Tardis

I'm new to blueprints but I wanted to build this for my daughter. I tried building on a corner but the signs got cut off since they were out bounds. So I randomly built in the middle not realizing that it would mess with placement. Boy was that confusing the first time I tried to build it.

When I line it up on a square, it actually builds one to the left and two back (or up) from where I aligned.
