Huxing design, please help.

Have you ever seen Feng Shui? The living room is still in its original position. Do you think it is reasonable to go up the stairs and take the 10m corridor to the living room? Four bedrooms and one bathroom are obviously not enough. It is recommended to have multiple bathrooms. Now the bathroom in the picture is inseparable from dry and wet, with a total area of *** 130 square meters. Do you want to get a living room of 30 square meters, because four rooms are already a little compact? Can't find a decoration company?
