The trusses in classic stick-frame construction are typically spaced 2 feet apart. Trusses placed 8 feet apart may appear strange to many traditional stick-frame builders, but because to the genius of contemporary engineering, it is a relatively popular construction style. The American Institute of Architects currently recommends that trusses for stick frames be installed at least 12 inches off the ground, which allows room for people to walk under them. In addition to being easy to build, stick frames are also efficient structures that use very little material per square foot of building surface. On average, a stick frame will use only one-third as much lumber as a comparable frame built with traditional methods. The posts and beams that make up a stick frame are usually all made from a single tree, making this type of architecture environmentally friendly. It's no wonder so many classic houses in America are stick frames! You can learn more about stick frames at museums and other heritage sites all over the country. There are even some modern house designs that continue to use these effective structures!
