Description

The Old Post Office is a two-storey house built from squared snecked rock-faced sandstone blocks, featuring a cogged band between the floors and a Welsh slate roof. It is part of a terrace of railwaymen's cottages, specifically Nos. 1-4 Nantyderry Cottages. This building consists of two bays and may have originally been two separate cottages before being converted into a shop.

On the left side, the ground floor includes an 8 over 8 pane sash window with an elliptical head and a plank door to the right. Above, there is a sash window with 2 over 2 horizontal panes and an octagonal-shaped head, set within a gable. The right side features a two-storey gabled wing that projects out. The ground floor has a shop window with 4 x 4 panes, and above it is a larger sash window with 2 over 2 panes and a similarly shaped head. The roof is steeply pitched and has brick stacks located on the left and in the centre. The rear elevation has not been seen. The interior was not inspected during the resurvey.
