I have a room on my second floor, currently there are only 3 walls, soon to be two when i take the wall next to the stairs out. Because this room will be open somewhat the first floor, i wanted to make some sort of den or library. I'm looking for plans to make a bookcase for the wall, something you might see in a wealthy home i.e., a library. So far I have found nothing but 3-4 shelf book cases, i'd like something that's about 10-12 feet long and about 5-6 feet high. I don't mind if i have to build 2 seperate units then place them together. Help please.
