There are also several prohibitions when using public places to increase living space. Placement of the kitchen, toilet and bathroom is strictly prohibited above residential premises. But, nevertheless, such redevelopments are possible if you take into account the requirements of SNiP (for the bathroom and toilet, the waterproofing should be very high, and there should be good ventilation in the kitchen). And if you do not take into account these requirements, you will have to return the apartment to the original type. Thus, if you take into account all the nuances during redevelopment, you can carry out many planned transformations.
