Sears Sold You a House by Mail, in a 30,000-Piece Boxcar Kit

In 1908 Sears, Roebuck & Co. published its first Book of Modern Homes and Building Plans. Forty-four house designs were available by mail, ranging from $360 for a small bungalow to $2,890 for a substantial two-story with porches. You filled out a form, sent the money, and a boxcar arrived at your local rail siding with everything you needed to build the house.

"Everything" meant about 30,000 pre-cut framing pieces, all the lumber milled to length and labeled, plus plumbing fixtures, electrical wiring, doors, windows, varnish, paint, and up to 750 pounds of nails. The whole kit weighed roughly 25 tons. A buyer with a few helpers and the included instruction book — which Sears claimed an inexperienced builder could follow — could put the house together in a few months.

The scale matters. Between 1908 and 1942 Sears shipped over 70,000 of these kits across the United States and Canada. Whole neighborhoods in places like Carlinville, Illinois (the Standard Addition, built for Standard Oil employees in 1918) are mostly Sears houses. Many are still standing. Most owners don't know their house arrived in pieces by train; the construction quality was high and the designs are indistinguishable from period custom builds.

The Depression killed the program more than any technological shift. Sears extended liberal credit to homebuyers through the 1920s, then watched its mortgage book sour after 1929. The company stopped offering kits in 1942 and quietly closed the books on a business that had, for three decades, made it the largest residential builder in the country by units shipped — without ever swinging a hammer.
