There are places in all homes that offer a 'gallery' space. Corridors or the hallway are an obvious choice, though sometimes overlooked because of lighting.  The size of artwork displayed depends on the width of the corridor, how far you can stand back. The options you have here are endless -  art 
photography or 
printwork can be just as exciting as traditional artwork. 
Landscapes, 
portraiture  or 
abstract artworks can all be displayed in your hallway, depending on your own personal preference.
