Description

Hopper's Hall is a house dating from around 1640, with some minor additions and alterations. It features a timber frame on a brick base and is rendered, topped by a steeply pitched tiled roof. The building has a large three-cell lobby entry, complete with a porch and stair wings, and stands two storeys high with attics.

The original entrance porch, located to the right of the centre, has a raised six-panelled door set within an architrave, topped by a small bracketed hood. Above the door, on the first floor, is a two-light small pane moulded flush frame casement. The porch has a hipped roof. The remaining windows on the front are six-light mullion and transom small pane moulded flush frame casements, all beneath a continuous eaves cornice.

At the rear, there is a full-height gabled stair wing behind the entrance bay, and a later 17th-century gabled wing that projects from the left or service bay. These two sections are connected by a one-storey flat-roofed addition from the 20th century. The rear also features scattered small pane flush frame casements and a two-light gabled dormer. A low gabled bakehouse addition extends from the left end of the building.

Inside, the hall retains exposed framing with close studding and tension braces, as well as ogee stop-chamfered axial bearers and a fireplace lintel. An early 18th-century open well stair showcases turned balusters and a moulded ramped handrail.
