This is the stereotypical layout of each of the Casas. A casa is by no means standardized in layout but this is a fair approximation. Tricliniums are formal dining rooms.
Section 9 and section 10 has bunks for 4. Section 11 has bunks for 8. Section 12 is not present. The rooms above 2-5 have room for 4 people but is more spacious and has a bathroom shared between the four. It is normally reserved for Sophisters (upperclassmen).
