Perhaps one of the most unusual, yet stylish bookcases I've come across are the Eclectic Interiors Pipe Shelves.
Normally when you see an exposed pipe it is a big no-no. It's not a sight you want to see and it can affect design plans greatly. With Eclectic Interiors Pipe Shelves, homeowners won't mind showing off a little bit of grittiness. These pipes will hold your literary favorites in one place and it comes in different styles as well. Normally an item such as this requires assembly, but the good folks from Eclectic Interiors will have it shipped and ready for you to mount on the wall. I guess exposed pipes at home aren't so bad after all.
