows linked under a moulded cornice with a segmental pediment on the left. An early 19th-century projecting single-storey brick bay with a hipped tiled roof and a triple-sash window is also present. Notably, there are three fine terracotta decorative chimney pots by the door, dating from around the time of the 1800 extension. Amwellbury is an historic house that is part of a picturesque group alongside Amwellbury Farmhouse and the dovecote.
