The apartment I live in has this huge L-shaped hallway without any windows (luckily some of the doors along it have glass). The first part is also the entrance and it's more or less 2 x 4m. The other part is about 8 x 1m and one side is divided in 3 by columns (no doors on this side). The walls are painted in white and the doors and the floor are dark brown. I need to decorate this space somehow. One idea was to use 2 rows of b&w photos for the longer part of it, but I don't really know how to make the passing from one part of the hallway to the other.
