42, Langham Street W1

No. 42 Langham Street is a terrace house built in the latter part of the 18th century. It is constructed of stock brick and features a slate roof. The building has four storeys and a basement, and it is three windows wide. The entrance is located to the right and consists of a six-panel door with a rectangular fanlight above, all framed within an architrave surround. The windows are later 19th-century sash windows set back with stuccoed reveals, topped by flat gauged arches and supported by stone sills. The house has a stone-coped parapet, original cast iron area railings, and an iron boot scraper to the left of the doorstep.

Inside, the property retains an arcaded entrance hall adorned with plaster cornices. The open well staircase is illuminated by an oval radial glazed domed lantern. The staircase features shaped brackets at the ends of the treads, slender square balusters, and enriched friezes at each floor level. Additional original details include plasterwork cornices, fluted door architraves, panelled reveals, and shutters. Notably, the architect Benjamin Wyatt lived and worked in this house from 1810 until 1832, when he had to move due to bankruptcy.
