Photo from Ralf Stumpf.
If you look in the upper right quadrent of this photo you can see The Glass House. Look carefully and you can see the two stairwells. In the book Jack lives in the right one. Charlie, Sam and Jayla live in the left one. Just down from The Glass House is the cliff and then flugplatz with all the aircraft hangers, and aircraft maintenance facilities. To the far left is the Headquarters 4th Armored Division building.
I am a military brat—and I say that with great pride.
