The piano nobile is the principal floor of a palazzo. This floor contains the main reception and bedrooms of the house.
Characteristics
The piano nobile is usually the first storey, or sometimes the second storey, located above a ground floor containing minor rooms and service rooms. The reasons for this were so the rooms would have finer views, and more practically to avoid the dampness and odours of the street level. This is especially true in Venice, where the piano nobile of the many palazzi is especially obvious from the exterior by virtue of its larger windows and balconies, and open loggias. Examples of this are Ca' Foscari, Ca' d'Oro, Ca' Vendramin Calergi, and Palazzo Barbarigo. Larger windows than those on other floors are usually the most obvious feature of the piano nobile. In England and Italy, the piano nobile is often reached by an ornate outer staircase, which avoided for the inhabitants of this floor the need to enter the house by the servant's floor below. Kedleston Hall is an example of this in England, as is Villa Capra "La Rotonda" in Italy. Most houses contained a secondary floor above the piano nobile, which contained more intimate withdrawing and bedrooms for private use by the family of the house, when no honoured guests were present. Above this floor would often be an attic floor containing staff bedrooms. This arrangement of floors continued throughout Europe for as long as large houses continued to be built in the classical style. This arrangement was designed at Buckingham Palace as recently as the mid-19th century. Holkham Hall, Osterley Park and Chiswick House are among the innumerable 18th-century English houses which employed this design.
Secondo piano nobile
In Italy, especially in Venetian palazzi, the floor above the piano nobile is sometimes referred to as the "secondo piano nobile", especially if the loggias and balconies reflect those below on a slightly smaller scale. In these instances, the principal piano nobile is described as the primo piano nobile to differentiate it. Though often found, this usage is potentially misleading: rooms in the piano nobile are always the grandest, less so those in the secondo piano nobile. The term is not used in Britain.
Beletage
In Germany, there is the :de:Beletage|Beletage, which fulfilled the same function as the piano nobile. Both date to the 17th century.
