Everyone needs a hobby, and one of mine is building cardboard buildings. My recent endeavor was to build a complete modern day urban city for the game Mechwarrior: Age of Destruction. Here are a few photos of the progress of many hours of designing, printing spraying, folding, and cutting.
This a general overview of the city. All the buildings are made out of cardboard (cereal box weight material) with paper glued to the outside. The images are building found online, and some that I created myself using templates found online. All the buildings are approx. "N" Scale for you train buffs out there. After cutting and pasting, the corners are scored with an Exacto knife to ease the folding.

While many of the buildings are simple rectangles, some have multiple folds. The church on the left of this picture of nearly 20 pieces of cardboard folded in multiple directions. To make it even more fun, it was found on an all Korean site with no English instructions.

One of the tasks in creating a city is not only to make it to scale and unique, but to also make it usable for the rules of the game. That means some buildings need a flat roof to be usable, others need doors, others may need to fit into certain size specifications. It also means that there needs to be certain spacing between buildings.
Some future developments may be several communications towers, an overpass, and maybe another church.
I hope you have enjoyed the tour of my city!
