Description
Washington House is a house that likely dates from the late 16th century to the 17th century and was restored in the 20th century. It is constructed of squared coursed limestone and has a Collyweston slate roof. The building has an L-shaped plan and is a single storey with an attic. The main front features a six-window range of irregularly spaced 20th-century casements set under wooden lintels. To the left, there is a gabled cross wing that has a 20th-century leaded casement at the first floor with a hood mould above it. On the right side, there are two Lincolnshire dormers with leaded casements. The cross wing has ashlar gable parapets and an ashlar stack at the apex of the gable, featuring twin flues linked by an arch. There is also a central ashlar stack with a moulded cornice.
On the left elevation, there is a 17th-century two-light stone mullion window at the first floor, which has the remains of a squint to the left. The central area of the house has a 20th-century porch. Inside, the entrance hall contains a 17th-century corner fireplace with a moulded stone surround and a four-centred arch head. The staircase features a 17th-century splat balustrade. The central room has a large open fireplace with a bressumer, salt cupboards, and an 18th-century corner cupboard. The wall next to the staircase displays a close-studded timber frame that incorporates a raised cruck. The first-floor room at the top of the staircase has a 17th-century corner fireplace with a moulded stone surround and a four-centred arch head. Visible wood corbels support the roof trusses in this room. Washington House is believed to have been the manor house of the Nowyche family and was also the home of Dame Mary Washington, who was the great-grandmother of George Washington.
