25 Holywell Street

25 Holywell Street is a house that likely dates back to the 17th century but has undergone alterations. It is three stories high, constructed with stuccoed timber framing resting on a stone plinth, and features cellars. The building has a moulded eaves cornice and a parapet, with an overhang at the first floor that also has a moulded cornice. On the ground floor, there are two three-light windows; one has casements while the other features sashes. The front doorway is framed with moulded wood and topped with a scroll-bracketed hood. The first and second floors each have two bay windows with double sashes, all set in moulded wood frames.

Adjacent to this house on the north is a smaller two-story rubble house that likely dates from the 16th to 17th century. This building has modern brick coping and a Welsh slate roof, which includes a dormer with a two-light casement window. It features two brick stacks and on the ground floor facing north, there is a four-light stone-framed window with moulded mullions and a transom. To the east of this window is a recessed opening with a four-centred head, which is probably a blocked doorway, topped with a square label. On the first floor facing north, there is another four-light stone mullioned and transomed window. The roughcast west gable end has a projecting stack, while the northeast gable is patched in brick and contains a three-light stone mullioned window. This smaller building is also included in the Grade II listing.

Inside the house to the north, there are features from the 17th century, including panelling, doors, and a fireplace. All the listed buildings on the north side of Holywell Street form a cohesive group.
