Don't forget the door

I started to build a dock, which then started to become a little fort. I scratched it and started to build a marina in my old style with blue and white gradients. I set it up in a fashion of 5mx5m modules. Once I finished one section, I was able to copy it to another part of the building. Some modules were able to use existing ones and modify a corner or extend the floor. In all my fun, I forgot to build a door, and am now trapped within my home. Well, how hard can it be to build a door? From Dedric Mauriac via bloghud.com
