William Kingdom (fl. 1840s-50s) was a property developer who was active in the development of tracts of west London in the mid-nineteenth century. These included the Westbourne area where he worked with Thomas Marsh Nelson on Westbourne Terrace,[1] areas north of Craven Road, and most of Gloucester Terrace between 1843 and 1852.[2] He may also have developed Hyde Park Gardens, Paddington.[3]
