Be, there should not

The main difference in these apartments is that you can create your own planning of apartments. In these apartments, most often, the apartment is fully adjusted to the owner, that is, the owner can plan anything, while breaking the rooms with ordinary partitions. If you decide to redraw your apartment, then you will have to follow certain rules. An example here may be, there should not be more rooms in the apartment than windows. But even such a restriction does not stop the residents of the apartments, and they use their complete imagination.
