18, Guinea Lane

No. 18 Guinea Lane is a terrace house built in the late 18th century, with some 20th-century additions. The front is made of limestone ashlar, while the rear is constructed from rubble. It features a double pile parapeted roof covered with Welsh slate, and there are two ashlar stacks on the left that are shared with No. 19 Guinea Lane.

The exterior is three stories high and has a single bay with three windows. On the first floor, there are three grouped sash windows: a four-over-four, a six-over-six, and another four-over-four, all set in splayed reveals with a continuous stone sill. The second floor has a six-over-six sash window in a splayed reveal with a stone sill and a 20th-century balconette. The ground floor features a six-over-six sash window in a plain reveal with a stone sill on the left, and on the right, there is a six-panel door with flush beaded and glazed panels in a chamfered reveal. The building has a band course above the ground floor, a moulded eaves cornice, and a coped parapet that continues with Nos. 19 and 20 Guinea Lane. The rear elevation is partially visible and has 20th-century windows.

The interior was partially inspected in the 1990s, which noted an exceptionally fine fireplace in one room, but no further details were provided.
