This folder contains correspondence relating to the widely publicized development of Edison's poured concrete house. Much of the material consists of unsolicited inquiries regarding the unique nature, quick construction, and low cost of the projected house. Also included are letters concerning designs for the house, sample blueprints, and requests to view Edison's one-quarter scale model. Many of the unsolicited letters contain Edison marginalia, usually indicating that a circular be sent in response.

Less than 10 percent of the documents have been selected. With the exception of a few samples, unsolicited inquiries have not been selected.
