 In 1650 at Coleshill House Pratt designed the first purpose-built servants' hall in the basement.By the end of the century the arrangement was common; the only servants left in the hall were those waiting for a summons.By the late 17th century, the idea of giving servants their own designated areas had been adopted not only in the houses of the aristocracy, as at Coleshill, but also in those of the gentry such as Belton House.
