The Italian Renaissance house plans style is found in early 20th century houses throughout the United States. It tended to borrow from and mimic the original homes of Italy more closely than the Italianate style which followed a more loose and free interpretation of Italian architecture. Many american architects and their clients, through first hand visits and experience with original models in Italy, help to bolster the authenticity of the mediterranean style in their recreations. Even more, because of improved printing technology, photos were also accessible. In stark contrast, the Italianate style was based on pattern book drawings created by those with no first hand knowledge of Italian homes.

Italian Renaissance house plans usually feature a number of common details. Hipped roofs, usually low in pitch and occasionally flat, with tile roof covering is the main feature. The overhanging boxed eaves are wide and supported by decorative brackets. This feature alone helps to separate the Italian Renaissance house plans from the other mediterranean styles. The facade is more likely than not to be symmetrical. The entry area usually has accents of small classical columns or pilaster. Arches or radius tops above doors and first floor windows are common. This is also seen on porches if one is included in the design. The upper story windows are normally smaller than the main floor windows and also less elaborate.
