Description
The Pump House is a small, single-storey building designed in the Arts and Crafts style, featuring a pyramidal roof. It has two double boarded entrance doors located in the southwest corner. The walls are roughcast, and the slate roof has exposed rafter ends, cast iron rainwater goods, plain ridge tiles, and a vent at the apex. Each slope of the roof includes a flat-headed six-light dormer and a triangular ventilator above.
The building is enclosed by a rubble stone wall along the lane to Cranford and has a partly subterranean reservoir attached to the north. Originally a single space, it is now divided. Inside, there is a Tangye Type ‘V’ vertical engine situated behind a display window, along with pipework and a low-level door leading to the reservoir in the accessible area. The underside of the roof is simply boarded, with the central boss decorated with the emblem of the Friends of Pembrokeshire Coast National Park.
