I have a floorplan that has a second floor that is half of the size of the first. I am confused with the layout of the stars because if you look at an apartment and how you would judge the space on the area occupied, then the layout would get smaller like a tai ji instead of just brought up from the first floor losing some of the palaces in the process. Any thoughts? Also, for an apartment, is the door direction considered the apartment facing direction or the main door to the building? Thank you,
