I currently live at 1336 Mendell Dr. University City Missouri formerlly in this city I lived 7580 Drexel Dr. While living at 7580  Dexel I took advantage of one of its unique laws ( at the time) of a homeowner could build a second story addition (and many other things ) if they could demonstrate to the inspectors that they had the ability. So I took a small two bedroom house and expanded it into a four bedroom one, so that my two ( completely opposite ) sons could grow up and reach their full potential.
