Yes, I built (mainly with my own two hands) it to last. "If you can't park a Sherman tank in the living room, and not have it fall into the basement, then A) the room is too small; B) the floor is too weak; C) BOTH." (You have to build it in, however; it would never fit through the door.)
My building philosophy is, "if a tree falls on it, the tree should either bounce or break; not damage the roof!" I believe that comes from my Romano-Germanic, Romano-Gallic, and Romano-Brittanic ancestry.
