20, Highfield Road B15

No 20 Highfield Road is a large detached stucco villa built around 1840. It stands two storeys tall and has a square three-bay plan, with its main entrance facing Westbourne Crescent and a rear entrance added around 1855 along Highfield Road. The main elevations feature a plinth, quoin pilasters, and a first-floor plat band. The flat eaves extend forward over the pilasters. The hipped slate roof is topped with stucco chimney stacks.

The first-floor windows are set in architrave surrounds with cornices supported by consoles. On the entrance front, the ground floor has a former doorway that has been converted into a window, flanked by canted bays that likely date from around 1855. These bays feature dentil cornices and faceted keystones. The current arched entrance is located in a single-storey annexe with reset panelled reveals.

The garden fronts to the south-west and north-west have French windows in architrave surrounds on the ground floor, which are screened by fine verandahs made of cast iron. The south-west verandah has eight bays, while the north-west has five bays, both topped with leaded tent roofs and decorated with scrollwork and coupled standards with openwork entablatures. The wing added around 1855 on Highfield Road includes four windows in architrave surrounds and a billiard room situated above the former coach house.
