18 Nott Square

18 Nott Square is an attached shop with living accommodation, featuring painted stucco and a slate roof with boxed eaves and a stuccoed stack on the right. The building is three storeys high and has a two-window range. The upper floor window bays are recessed between plain pilaster strips, and the original sashes have been replaced with 20th-century plate glass windows that include top-opening lights. The first-floor windows are longer than those of the adjoining building, No 19, suggesting they may have been lengthened. Stucco voussoirs are present above the upper windows.

The ground floor has a 20th-century plate glass shop front with a deeply recessed doorway to the right. This doorway features two plate glass doors: one leads to the shop in the side window to the left, and the other provides access to the accommodation at the end, both equipped with overlights. The shop front is framed by a mid-20th-century moulded stucco surround, and there is a late 20th-century plastic fascia.

The ground floor has been altered, and there is an enclosed stair to the right. A stair from the first floor is enclosed between the front and rear rooms. Additionally, there is one fielded-panelled four-panel attic door.
