Description

Rockhaven is a group of three houses located on Main Road in Dovercourt, dating from the late 16th century and later. The buildings are timber-framed and plastered, featuring two gabled roofs covered with clay plain tiles, some of which are machine-made. The houses are part two-storey and part one-storey with attics.

On the exterior, No.703 has a gabled dormer with a two-light 20th-century casement window, while No.701 features a three-light flat-roofed 20th-century dormer. There is a large chimney stack running along the ridgeline of No.703 and a smaller rendered stack on the east gable of Rockhaven, which also includes a single-storey porch extension with a lean-to roof. The windows are a mix of 19th and 20th-century casements, with No.699 having small panes and top vents. There are substantial 20th-century extensions at the rear.

Inside, No.703 contains a 17th-century inglenook fireplace with a chamfered mantel beam, a large flat chamfered bridging joist with plain stops, and flat section joists likely from the late 16th century. No.701 features a large jowled post in the rear wall of the ground floor.
