There are some kind of door devices which push the door back after we open the door and come out.
My problem is that the door area is not constructed in a way that such a device can be installed.
There is no space adjacent to the door anywhere.
Automatic closure of door is extremely important to me.
Please see following pictures and tell what choices do I have.

There are many types of spring hinges available, though, it is impossible to tell which specific one would be compatible from here. The ones I'm familiar with look like this.
They are typically installed as a replacement for one of your existing hinges. I would first measure up the one you have and go to the hardware store to see if they have anything that would work.
Instructions on how to adjust them can be found here. (I'm not affiliated, I just found it on google).
