The most impressive building was the white, adobe style house with solar panels live grass growing on the roof.

The inside of the building was three floors, with elaborate, wooden staircases, beautiful iron railing, and small windows for children to climb through.

The house was decked out with beds, a kitchen, couches, or other places for children to play.

The basement doubled as a dance studio and opened up to a nearby stream.
