Generally, a bagua extension will take less than half of the bagua area in which it is located. For example, your extension may take less than half of the Children/Creativity area, or the Fame area.
Bagua extensions are considered auspicious in feng shui as they bring additional energy to the feng shui bagua area in which they are located.
