23, Calthorpe Road B15

23 Calthorpe Road is a notable early villa from the Calthorpe estate, dating from around 1820 to 1830. This detached building has two storeys and three bays, featuring a stucco façade with the entrance located on the left side. It has a plinth, a first-floor sill band, flat eaves supported by broad shallow modillion brackets, and a hipped slate roof with stucco chimney stacks.

The ground floor windows and doorway are set within round arched panels, complete with inset sills and aprons extending down to the plinth. The rounded heads of the windows have glazing bars radiating from them, while the first-floor windows are plain glazing bar sashes. The doorway features panelled reveals and soffit, showcasing a Birmingham-style inset doorcase with Tuscan columns supporting an entablature that has a modillion cornice, along with a radial glazed fanlight above.

To the left, there is a lower two-storey wing that has a moulded cornice and blocking course. A screen wall with an arched side entrance on the right connects to a two-storey coach house, which has segmental arched doors and projecting eaves. The garden front was altered around 1860 to 1870, incorporating canted bays and an Italianate garden door situated between them.
