Description

Seal House is a house dating from the early 19th century, featuring a mid-19th century front door and a late 20th century left side extension. The original structure is made of stock brick and has a hipped slate roof with end brick chimneystacks topped with octagonal chimneypots and a wide eaves cornice. It stands three storeys tall with a basement and has three windows on the front elevation. The second floor has small cambered 12-pane sash windows, the first floor has larger cambered 12-pane sashes, and the ground floor features wider cambered 16-pane sashes. The central entrance has a cambered doorcase with a fanlight and a four-panelled door from the mid-19th century.

On the rear elevation, there is a central cambered sash window with 12 panes, which lights the stairwell. An attached stock brick garden wall, approximately 8 feet high and largely renewed in the 20th century, complements a two-foot high front garden wall with 20th century black brick coping. There are also two stock brick square gatepiers about 6 feet high, topped with stone pyramidal caps, and a gate featuring Gothick tracery.

To the right side of the house is a two-storey late 20th century extension made of stock brick, which includes two casement windows on the first floor and sash windows without glazing bars on the ground floor. Inside, the house features an early 19th century central staircase with column newels, a mahogany handrail, and stick balusters. There are wooden fireplaces, many with cast iron firegrates, original moulded cornices, and a kitchen that includes a built-in wooden dresser and a stone floor.
