A vertically stackable private staircase, consisting of a group of top-and-bottom stackable private staircases which belong to at least two building units. Each of the staircases in the group of private staircases which successively connects two adjacent floors comprises at least one stair flight (40) and landings (10, 20) at both sides thereof. The stair flight (40) and the landings (10, 20) are located in the same private stairwell (70). There are only private staircases and no public staircases in the stackable private staircase so that the private staircases have no association with public staircases. |
