The following text is from the original listed building designation:
HADLOW HIGH STREET (north side) TQ 63 49 7/71 Walnut Tree Cottage
GV II
House. Mid/late C17 with some C19 and C20 modernisation. Timber-framed, ground floor is mostly underbuilt with white-washed C19 and C20 brick although some of the frame shows; first floor clad with peg-tile; brick stacks and chimneyshafts; peg-tile roof.
Plan: 2-room plan detached cottage set back from the street and end on to it to the south east. The larger front room has a lateral stack on the right (north eastern) side which is now behind secondary service outshots that side. Rear room was originally unheated but now has a C19 rear gable-end stack. The stairs rise alongside the lateral stack. Direct entry into the front room.
2 storeys with attics and lean-to outshots on right side.
Exterior: The windows around the house are of various sizes and are irregularly distributed. Most are C20 replacement casements with glazing bars but the attic window in the rear gable is older and contains rectangular panes of leaded glass. Front doorway behind a small C20 brick porch with low pyramid roof. Roof is gable-ended and on the right side is carried down over the outshots and interrupted by a dormer lighting the stairs.
Interior: The exposed C17 carpentry indicates that the original structure is well preserved. Both ground floor room crossbeams are chamfered with scroll stops and, on the first floor, the wallplate has the same finish. Some of the frame is exposed internally first floor rear; large framing with broad curving tension braces. The jowled wall posts indicate a 2-bay roof but the structure is plastered over in the attics.
Walnut Cottage is an interesting and well-preserved example of a small C17 house. Furthermore it forms part of a group of varied and attractive buildings in the centre of Hadlow.
