Weighing in at a mere 660 sq. ft., an updated 1920 home in Walton Court, near Airline Dr. and W. Cavalcade St., stacks a full range of roomage into its wee proportions. A $289,500 asking price was attached to the listing that appeared late last week. How’s everything arranged into the homelet? Think of its floor plan as a series of 10-ft. boxes.
