Allen Haw and Barn Adjoining at East End

Allen Haw is a farmhouse with an attached barn, now functioning as a house, dating from the early 18th century and slightly altered. It is constructed from roughly coursed sandstone rubble, with the house being white-washed and topped with a stone slate roof. The building has a single-depth, two-unit plan oriented on an east-west axis, facing south, and features a staircase outshut at the rear, with the barn extending at the east end. A later lean-to at the west end is not of special interest.

The exterior consists of two storeys and two windows, arranged almost symmetrically. A stone slate drip-course runs over the ground floor, interrupted in the centre by a gabled porch. To the left, there is a large oblong fixed window with 40 small panes, featuring opening panes in the top corners. Above this is a square 20-pane fixed window with one opening pane in the top left corner, and to the right, there is a similar but smaller window on each floor, with the upper window altered to a casement but still retaining the small panes. A square extruded chimney is located at the left gable, while a ridge chimney is positioned at the junction with the barn on the right. The barn, which is a longer range situated on higher ground but continuous with the house, has a wagon doorway offset to the left of centre and an additional doorway to the left that abuts the junction with the house.

At the rear, there is an outshut that is continuous with the barn, featuring a narrow stair-window near the west end of the outshut, a small square two-light casement window to the left and below this (which serves as a pantry), and a one-light window at the first floor above. A recently-added gabled porch is attached to the added lean-to. There is a doorway to the barn that abuts the junction with the house, which has a board door, and a loading door immediately above it.

Inside, the house part to the left features a lateral beam, a large 18th-century rectangular fireplace with a corbelled lintel that includes a wide false keystone, and a narrow built-in cupboard in the opposite wall. A stone staircase is located off the rear corner, although the steps have been rebuilt.
