This has been my home away from home for the past four years.
It's 11 feet to the floor (from the ground) - the platform is 6 feet wide (across the front) and 8 feet front to back - the roof peaks at about 7 feet high so I can stand up and stretch. It's fastened to the three main trunks of pine tree (they form a triangle shape about 4 1/2 feet between each trunk at the height I built the stand at.
It's nothing more than 2X4" lagged into the tree trunks - 2X3 frame for the walls covered with chip board. The roof is 2X2 frame covered with corrugated plastic panel then covered with a camo tarp. The panels were painted with deck stain (left over cedar colour) then I took a can of green and black spray paint and went at it - added a bit of 3D camo material here and there - access is with an aluminum step ladder, likewise, spray painted black (mostly).
After the first few months of being there it went ignored (witnessed by the couple of game cameras I have set up) by the deer, bear and other "critters" where it is - now it's "something that is there that doesn't do anything to them".
If you have somewhere (secure and private) to set up, I say "go for it" - if you are comfortable you can stay out forever...
