Many homes in Thailand have a spirit house on the property. Moving or erecting a spirit house requires the services of a priest, usually a Brahman, or sometimes a Buddhist monk. The priest consults horoscopes to calculate the time and day of the erection ceremony, and the color and placement of the spirit house.
There are many rules about where a spirit house should and shouldn't go, and getting it right is very important. The spirit house on the Red Bicycle property was in the shade and on the left side of the door. This broke two of the rules so the priest asked us to move it to a sunny area on the right side of the door.
