After reading How do I do the car-door-sukkah trick?, i wondered: isn't this building it on Sukkot?
So, is it permissible to build a succah on Sukkot?
I originally thought no, because i know that the succah is muktzah for all of chag. Also, per When can you build the sukkah?, it seems that it should be done within 30 days of the chag.
