Description
No. 98 Harley Street is a terraced town house built around 1777 as part of the Portland Estate development, likely designed by John White in collaboration with the plasterer Thomas Collins, who were associates of Sir William Chambers. The building is constructed of stock brick and features a slate roof. It has five storeys and is three windows wide.
The entrance is on the left, marked by a semicircular arched doorway with Coade stone vermiculated rustications and a head keystone. The doorway includes a panelled door, sidelights, and a patterned fanlight. The upper floors have recessed sash windows beneath flat gauged arches. Architectural details include a first-floor plat band and sill band, a cornice above the second floor, and a modillion cornice above the third floor. A continuous cast iron balcony from the early 19th century adorns the first floor, along with cast iron plumbed spike finials.
Inside, the house retains several notable features typical of high-quality speculative houses from the 1770s in Harley Street. These include a top-lit stone geometrical staircase with a wrought iron balustrade, flute and patera friezes, and stucco mythological medallions over marble chimneypieces.
