This folder contains correspondence and other documents relating to the widely publicized development of Edison's poured concrete house. Most of the selected items concern the application of Edison's concept by housing developer Frank D. Lambie. Included is a brochure by the Lambie Steel Form Co. containing testimonials by Edison and by Robert A. Bachman of the Edison Storage Battery Co. Also included is a letter from railroad builder Arthur E. Stilwell.

Approximately 10 percent of the documents have been selected. The unselected material consists primarily of unsolicited correspondence that received a perfunctory response or no reply from Edison.
