The top photos to the left are of the playhouse.  It's about 6' tall at the peak.

The bottom playhouse pic shows the enclosed stairs going up to the roof of the garage.

The middle set are of the pond.  It's an unexpected social center.  Neighbors who feel like visiting go out walking and sit down at the pond and join other neighbors or someone else.  I've looked out and seen three unrelated people who just happened to show up.   The 2x4 and the branch going into the water are both pathways to freedom for toads and lizards that fall into the pond. The 'pueblo' at one end just looks neat with water falling from it and candles lit at night.

The bottom photos are of the 'hovel.'  You've heard of tiny houses.  Well, this one is 45 square feet.  It's just a summer bedroom, really, but very pleasant -- open the door and look out under the euonymous bushes. A heating pad, and candles, work to take the chill off fall days.

          BELOW, DESIGN TIPS:

Below, pix of landscaping with the same theme that I hope to go with at Foggy Woods:  Red bricks, periwinkle, slanted angles (herringbone), wood chips, no grass, loads of evergreens, some very old bricks.  

The bottom photo shows a pot at the end of a small iffigation system -- it fills first, then dumps the water into a large saucer, and then the water runs out onto the ground.  This leaves fresh water for birds and lizards.

Water could certainly be run into a much larger pond this way, as well.
