East child in W house.Where to put his bed

[myfs_150293]

Hello.
I hope someone will have the patient to read and help me as I'm kind of desperate.
My flat has the front door opening South-West (241 degrees) and facing North-East. Rectangle shape (missing small part on South corner, near the door entrance). The rectangle flat diagonal (end near the entrance, on the missing part) is closest to the N-S direction.
All of my family members are from West group except my oldest son (5.5 years) who is an East one. And we do have some troubles with him since we moved in here, 2 years ago. He's not speaking correctly for his age anymore, not paying attention, agitated, frustrated, always against everyone and everything and so on.
I must say that many times when we enter our home he instantly dislike all and starts being stubborn and agitated, refusing to do simple things we ask for like take off his shoes, undress or wash his hands.
The flat has only one bedroom and one living room. Also a kitchen and a bathroom. A balcony on NE to N. Is a very small flat with small rooms.
His favorable areas from our apartment are in the kitchen (it's right across the entrance door) and some part of our living room.
The children bedroom covers the W, NW and N according the map.
Our intention is to have both children sleep in this bedroom.
I don't know how to position my older son bed because he's favorable direction are S, N, SE and E.
How do I find the bed position for him?
1. Should I use/follow the Bagua map on the bedroom sketch?
2. Can I use bunk beds? I read that it's not a good ideea. He should be above his one year old brother.
3. Is his bed realy need to be on S,N, SE or E sector of the bedroom/flat or can I just put it anywhere in the bedroom but with his head on one favorable direction?
4. What if the wall from E, SE and S sectors of the bedrooms are either comun with the bathroom or at the window?
5. What if the N-S direction/line is not a wall line and E-W is a diagonal? Staying at the window and look outside (which by the way gives in a closed balcony) I'm watching the NE, behind is a 4.3 m/2.8 meters bedroom, on my right side is the wall comun to the bathroom that also has a window which opens in the balcony. The bedroom door is on the same wall with the comun bathroom wall. The bathroom door opens into a small hall from where we enter either the bedroom either the living room.
Therefore, if I put a (murphy) bed for him on a good direction, the feet are pointing the door and the both children beds are intersecting (which I read is not good for their relation).
Please help me as I'm confused after reading dozen of articles and files and tired of searching a solution for my older son without success.
I attached a sketch of the flat. However, the directions are not quite exactly as in reality, I repeat, the front door is 241 degrees.
So much many, many, many thanks for anyone who would like to help my family.
Have a nice and quite life.

1. This link provides some commonsense idea with regards to the concern of the bunk beds:-

2. Usually, it is best not to let the "legs" face the bedroom door as to the Chinese; this is known as the "coffin position". But, other safety aside; some place a "screen" or organizer pouch at the baby-bed panel; thus acting like a screen between the child's legs and the bedrooom door.
