The Double Deluxe Package is a whopper! This playhouse starts with our Deluxe Package but extends to 15 feet of pure play. A 24 inch diameter crawl tube joins both main and back house together allowing children to pass between houses easily.The back house has a 4 x 4 base with almost 6 feet of headroom so even parents have the chance to play. The best kept secret... The back house has a secret door that is hardly visible from the outside but makes for an easy escape when playing their favorite outdoor games.
