I'd assume that there's certain requirements for the size of exam rooms based on an understanding of the equipment and exam tables, as well as privacy considerations: the doors should not open into a space visible from the waiting room for instance. How do you design the waiting area to put people at ease before a potentially intrusive and stressful medical exam? Does the client have the ability to bring personal items into the exam room or are their cleanliness requirements that preclude this and require you to design a coat room with storage?
