Treppenhaus vs Treppe
stairs
'die Treppe' and 'das Treppenhaus' are closely related, but they are not the same. The 'Treppe' is the structure with the steps that you walk on. The 'Treppenhaus' is the whole area in the building where the stairs are located, often with doors, walls, lighting, and several floors. The words can be confused because the stairs are located in the stairwell. If you really mean the steps, say 'Treppe'. If you mean the room or area in the building, say 'Treppenhaus'.
