The outer wall, especially in the region of staircase, is opened by several vertical and horizontal separating cuts over entire height and width for the lift shaft. The outer wall section, within the cuts, is removed. Prefabricated parts (10,20) are inserted into formed wall aperture floor by floor. Each prefabricated part contains an outer peripheral profile frame (12), horizontally connected to building structure, and vertically to further prefabricated part, or structure. A lift shaft is coupled to outer wall in region of prefabricated parts. Independent claims are included for prefabricated parts and lift shaft. |
