In its original form Marlborough House had just two storeys. This illustration of c.1750 shows the garden front.
This view of the entrance front published in the 1850s before Pennethorne's additions shows an additional storey on the wings. The wings later gained a fourth main storey, and the central section gained a third.

St James's is a central district in the City of Westminster, London, forming part of the West End. The area was once part of the northwestern gardens and parks of St. James's Palace. During the Restoration in the 17th century, the area was developed as a residential location for the British aristocracy, and around the 19th century was the focus of the development of their gentlemen's clubs. Once part of the parish of St Martin in the Fields, much of it formed the parish of St James from 1685 to 1922. Since the Second World War the area has transitioned from residential to commercial use.
