Blacksmith's shop, office and stores at Powis Estate Timber Yard, with boundary wall to yard.

The blacksmith's shop, office, and stores at the Powis Estate Timber Yard were built as part of improvements made to the estate timber yard around 1830 to 1840.

The exterior features a gable that faces the yard and is built over the boundary wall. The lower courses of the boundary wall are made of thin-coursed local sandstone, while the upper courses consist of larger blocks. The continuation of the wall that forms the boundary with the canal towpath is made of brick, buttressed, and likely a later 19th-century reconstruction. The building itself is constructed from rough random local rubble and has a slate roof with brick star-shaped stacks on both the axial and end wall. There are double doors with a cambered lintel leading to the first floor, which is accessed via an external stone staircase with a cast-iron railing. A 3-light casement window, which has been renewed in the original camber-headed opening, is located next to the doorway, along with a clock positioned in the gable apex. The ground-floor smith's shop is entered from outside the yard on the east-facing elevation, featuring a doorway towards the center, a small window to the left, and an advanced gabled wing to the right. The rear elevation includes three windows on the ground floor with cambered heads and a long workshop-type window with overlapping small panes to the left.

Inside, the blacksmith's shop is divided into two rooms: the main smithy, which has a raised hearth against the north gable wall, and a machine room. The gabled extension at the front previously housed a shoeing pit. The first-floor office and store room are accessed from the external staircase at the gable end.

This building is a highly interesting part of the timber yard and is particularly notable for its design that combines different functions, making it an exceptionally well-preserved blacksmith's shop.
