The distribution of interior space is also based on strict principles of symmetry in reference to the transversal axis of the building. The most common disposition is that of double (eventually triple or even quardruple) elongated rows of rooms with an addition at the end of short lateral rooms, perpendicular to the others, whenever these is a door opening on the lateral façade (an arrangement which, it is true, is common to many Maya buildings without massive towers).
Depending on the length of the building, there are one or three doors in the main façade, while the rear façade--which can have two and, exceptionally, four doors--frequently has none, displays plain sections, admirable executed. This is precisely one of the great qualities of Yucatan architecture: the profuse usage of wide, smooth lower wall zones that can extend from one end to the other, outlined only by neat moldings which accentuate the principal horizontal divisions of the building.
