The transition from the last decades of the 19th century into the 20th saw an increasing vocabulary of residential architectural types and styles. The rather austere and rigid classicism of the early 19th century was slowly replaced with buildings more organic in form. Various wings, dormers, or turrets sprouted from the central core on houses as asymmetry became more fashionable in Victorianism.
But the turn of the 20th century ushered in a modern era of architectural design. Suddenly, houses with all the appendages and accoutrements of the Victorian era looked ungainly and old-fashioned, and the less visible and intrusive on the landscape a house was, the better. The transition was not drastic, but basic forms began to simplify. The Prairie School style developed by Frank Lloyd Wright with its low-to-the ground, simple lines influenced the then-developing bungalow. This house type—and not just the Prairie School influenced version—became the house of choice and neighborhoods sprung up everywhere in the state. Following World War I, historical reference became important again in the public taste of architecture as various European and other cultural influences played into the design of the next most popular house type in Utah, the Period Cottage.
During this era economics played a role in the vast numbers of houses being constructed, but also the relative decrease in size of the average house to meet the planning needs of communities. However, no matter what city or town one travels to in Utah, one will likely find several examples of houses from this era!
