Home in a Kit

Between 1908 and 1940, Sears, Roebuck, and Co. sold 70,000 homes through their catalogs. These were called Kit Homes, and they ranged from simple one-story cottages to elaborate two-story homes with columns and fireplaces. The house arrived in pieces in a boxcar. And they helped spark the first wave of suburbia. Host Kevin O'Connor speaks with Rosemary Thorton, author of The Houses That Sears Built, and Avi Friedman, author of Pre-Fab Living, about this then-groundbreaking concept. How did the kit home answer a booming need for affordable and modern housing? And why did their popularity disappear? And is there a place for a modern kit home today as we face yet another housing crisis? Learn more about your ad choices. Visit

The Perfect Tree?

There was a time when the American Chestnut was a plentiful resource for the wood that built our homes. In the early 1900s it was found in house framing, windows, trim furniture, and more. At 100 feet tall and up to 10 feet wide, it towered over the eastern forests. But then it disappeared. And now there's a movement to bring it back. Host Kevin O’Connor gets the story from author Susan Freinkel, who shares the historic importance of the Redwood of the East. We learn about the cutting-edge technology that scientist Bill Powell is using to bring it back from extinction. We also talk to Rex Mann, who grew up in Appalachia with the American Chestnut and researcher Sara Fitzsimmons who is overseeing an orchard of new growth trees. Learn more about your ad choices.
