This is a combination library I've come up with.  The three of them once screwed together are just over 48".  That's a lot of library! It's a combination of two Smaller  Libraries and a Townhouse Library.
 
The standard configuration will be one shelf in the Townhouse and the smaller libraries won't have any. The shelf is removable if you'd like to take it out or put it back in. You also have the option to upgrade to wood or asphalt shingles in the pull down menu.
 
This will ship in 2 boxes and the libraries will need to be screwed together.  Don't worry, I send the screws.  This setup will require a standard "Y" post. The library will be heavy!  I'll also be sending a board for the libraries to sit on for stability.
