Expensive Mansion, Toronto, Canada

Until World War I it was not unusual for a moderately sized mansion in England such as Cliveden to have an indoor staff of 20 and an outside staff of the same size, and in ducal mansions such as Chatsworth House the numbers could be far higher. In the great houses of Italy, the number of retainers was often even greater than in England; whole families plus extended relations would often inhabit warrens of rooms in basements and attics. It is doubtful that a 19th century Marchesa would even know the exact number of individuals who served her. Most European mansions also were the hub of vast estates. A true estate (the medieval villa, French ville) always contains at least one complete village and its church. Large estates such as that of Woburn Abbey have several villages attached.
Nineteenth century development
The 19th century saw particularly in the United States a new type of mansion being built, often smaller than the older European mansions. The Breakers in Rhode Island is a fine example, as is the nearby, but completely different, Watts Sherman House.
Fifth Avenue at this time was lined with numerous mansions, designed by the leading architects of the day, many in European gothic styles, built by the many families who were making their fortunes, and thus achieving their social aspirations, in the mid 19th century. However, nearly all of these have now been demolished, thus depriving New York of a boulevard to rival, in the architectural sense, any in Paris, London or Rome—where the many large mansions and palazzi built or remodeled during this era still survive. Mansions built in the countryside were not spared either. One of the most spectacular estates of the U.S., Whitemarsh Hall, was demolished in 1980, along with its extensive gardens, to make way for suburban developments.
