HGTV has designs on the generation gap

HGTV is combining family dynamics with design as two twentysomething offspring enlist a couple of young designers to redo an outdated room in their parents' house. Called, oddly enough, My Parents' House, the show will air Tuesdays at 9:30 p.m. beginning April 5. Will the eccentric characters, sometimes charged family interaction and chic design transformations make for compelling viewing? HGTV is hoping both generations will tune in to find out.
