Paragraph # 1
Wood has long been a popular building material in North America because it has generally been plentiful and cheap. Swedish settlers in Delawere built log cabins as early as the 1630s. In New England, British colonists built wooden "saltbox houses." Most of the wooden homes of Colonial times could be built with simple tools and minimal skills.
In the early nineteenth century, the standard wooden house was built with beams set into heavy posts and held together with wooden pegs. This method of construction was time consuming and required highly skilled workers with special tools. The balloon-fame house, invented in 1833 in Chicago by a carpenter from Hartford, Connecticut, used a framework of lightweight lumber, mostly 2x4 and 2x6 inches. This type of house could be assembled by any careful worker who could saw in a straight line and drive a nail.
This revolution in building was made possible by improved sawmills that could quickly cut boards to standard sizes and the lower cost of lumber that resulted. There were also new machines that could produce huge quantities of inexpensive nails. Skeptics predicted that a strong wind would send such houses flying through the air like balloons and at first " balloon frame" was a term of derision. But the light frames proved practical, and wooden houses have been basically built this way ever since.
