The most common opening in rock rooms is the zenithal type, at the top of a pyramidal ceiling. Light and air factors and dependence on buildings above ground set the limit of penetration onto the rock and affect the layout of rock environments.
As for the distribution of spaces, Kipsidze relates that in units with three or more rooms, the smaller ones, like cells, are lined up alongside the large room. A second criterion is the aggregation of square rooms along the axis of penetration in to the rock; ventilation on this case is ensured by the entrance and zenithal and opening of the first space.
