Abstract: A climate-controlled communications-work booth for use as a local office by travelling salesmen, businessmen and the like. The booth is provided with a molded contoured chair, and a work table therein on which a telephone is disposed. Access to and exit from the booth is controlled by an electronic credit card-operated lock system, controlled by a computer, which automatically opens the booth door to permit the user to enter. The booth is preferably constructed of ferrocement, and has the climate control and electrical equipment encased in detachable modules. When a user leaves the booth and closes the door, the computer measures the time of use in the booth and the amount of telephone calls made therein and renders the user a monthly bill charged to his credit card.
