Hey yall! So I need help chosing what to add to my hallway. The radiator and the windows make this very hard, the radiator will get hidden by something made from wood but I'm not sure what furniture to add because I don't want to let the space empty. The upper portion is 2.5m x 50cm Any ideas are appreciated <3 I also attached a photo

custom shelves that taper at each end so not to interfere with the windows?
maybe a little storage unit under each window facing towards each other and a cushioned seat on top?
