I would like to have display/storage space at my living hall. This wall is about 12.5' wide, 15' tall. Tried to fit a cabinet there, but it seems rather odd cause it looks pretty "short" and incomplete compared to the wall.

15' cabinet is going to be rather costly and I need a tall ladder to get to the top like harry potter library. Wanted the cabinet to be display/feature cabinet... also thinking if I should just partition all the way to the top.

Thank you very much in advance!
