1, the ventilation effect of the left-hand room entering the door may be poor.
2. The partition of the balcony part should be a sliding door.
As for lighting, since yours is on the first floor, but the distance between buildings is unknown, it is recommended to have a look at the real room.
The lower floors of some buildings will affect the lighting, so don't just listen to the sales people saying nothing. Moreover, huxing is on the one hand (except for the load-bearing wall, you can generally find a decoration company to change it according to your own requirements), and the rest should also consider the supporting facilities around the community, such as primary schools, hospitals, transportation facilities, community property management, community greening, whether there is an underground parking garage and so on.
As for Feng Shui, I don't know much about it. Because I don't believe it myself!
Finally, I wish you a happy life!
