It is known that seismic activity in Armenia occasionally exceeds the normal limits. In spite of the fact, many houses here are built without observing essential construction standards. In the event of an earthquake, many of them will be easily demolished falling onto each other.
There is a saying according to which every Armenian must plant a tree, raise a son and attach a house to his apartment in Yerevan.
The 5-storey houses that used to look neat and nice in Soviet times resemble now the Shanghainese slums.
Unauthorized construction is progressing rapidly and hampers movement. Houses are totally hidden behind adjacent accommodations.
People add new floors to the roofs and new rooms to the houses they live in.
Free space in the yards is occupied by garages and numerous buildings used for different purposes.
Due to unauthorized construction the size of the building can be increased twice.
The building itself can be totally closed with new utility rooms.
