If you are not satisfied with the location of the premises in your apartment and you decided to change everything, then you have a grandiose redevelopment. It should be remembered that any change in the layout of the apartment, different from the BTI plan, will be a redevelopment.
The redevelopment itself is not only the construction of some new partitions, but also the demolition of the old partitions. If you decide to demolish at least part of the wall, then in addition to the resolution of special bodies to this, you will need the help of specialists who will make this redevelopment for you, and who should not only have high qualifications for these work, but also a special license and permission On them. This is necessary, because often the redevelopment itself can affect important house systems, such as water supply, ventilation.
Any redevelopment should be coordinated before starting. But in reality, everything is done the other way around.
First of all, you are preparing the project of the upcoming redevelopment itself. First prepare it yourself, see what and where exactly you want to change, decide whether you need to demolish any wall, check whether it is a carrier. You can determine the supporting wall yourself. Because if the wall thickness is more than 12 cm, then it is supporting. You also need to take into account the floor on which your apartment is located. Since it is more dangerous to demolish the carrier wall on the ground floor than on the last. Think over again, weigh everything “for” and “against”.
If you still decide to redevelop the apartment, then for starters, check the plan of the apartment with the BTI passport. It may turn out that some redevelopment already had a place to be. Then you need to get a technical conclusion about the possible redevelopment in the apartment. And on the basis of this conclusion, a project of redevelopment itself is already drawn up. And with this project, the coordination of your redevelopment is already beginning. But with the introduction of the “one window” system, this process was quite simplified.
You can start redevelopment work yourself only after receiving permission on them, and then not earlier than a certain time.
