Life is change
During construction, there may be changes to the design documentation that gave you a building permit or a construction announcement. These changes are necessary before the building approval (by the notice of use) of the building can be entered into the project of the house and submitted to the relevant building office. The changes you have made will be incorporated into the documentation to match the actual state of the construction and a successful completion of the building approval of the family house.
The changes you have made will be included in the documentation in the price of CZK 1,990
