The city of Madrid utilizes their pedestrian paths in an interesting way. The corner shown below contains a water closet, or toilet. Anyone who walks by can use it for a minor fee of about one Euro. For this design project, the water closet kiosk is placed in a grocery parking lot in Anderson, Indiana. There are some minor changes to it of course, to fit the American ways of life. The kiosk in America would include sections in the rear for an ATM and a mailbox. A compartment in between the two would allow service to both areas. Two pickup boxes for the restroom waste protrude from both rooms. Pickup involves a vacuum system, keeping away unpleasant odors. The restroom interiors will contain thermal mass along the walls to trap heat during the day and release it at night, the light source being the windows surrounding the cap of the kiosk. For added heat in the winter, a small radiator is located on the wall. In addition to the interior thermal mass, there will be a layer of insulation between the outer and inner plastic shells that make up the wall.
