Yarnbury House

Yarnbury House is a house and office, now used as a house, likely built in the late 18th century with an early to mid-19th century extension and alterations. It is constructed of grey gritstone rubble and has a grey slate roof. The original two-storey, two-bay house features quoins and has been extended by one bay to the left, with an additional bay (possibly a former cottage) further to the left. A central porch was added in the mid-20th century, featuring a door surround that was reset from the main body of the house; it has a 20th-century panelled door with a fanlight in a plain stone surround with a keystone.

The windows throughout are fitted with 20th-century small-pane frames, each having slightly projecting plain stone surrounds. There is one surround to the left of the entrance and two to the right, with a larger small-paned window above the entrance. The walling shows evidence of a blocked doorway on the far left and between the right-hand windows on both the ground and first floors. Other architectural details include stone gutter brackets, plain kneelers, gable copings, and four ridge stacks located at the ends of the original building, to the left of the current entrance bay, and to the left of the windows on the far left.

The two right-hand bays may have originally been built for agricultural or industrial purposes in the 18th century. The lead mining industry on Grassington Moor experienced significant changes starting in 1779 when Cornelius Flint, the Duke of Devonshire's Mineral Agent, began constructing new drainage systems. It is believed that either Flint or his local agent lived at Yarnbury House and operated offices within the building. In 1818, John Taylor became the Duke's Chief Agent and appointed Captain Larratt from Cornwall as the local agent. The extensions to the house likely date from this period of growth in the mining industry, and the large window above the entrance is said to have illuminated the office where the agent conducted business with the miners. The years 1828 to 1833 marked another period of significant construction expansion in the area.
