Some further refinements of the cave design structures. There are two possible routes for construction. The “Ideal” design has both crew caves as well as enclosed passages leading to those caves. The “Stripped-down Design” is a fall-back plan which uses less materials and can be built in less time.
Here are SketchUp Models for the two designs. You can look around and even move things about it you would like to try out some alternate designs. Please note that the models have not been skinned with craft paper. These are the frame outlines of the strctures. In the “Ideal” design, I’ve drawn a yellow path on the floor to show entrances.
