What would you do with a massive concrete house in which most of the plumbing fixtures and cabinets have been removed? Built 15 years ago as a modernistic showcase for more than $ 3 million, the 21,000-square-foot house sits vacant next to an old cemetery in the middle of an 18-acre field. Auto dealer Dan Pfeiffer bought the house out of foreclosure for $ 410,000 several years ago.
