What image does the term “fixer-upper” conjure? Maybe a shabby but charming house, needing only a fresh coat of paint and a dab of landscaping? Or what about a house that needs a bath and kitchen makeover?

To Rob Brent, Jane Murdock, and Jason Riggs, it means those things and a whole lot more. It means extreme renovation in the form of removing a storm-damaged second floor, installing a roof where there was none, and even towing a house five blocks from one location to another to prevent its demolition.
