Neo-eclectic architecture combines a wide array of decorative techniques taken from an assortment of different house styles.
It can be considered a devolution from the clean and unadorned modernist styles and principles behind the Mid-Century modern and Ranch-style houses that dominated North American residential design and construction in the first decades after the Second World War.
Details such as heavy moldings and/or trim (that would be cut stone or plaster in traditional architecture) are usually extruded foam with a stucco veneer.
An important development leading to the modern Neo-Eclectic style is the popularity of EIFS, a form of external insulation that is easy to apply and can be coloured and shaped to appear like an array of different materials such as stucco and stone.
[3] Typically and somewhat deceptively, the Neo-Eclectic style plays an instrumental role in making cheaply built, over-sized tract homes on comparatively small parcels of land appear as something far greater than the sum of their parts.
