Need some help filling in this corner in the hallway, right at the end leading to the bedroom (see pics). The wall in the top photo (with the red fire switch) is 46 inches at its base, and the wall in the second photo (adjacent to bedroom) is 44 inches at its base. There is a 4 inch clearance between the doorframe and the wall. Our style is minimalist and "airy", and we like lots of bright color (don't want anything too bulky or traditional). Thanks in advance!
