10, South Street

10 South Street is a late 18th-century building, notable for being the house of the Mayor of Casterbridge in Thomas Hardy's novel. It is constructed of burnt grey brick with red brick dressings, featuring a plinth with chamfered stone capping. The building stands three stories high and has a three-window front that is set back from the main frontage line.

A particularly fine late 18th-century doorway is present, characterized by a round-headed opening with a fluted archivolt. The transom above the door is adorned with guilloche enrichment, and there is a fanlight above. The doorway is supported by moulded console brackets that feature beading and foliage enrichment, with paterae located on the entablature blocks above the brackets. The cornice and pediment are decorated with dentils, while the tympanum showcases swag and paterae carving. The eaves cornice is moulded and includes fluting and additional paterae.

The ground floor windows and the central first-floor window are round-headed, complete with stone keys and imposts. The building retains its original rainwater heads and downpipes.
