This feng shui layout is generally only applicable to indoor and living room parts.
Generally, after entering the door and passing through the porch, it is the living room, and the living room sinks, so that the feng shui in the high places in the room will not flow out.
Generally speaking, this layout is a split-level building or a split-level villa.
When it is applied to villas, it is generally suitable for situations where there is a big difference between negative zero and outside, the floors in the house are high and there is no basement. Or in the case of semi-basement, there is no need for a building with a complete basement structure.
