Above, you can see the same, where the hinges are located. Below, you can see how it opens inward. Once I paint it green, and put in some weatherstripping (also painted green), in the seem, it will look pretty seamless, like a fully round door when closed.
The next step is to frame in the left side and install a ball latch, so the door will shut and stay shut. Then I will prime it, paint it, and put on a brass doorknob in the middle. Then I will build out from there to create a door jamb, and a recessed look to the door.
With this much of the door completed, the kids excitement about the project more than doubled. The door, I guess, even unfinished, makes it seem that much more real to them. Since I built this, they have slept out in the hobbit-hole in their sleeping bags 5 times (in less than 2 weeks).
