106, Harley Street W1

No. 106 Harley Street is a terraced town house built around 1776-77 as part of the Portland Estate development by John White. The building features stock brick construction with a channelled stucco ground floor and a slate roof. It has four storeys, a basement, and a dormered mansard, with a three-window wide front. To the right, there is a broad semicircular arched doorway adorned with Coade vermiculations and a head keystone, leading to a panelled door with sidelights and a cornice-doorhead beneath a patterned fanlight. The windows are recessed sashes set under flat gauged arches. There are plat and sill bands above the ground floor, a cornice above the second floor, and a crowning modillion cornice with a blocking course. An early 19th-century cast iron balcony spans the first floor, and wrought iron area railings with urn finials complete the exterior.

Inside, the house boasts a fine interior with elaborated features typical of high-quality homes. Highlights include a top-lit stone geometrical staircase with an openwork wrought iron baluster pattern and swag ornamentation on the skylight drum. The plasterwork includes enriched friezes and ceilings, as well as stucco mythological medallions with wreath and ribbon embellishments above statuary marble chimneypieces featuring Ionic columns in the first-floor front room and pilasters in the ground-floor front room. The interior also includes mahogany doors with chased furniture.
