The Mill Cottage

The Mill Cottage is a building that originally served as a miller's house and is now used as museum offices. It likely dates from the mid-18th century, with some alterations and additions made in the 19th century. The structure is built of rubble-sandstone and features a stone slate roof. It stands two storeys high and has three windows on the first floor, with a wing extending to the rear left and a single-room addition set back to the left.

The main range of the cottage has large quoins and a central doorway that is quoined with a deep lintel. On the right side, there are two 2-pane sash windows, with an altered doorway beyond. On the left side, there are paired 2-pane sashes set in a stone mullioned surround. The first-floor windows, similar to those on the ground floor to the left, rise above the eaves as flat-topped dormers. The left side features shaped kneelers and chamfered gable copings that rise to a brick end stack, which is built onto the original external end stack that has offsets. There is also a brick ridge stack located between the second and third bays.

The addition set back on the left includes a 4-panel door in an ashlar surround, with a small 4-pane sash window to its left and a brick end stack. The rear wing has a left return that features tripartite and paired sash windows. The addition set back on the right of the main range is not of special interest but is included for its group value.
