Wyvern House

Wyvern House is a house located on Kelvedon High Street, dating from the early 17th century, with extensions added in the late 17th century and early 19th century. The original building and the 17th-century extension are timber framed and plastered, while the 19th-century extension is made of painted brick and has a roof covered with handmade red plain tiles. The house has a five-bay range that runs northwest to southeast, positioned at right angles to the street, featuring an axial stack near the front and an internal stack against the right wall near the rear. There is a late 17th-century one-bay extension at the back, along with a 20th-century single-storey lean-to extension to its right. The early 19th-century extension includes a central stack and a single-storey lean-to with a corrugated iron roof at the end.

The house is two storeys high with an attic. The northwest elevation facing the street has a ground floor featuring a late 19th-century splayed bay window with sash windows arranged in a 2-4-2 light pattern. The first floor has two early 19th-century sash windows with 12 lights. The roof is hipped. The right side of the house has scattered windows, mostly 20th-century casements, and a 20th-century door set in an early 19th-century reeded doorcase with a shallow moulded canopy. The early 19th-century extension has a blocked coach door with a segmental arch made of gauged brick, a dentilled eaves course, and a parapet gable at the rear.

Inside, the house features posts ledged for chamfered binding beams with plain and lamb's tongue stops, and 20th-century bolted knees below the northwest binding beam. There is an open well stair leading from the ground to the attic, characterized by square posts, a wide moulded handrail, a moulded and pulvinated string, and turned balusters dating from around 1700. The stair also includes two 18th-century borrowed lights with diamond leading. On the first floor, there is one early 18th-century fielded two-panel pine door leading to the front room, along with four simple two-panel doors elsewhere. A rear stair from the early 19th century features an oval-section hardwood rail with double curvature at the top and plain stick balusters. The roof has clasped purlins with some panels of wattle and daub infill, and gables to the northeast. The house is adjacent to number 178, known as Bridge House.
