Description

Filmer Cottage is a house built in 1711 and restored in 1887 by R.W. Mylne. The building features an exposed timber frame between colourwashed plaster panels and decorative red tile hanging on the upper part. It has a steep old red tiled roof that is half-hipped at the south and is shaped around a two-storey polygonal bay window at the southwest corner. The cottage is one and a half storeys tall with two windows, a central gabled porch, and gabled dormers above three-light windows that rise above the eaves, all with half-timbered gables. A very large red brick chimney is located on the north gable, featuring several diamond chimney shafts, along with a smaller central chimney. The central entrance has a four-panel moulded door. On the south gable, there is raised plaster that reads 'SF 1711' and 'Restored 1887 RWM.'

Susan Filmer was a joint heiress to Amwell Manor, following Thomas Filmer's death in 1701. This picturesque historic house is located at the centre of the Conservation Area and is part of a group that includes the George IV Public House and The Homestead.
