Playhouse?

For the last two summers, one of my neighbors has been doing landscaping in her backyard, shoring up a stone fence that had been built long ago by her father, removing excess brush, developing a curved gravel path, planting new foilage, and building this "playhouse." I'm not quite sure how she plans to use it or what might be its main purpose, but it's been fun seeing the attention she gives it. Next time I see her in the yard, I intend to go over, visit, and take more photos of her "playhouse."
