16, Castle Park

No. 16 Castle Park is a house, formerly two houses, that was originally part of a row of five and is now used as offices. It dates from the mid-18th century and was raised and altered in the 19th century. The building is constructed of sandstone ashlar with ashlar dressings on the front and side, while the rear is made of coursed rubble with a rendered second storey. The slate roof is hipped to the left, featuring a chimney set back towards the rear and a gable chimney stack to the right.

The building has a T-plan layout with a double-depth front range and a two-storey bow window on the back wall to the left. There is a rear wing that extends into a former outbuilding. It has three storeys above a cellar and consists of six bays under an eaves cornice. The doorway is located in the third bay and features chamfered quoins to the left, with additional quoins on the second floor above the junction with No. 14. The sill bands on the first and second floors extend around the left-hand gable wall, where there is a window on each floor. All the windows, as well as the doorway, have moulded architraves and are sashed without glazing bars.

Access to the doorway is via a flight of four steps, which are flanked by cast-iron railings with turned balusters and standards topped with urn finials. The recessed door has nine panels and an integral overlight. Rebuilt stonework to the right of the door, along with the Ordnance Survey map surveyed in 1845, indicates that there were originally paired entrance doorways in the two central bays.
