I just moved to an apartment building for the next three months. The door to the apt is in a hallway. that side of the apt has no windows. The unit is a perfect square. All of the windows are on the opposite side, so when you go into the apt you see them in the back and they overlook a street. Based on this, I have come to the conclusion that the facing is the side where the windows are and sitting where the door is. It is a double facing building and has a year lock for finances. I understand I have to add mountain and water to the facing (5% of the sq. ft) as exterior remedies right? but where would I put them and what alternatives do I have? there is no balcony., just a wall with three windows. Thank you for your help .
