Pumping House At Ncb Mines Drainage Unit

The pumping house at the NCB Mines Drainage Unit, dated 1823, is now used to house electrical apparatus. The structure is built from coursed, dressed sandstone and features a Welsh slate roof. It consists of a rectangular tower with a lean-to and workshop buildings to the right. The roadside elevation showcases a two-storey tower and lean-to, along with single-storey workshop buildings. The tower has a gabled entrance with a renewed glazed door set in a round-arched opening, featuring the date inscribed on the voussoirs. There is a continuous impost band, and on the first floor, an iron casement with glazing bars is found within a round-arched opening, which is now partly obscured by a brick and concrete gantry attached to the front. The lean-to on the right has a casement with glazing bars on each floor. The low workshop buildings to the right retain remnants of two infilled round archways, with the right arch truncated by a later short gabled projection, and a two-window section to the far right that is also of later construction. The rear of the building has similar round-arched openings, although the sills have been altered. The interior no longer contains the original pumping machinery, and the 20th-century workshop buildings attached to the rear right are not of special interest. This pumping house was part of the Fitzwilliam mining enterprises in the area.
