How to make alterations to flat

To make an accommodation more comfortable people make alterations.  But no alterations should be made individually. 

First, you can inflict harm to vital constructions and run into danger of walls or even the whole house collapse. Secondly, illegal and unregistered alterations can negatively affect the attempts to sell a flat, and also might cause difficulties upon execution of all notarial transactions.

Important! The procedure for formalizing alterations to the layout of premises depends on the nature of the planned work. If the changes do not affect load-bearing or external enclosing structures, engineering systems or equipment, and do not change the functional purpose of the premises, a simplified procedure applies. If such structures or systems are affected, it is necessary to obtain the initial documentation and complete the design and approval procedures required by law.
