1, Lansdowne Walk W11

House. Constructed between 1843 and 1845 by James Thompson, it was extensively altered and enlarged in 1900 by Aston Webb, who used the building as his own residence. The house is built of brown brick with red brick dressings and a channelled stucco ground floor; it has hipped and gabled slate roofs and red brick stacks with stone banding. The design is irregular, extending around a corner with its principal facade facing Ladbroke Grove. It rises two to three storeys.

The bay to the right features a segmental-arched tripartite sash window above a boldly projecting canted bay with a Venetian window. Below this is a porch with Tuscan columns supported on spur walls, leading to a panelled front door set within an eared and lugged architrave, flanked by small one-light windows. A central square tower has flat gauged brick arches over a second-floor tripartite sash window, first-floor eight-pane sashes, and a ground-floor tripartite sash window with radial heads to the central sash, flanked by Tuscan pilasters. The bay to the left has a polygonal bay window with iron grilles and ball finials to the parapet, terminated by a large lateral stack. The Lansdowne Walk elevation features a large lateral stack to the corner, two-light Geometrical windows illuminating the stair hall, and a tripartite sash above a panelled door with a decorative overlight. The garden elevation has a three-storey canted bay with sash windows.

The interior features panelled doors in panelled reveals. A fine, panelled hall contains marquetry panels to cupboard doors and the overmantle, and an eared architrave frames a moulded stone fireplace, complemented by a modillioned cornice and a decorative plaster ceiling with a wreathed panel. The staircase hall has geometrically-leaded windows and a partly stone staircase with a geometric pattern to the wrought-iron balustrade. A further inner hall showcases a parquet floor, a panelled dado, and a fine vaulted strapwork ceiling decorated with grotesques, arabesques and a spider within a large web. A south-facing drawing room has a moulded hood architrave to its fireplace, alongside a polygonal bay window with decorative plasterwork and benches set against a panelled dado. An Arts and Crafts frieze adorns the space, alongside panelled sliding doors leading to a breakfast room, notable for its moulded cornice and Georgian-style fireplace.
