Banff: the cabin stayed. The rotting deck did not. Cedar floor and a full wood rail when we left.

Mountain snow load, freeze-thaw, and a drop that had nothing between you and the spruce. We pulled the grey boards, set posts, and ran a full wood rail on every open side and the stair. Cedar floor, hidden fasteners, flashing that will still work in April. The Bow Valley is the view; the rail is why you can use it.
