American architectural giant Louis Sullivan coined the phrase "form follows function" and the concept was embraced by the arts and crafts or craftsman style of architecture early in the last century. Low-pitched rooflines, shed dormers, and some evidence of the interior structure flowing through to the outside are what define this style. The Craftsman Series of SmartWood™ timber frame home designs are perfect examples of this style and offer a broad range of sizes to fit your specific project.
