Is the floor tile paved or the door stone beautiful?
Personally, I think it is better to add a threshold stone, which can play an embellishment role. If you don't add doorstones, the floor tiles in each room will not look good if they don't match, and even some places will not look good if they match because of their size. And some rooms may not look good together (for example, only three to five centimeters in the corner), and some materials may be wasted. After adding the door stone, each room can be freely typeset without affecting each other. I hope I can help you.
