I plan to enclose in the winter, but there is no electric so it would be very dark inside. so part of the open walls is the ability to work in light spring, summer, and fall. our winters can be really wet so having the side walls on down to the bottom boards well help increase the life of my boxes. So the main two reasons for the shed are first: summer time sun beating me to death and then winter rain ruining my wooden ware. I also store supers inside in winter. i recently painted that western wall white to reflect the sun. the other 3 walls i will paint darker for winter sun. just a fun project because i had a goat shed but sold my goats. this only cost around $80, using all new wood, that is only 3/8 plywood I believe so not very expensive. so it cost me what? 8 quarts of honey to build?
