7 Hazleton

7 Hazleton is a detached cottage dating from the 17th and 19th centuries. The building is constructed from coursed and squared stone rubble with limestone quoins to the earlier bay, stone slate tiles to the main range, and concrete tiles to the rear extension. The stack is of modern brick. The plan consists of a two-room, single-depth main range with a central chimney breast, and a single-roomed rear wing to the west.

The western bay, representing the original 17th-century building, was later extended with a bay to the east in the 19th century, and a gabled rear wing was added at the same period. The main range is of one and a half stories and two bays. The main elevation features a late 19th- or early 20th-century plank door, leading into the earlier bay, and a three-light, double-chamfered stone-mullioned casement window under a stopped hood mould. Above this is a two-light stone-mullioned casement within a full gabled dormer. The bay to the right has matching 19th-century two-light stone-mullioned windows to the ground floor and a full gabled dormer. A second, half-glazed entrance door is set within a 20th-century reconstituted stone porch. The rear of the building features 19th-century two-light stone mullioned windows to the main range and the rear wing. 20th-century lean-to extensions in reconstituted stone are present to the front and rear, and are not considered to be of special interest.

The interior has been altered in the late 20th century; the inglenook fireplace has been rebuilt with concrete block. The roof structure in the original 17th-century bay is partly plastered but retains its original trusses and purlins, with some pre-19th century common rafters visible.

The original building appears to have been a single-cell cottage dating from the 17th century, extended with a further bay parallel to the main range in the early 19th century and by the addition of a wing to the rear at the same time. It was later divided into two dwellings and then reverted to a single house in the late 20th century. Single-story lean-to extensions were added in the 20th century, and some internal alterations were made during that period.

The building is designated at Grade II for its substantially intact vernacular 17th-century cottage with good quality details, the 19th-century extensions that add to its special interest, and the retention of the early roof structure and original plan form, which outweigh the later 20th-century interior alterations.
