What is the number of floors for a prefabricated building? Is it possible to make an add-on on the second floor after installing a one-story building?
The maximum number of floors for a prefabricated building is usually three. The maximum height is 15 meters (on the outside of the building) It is strictly forbidden to make an add-on on the second or third floor if the design loads were not initially taken into account in the process of designing a one-story building.
Any add-ons without taking into account the loads can lead to the collapse of the pre-fabricated building and fatal accidents.
