FALUN, Sweden (AP) _ A grandfather in central Sweden used 809 empty milk cartons to build a playhouse for his two grandchildren, the national news agency TT reported Wednesday.

The children's mother, Birgitta Jansson, told TT that her father Gunnar spent the winter gathering, cleaning and gluing the quart-size cartons into a playhouse.

The house was reported to be ''cool and comfortable'' in the 80 degree sunny weather.
