 The only advantage of Neoclassical architecture from the servants point of view, was that houses once again began to have pitched roofs, which could contain servant's bedrooms with gabled windows, albeit often hidden behind a stone balustrade or parapet.This arrangement for housing servants persisted in the affluent town houses of Britain into the late 19th century and is particularly common in the great Regency terraces of Belgravia and Mayfair designed by John Nash and later Thomas Cubitt in London.However, in the country where there was more space, the more practical solution was to build a specific wing onto the house for the staff, and as it was often asymmetrical to the main body of the house, and of cheaper building materials, it became necessary to disguise it.
