Queen Anne architecture, for the purposes of this blog, is a primarily residential Victorian style. It is unrelated to the late Baroque architecture in England also known as "Queen Anne." Highly eclectic and probably what a layperson imagines when they think "Victorian house," Queen Anne architecture is one of the best known styles of Victorian architecture.
Queen Anne architecture became popular in the 1880s, supplanting the Second Empire and Italianate styles. It stayed in use until about 1900, being replaced by later Shingle and Richardsonian Romanesque designs.
Queen Anne designs are noticeable by several characteristics. Their expression is very eclectic, as the buildings are usually asymmetrical, and features such as bay windows and turrets/towers reduce the amount of blank walls. They can be highly ornamented through Eastlake spindlework, decorative panels, and brickwork.
