Description

Crockham House is a timber-framed house, likely dating from the 15th century or earlier, that has been restored and altered over time, with significant additions from the 17th century and more recent periods. The front elevation is two storeys and has an attic, with three windows in the original section. It has a tiled roof with a tall, central chimney stack featuring two diagonal shafts, likely dating from the mid-17th century, and a modern, hipped dormer. A single-storey, gabled addition extends from the right front, and a modern, gabled wooden porch is present. Some original iron casements remain, while others have been replaced. There is a three-window left extension, modern but matching the style. Exposed timber framing is visible, with the infill being a mix of plaster and brick. A quarry-tiled terrace is set in front, bordered by a low stone wall.

The rear elevation has two storeys and an attic, with a variety of windows, mostly modern leaded casements. A projecting, mid-17th century timber-framed wing is situated on the right. The upper floor of this wing has plaster infill, while the lower section is built of rubble masonry with flint galleting. The end wall of this wing is of coursed rubble with flint. A stone-coped gable, topped by a brick chimney shaft bearing a datestone of 1658, features kneelers with ball finials and two diagonal shafts above.

The interior reveals substantial exposed timberwork, including very heavy arch-braced tie beams and crown posts (one brace missing). An inglenook fireplace is present, with a heavy, roll-moulded beam. Old wainscoting adorns the staircase, and there is 17th-century panelling, including an arcaded section over a chimneypiece of an upstairs room. Old plank floors remain. A section of late 16th-century wall painting is visible on the plaster, consisting of a panel with a scripture text in gothic lettering within a guilloche border, surrounded by panels of fruit and flower ornament.
