23,25, Great Avenham Street

23 and 25 Great Avenham Street are a pair of small town houses built around 1825, with some alterations. They are constructed of red brick in Flemish bond, featuring sandstone dressings and a slate roof. Each house has a double-depth plan, is single-fronted, and includes back extensions with a central through-lobby. The buildings are two storeys high with cellars and have a symmetrical three-window range. They have a plain frieze and a moulded gutter cornice.

The doorways are arranged as a triplet in the center, with the lobby door positioned between them. Each doorway is round-headed, featuring gauged brick voussoirs, set-in Tuscan quarter-columns, and semi-circular fanlights with radiating glazing bars. The lobby doorway has a plain lintel and a board door. There is one window on the ground floor and three above, with the central window belonging to No. 23. The ground floor window of No. 23 is sashed without glazing bars, while the others have altered glazing. All windows have raised sills and wedge lintels, and the cellar windows also have wedge lintels and are protected by gratings. The houses feature gable chimneys. The rear and interior were not inspected. These houses are part of a formerly complete set of late Georgian lower-middle class homes in this street, which was laid out in Great Avenham Field and advertised for sale as building plots in 1825.
