Spencer House is one of the greatest architectural landmarks of London and is an important surviving example of the London mansions of the nobility. This first in-depth study documents the history of the house, starting with the work of its architects, John Vardy and James 'Athenian' Stuart. Friedman chronicles the history of its owners, the Spencer family and looks at the house within the social history of eighteenth-century London. The survey concludes with a detailed account of the Rothschilds' recent restoration of the house led by David Mlinaric. It is sumptuously illustrated throughout with pictures of the interiors, architectural drawings, portraits and maps.
