Several popular housing styles emerged in the 20th century as building booms created entirely new neighborhoods on the outskirts of cities across the nation. One of the most popular house style is a modern house style. This modern house style represented a break with the formal house layouts of the past, and in most cases allowed owners more space, more privacy and more room for entertainment and leisure activities. A modern house style takes its design influence from art and architecture trends. Sleek and streamlined, modern houses feature functional materials and design that focuses on strong geometric shapes. The overall look of a modern style house is spare and never cluttered. The modern house style is often made of industrial materials, such as as glass, steel, concrete, aluminum, and plastic, though polished wood may be used as an accent.
The exterior of a modern house style is frequently a well-defined geometric shape. Cubes, rectangles, and even daringly angled structures are often seen in this type of design. Rather than separate from the walls as in many other design styles, the roof of a modern house style is typically flat and part of the overall geometric design. Windows may be small squares or rectangles, or the walls may be made entirely of glass.
