For a house with a courtyard, is geomantic omen based on the courtyard door or the floor door?

The courtyard gate shall prevail, because it is the main air inlet. All the qi of birth and death enters through the courtyard gate. The courtyard is a whole with the outside world, and the gate is the air intake. Even the direction is based on the gate of the yard. The door of the building is just the entrance door or the middle door.
