1. Would an addition built on to the back of a house 30 years after the house was built be included in the main blueprint?
2. Or, should this addition be treated as a separate strucute, as it was not built in the same ruling star?
3. Or should the central palace for the home be determined based on the original houe and the direction (in this case SE extend out to incluede the addition.

Your aswer would be greatly appreciated.
