My buddy up the road from me has a sick ass shack in his backyard. First off, his house is above it on a slope, but there's a few enormous redwood trees that block all the back windows. We built it on stilts out of 4x4 inch posts and cross-supports, and built a 14x12 foot deck and on top of that we built up a 6x5x7 foot shack, fits 5 people easy and it's virtually..."Invisible". their property's surrounded by woods a stream and tons of foliage. the ultimate smokehouse...no pun intended.
