A three story climbing wall built into the stairwell

Who wants to hit the wilderness for rock climbing when you have your own facility at home? The stairwell has been converted into a rock face of moderate height making it ideal for children to learn the basics of rock climbing. The height is also safe and the pulley and ropes attached to the rugged rocks ensure safety. The teenager, who obviously has an interest in outdoor sports, is seen trying to scale the rock and the look of determination on her face says she is definitely going to make it. Surely a grand way of using up your stairwell space.
