I have an internal dog-leg stairway up to my 1980's first floor flat. It is narrow but very tall, especially on the half-landing, and there is no external light except from downstairs front door. No other additional daylight is feasible/permissable. I need decorating ideas to break up the expanse but the walls must be covered in a robust material as everyone brushes the walls in passing. I like the idea of having different materials/paint/colour for top and bottom of walls. The carpet is a light brown colour.
