These images should give you an idea of my plans for the cabin I'm building.  I used Sketch-Up to design the cabin over the winter, and have been building it from these plans.  Sketch-Up was pretty cool to use for this.  I could lay out all of the framing, and experimenting with where the windows and door would go - all without cutting a single piece of wood.  Now, while building, I can take measurements directly from the model, and it's made estimating the amount of materials I'll need very straightforward.  All the windows are ones that I salvaged last year from other peoples' remodeling projects.  You can see in the third image what my plan is for the inside.  There will be a lofted bed platform, and a window seat under it that will be wide enough to sleep on.  There will be storage under the window seat, and I'm also going to try and put a reading chair in there, and a bookcase.
