We have a north facing plot and at hand will be 2 seperate floors ground plus first floor, ground floor for rental and first floor own use. In first floor we need to construct pooja room on the North eastern corner (which is proposed enterance of the house). So can we own pooja room on balcony outside the living room?
Answers:    yes, u can. But as Mr Manikandan pointed the idol should facade north or east.
in auxiliary, the place should be calm, not too squally, pleasant, comfortable to pray and meditate.
Yes you can, but see that the idols obverse North or East. All the best.
