12. "Rect Cavern" Traditional cylindrical experimental hall turned into a rectangular solid box of semi-realistic dimensions (no vaulting of the end wall). 13. "Paint 2mm 20% B" Like above, but with these self-same flat walls painted with 2 mm of borated concrete (20% boron by weight). This is probably near the thickness and boron content limit achievable by "painting", "stuccoing", or "gunniting".
