250 cm default wall height + 12 cm default floor thickness). The height of staircases in furniture libraries is set in such a way that the elevation of their last step is at 262 cm, which matches the default elevation of upper floors in Sweet Home 3D (i.e. Levels viewed with Display all levels option selected In case you find more convenient to see all levels in the 3D view and not only the selected level (and the ones below it), select the 3D view > Display all levels menu item. Note also that your staircase is visible on both levels in the plan, because its height goes beyond the elevation of the second level. Available levels appear in the tab list shown at the top of the 2D plan, and clicking on these tabs lets you switch between them. Once you add a level with the Plan > Add level menu item, the staircase will automatically make a hole in the ceiling, showing the sky through it until you build and decorate the upper level. For example, the following screen capture shows how appears a staircase in a home with only one level: the staircase doesn’t make any hole in the ceiling. The staircases available in furniture libraries, as well as the ones you import with the furniture import wizard when the Staircase option is selected, will make a hole in the ceiling of a room only if there's an upper level. This is a good opportunity to explain how to use staircases in Sweet Home 3D and the new Invisible material option added in the version 5.2.

You may have noticed that the Contributions furniture library 1.6 released in February 2016 contains many new staircases.
