Please, please, please help; following the guidelines here draw the basic shape and the construction stages of your choice of the original buildings (preferably start with temperate to get one climate done and out of the way). The graphics should capture the architecture of the original building but can vary significantly from the original so long as the building use is still obvious. I will then texture the buildings and create their base tiles.
Attached are the modern office block and a quickly textured version to show what I mean... (I will do the texturing better than this for the real thing

I had a lot of difficulty trying to make them not regular and failed...but they're awfully straight and neat...
