A spiral staircase (also known as an arched staircase) is an elegant solution in lack of space in the interior, but at the same time these stairs retain their representativeness. They can be placed on the wall and separately into the room, it is advisable if you want to have the end of the stair elsewhere than the direct staircase.
It fits both living spaces and offices. Thanks to its space-saving features, it is also ideal as a side or fire escape staircase.
