Pump House

The Pump House is an early 19th-century structure built for the Earl of Harrington, likely designed by William Barron, and has undergone some later alterations. It is constructed of red brick on a stone plinth, featuring stone dressings. The roof is covered with red tiles and has distinctive parapets on the side walls that curve in at the eaves and out again at the top, along with flush parapets on the gable walls that rise to a central point. Both the side and gable wall parapets have been slightly lowered and capped with engineering bricks.

This single-storey, single-bay building has a waterwheel located on the east side. The south elevation includes a chamfered trefoil-headed doorcase with a plank door, above which is a cinquefoil-headed niche featuring a large 'H' topped by a coronet. The north and west elevations have cinquefoil-headed single light chamfered windows. The east side showcases a cast iron waterwheel with wooden paddles and a wooden rim, surrounded by a 20th-century brick wall topped with iron railings. Inside the building, the original pump is still in place.

This pump house was likely the first in a series of similar buildings constructed during the development of the elaborate gardens designed by William Barron between 1830 and 1860, which are listed in the Derbyshire Historic Gardens Register at Grade II*. In his diary, Barron noted that the work on the lake and water supplies were among his initial projects.
