No 1 The Old Post Office, and 2 and 3, Main Street

No. 1 The Old Post Office, and Nos. 2 and 3, Main Street, is a row of three houses dating from the 17th century, with No. 1 specifically dated 1651, and featuring mid-18th century and late 19th century alterations. The buildings are constructed from gritstone and have a graduated stone slate roof. They are two storeys high and have five first-floor windows. The facade is divided in the center by a row of quoins, separating the right-hand pair of houses (Nos. 2 and 3) from the left.

The left range includes a board door set in a narrow quoined opening with a three-centred head, featuring the raised letters "W 1651 H". To the left, there is a three-light flat-faced mullion window on both the ground and first floors, alongside a six-pane shop window that has been built into a blocked quoined segmental-arched cart entrance. There is also a four-pane sash window to the left on the ground floor and two four-pane sashes above. The right range consists of a mirrored pair of cottages, each with board doors in plain surrounds and large lintels on either side. Between the doors are two three-light flat-faced mullion windows on each floor. The buildings have stone gutter brackets overall and four ridge stacks: one to the left of the mullion windows, one in line with the division between Nos. 1 and 2, one between Nos. 2 and 3, and one on the right gable. The interior was not inspected during the resurvey.

Nos. 2 and 3 were likely part of a 17th-century farmhouse, while No. 1 served as a barn and byre range, dated 1651 and possibly constructed by a member of the Hewitt or Hammond families, who were significant landowners in Threshfield during the 17th century. The division of the property into three cottages in the 18th century reflects the demand for accommodation for miners from Grassington at that time.
