Numbers 10 and 11 and Attached Walls

A pair of semi-detached villas with attached walls, built circa 1834-1838 and later altered, designed by William Thomas. The construction is primarily pinkish-brown brick with a painted stucco facade, topped with a Welsh slate roof. Cast-iron porches and verandahs are also present.

The villas are two storeys high, with a basement and attics to the gable, and feature six first-floor windows. The entrance bays on the left and right are set back. The first floor windows include narrow, round-arched 2/2 sash windows on the left and right, while the remaining windows are 6/6 sashes in plain reveals with sills. Windows on the right have blind boxes. A 10-pane French window with margin-lights is also present. The entrances lead to 3-panel doors, the left of which is partially glazed. A casement window is located in the basement. The facade incorporates a frieze, cornice, a low parapet, and central ridge and rear stacks. The porches are embellished with delicate scroll motifs. A continuous verandah runs along the centre of the ground floor, featuring a heart-and-anthemion balustrade and uprights decorated with anthemion-and-paterae motifs.

Inside No.11, a staircase boasts a wreathed handrail and rod-with-central-bobbin balusters. Some windows have shutters, and fireplaces are also a feature.

Screen walls on the left and right abut numbers 9 and 12 respectively.

Historically, number 10 was the residence of American author Nathaniel Hawthorne from 1853 to 1859. A map from 1834 depicts the layout of Lansdowne Circus and Crescent, intended for future development. Lansdowne Circus retains a largely complete layout of nearly identical villas. Numbers 1-17 are considered an architectural group with Victoria House, and numbers 19-57 in Lansdowne Crescent.
