【单选题】The house style that dominated American housing during the 1880s and 1890s was known as Queen Anne, aname for an American style. The name was, in fact, a historical accident, originating with fashionable architects in Victorian England who coinedwith apparently no reason other than its pleasing sound. The Queen Anne style was loosely based on medieval structures built long before 1702, the beginning year of Queen Anne’s reign. 
A distinctive characteristic found in most Queen Anne houses is the unusual roof shape - a steeply pitched, hipped central portion with protruding lower front and side extensions that end in gables. It is often possible to spot these distinctive roof forms from several blocks away. Another feature of this style is the detailing, shown in the wood shingle siding cut into fanciful decorative patterns of scallops, curves, diamonds, or triangles. Queen Anne houses are almost always asymmetrical. If you draw an imaginary line down the middle of one, you will see how drastically different the right and left sides are, all the way from ground level to roof peak. A final characteristic is the inviting wraparound porch that includes the front door area and then extends around to either the right or left side of the house. 
Queen Anne houses faded from fashion early in the twentieth century as the public’s taste shifted toward the more modern Prairie and Craftsman style houses. Today, however, Queen Anne houses are favorite symbols of the past, painstakingly and lovingly restored by old-houseand reproduced by builders who give faithful attention to the distinctive shapes and detailing that were first popularized more than one hundred years ago.
