Who should build a sukkah? Should a certain person do it?
There is controversy if the placing of the sechach can be done by some3one who is not obligated in the mitzva, such as gentile women and children. Therefore there is a prefferance that it be done specifically by Jewish adult men. This only applies to the placing of the sechach, but not to the building of the walls.
