Chairs with adjustable height, glass windows that quietly open and close, carpet on floors and walls up to the windows, battery operated lights that are mounted to the ceiling, 6' 6" height on front end, window guards on the outside that don't allow water to easily come in the window when they are open, shelves that fold up and can be fastened closed and are along the top and out of the way, a small fold down shelf below the front window that will hold cell phones, cup holders in the corners, built tight where wasps can't build nests or try to winter, a small porch, and anchored down where the house is rock solid...at least that's what I wanted and built last year.
