Changes to existing structures and specific design features for new structures are discussed as a means of making buildings usable by the physically handicapped. The author stresses the need for consideration of approaches, entrances and exits, and equipment and facilities which will allow the disabled to enter, leave and work within all types of public buildings. Experiments with wheelchair patients to set up criteria for ramps, floor covering, floor finishing, door mechanisms and hardware, water coolers, bathroom facilities, and desks are reported. A detailed work outline for American Standards Association Project A-117, co-sponsored by the President's Committee on the Employment of the Physically Handicapped and the National Society for Crippled Children and Adults, is included as an appendix.
