The proposed design (it can be called a two-storey stool, stool-ladder) is very practical, simple to manufacture and may find use in the summer house and in the apartment.
Wood sheathing. Such way of furnish of walls in recent years is becoming more common. The most preferred veneer tongue-and-groove boards.

Particular care should be fixed to support bars in the areas of the corners of the walls. The distance between the bars depends on the thickness of boards: plating thickness 10 mm are typically used to cover walls for supporting bars, spaced at 400-600 mm. Sheathing of boards of greater thickness (12 mm) recommended for surfaces separate elements and must be sufficiently rigid when the distance between the supporting bars of 500-600 mm.
