Looking at miniature versions of large things is our favorite pastime. We can’t help but stare in awe when we come across city layout plans that are to scale and in the form of toys inside a glass box. This homeowner, who probably has the same appreciation as us for small versions of things, made a small version of their home.
Now, the OP claimed that the miniature replica was inside its tiny library, but as you can clearly see, the replica is sitting in the home’s front yard, not inside the library. Anyway, thank you, OP, for sharing this magnificent picture with us.
