Kilgetty Colliery Weighbridge Office

The building is 5 m square, single storey, of only one room, with walls very slightly battered outwards, of rubble construction with dressed stone quoins. It is set on a platform two steps above the road at the front, being built into the rock at the E end and elevated where the ground falls away to the W. It is gabled, with a replacement corrugated-iron roof and a small brick chimney at the E end. It has one small nine-paned casement window and a plank door to the front, all the joinery replaced. A blocked doorway to the rear and a blocked window to the E. The W side has a wide fixed light window at a low level. The weighbridge platform position is no longer apparent and the pavings and falls in the vicinity have been much altered.
