hey rick i rebuild my tree stand about every 3 years and what i do is look for three or four trees that are close together and go from there... i get a big ladder climb up one of the trees and connect all the trees together with a couple boards then i put the floor in. then as for the "boxed in" part i get whole pallets of wood and just nail them to the sides. and for extra i put built in seats in mine lol hope this helps a little
