  • Method for modernizing a building and structure with an elevator system constructed in a building
    Patent number: 10577808
    Abstract: In a method for modernizing a building, a former stairwell of the building is converted such that an elevator shaft of an elevator system to be constructed can be provided in the former stairwell. The elevator shaft is provided in the former stairwell of the building such that stepless access is facilitated to specific floors of the building from an elevator car of the elevator system, which car can be provided in the elevator shaft. A new staircase is constructed outside the former stairwell. In addition, a former staircase is removed from the former stairwell. Furthermore, access bridges are disposed next to the elevator shaft in the former stairwell, thereby enabling flush access from the new staircase to the specific floors.
