"The theater is 16' tall at the front (slab to concrete ceiling), and 11 1/2' tall at the back. About 21' wide and 29' long. This was an addition to the house - we basically dug this huge hole in our front lawn and partially into the driveway, while also gutting a study on the main floor. From the main floor, you have steps down to the basement where you see a sitting area where the marquee is and thenonto a concession area and theater. So the superstructure of the theater is a 12" to 18" complete concrete shell."
