I'm trying to get a handle on the amount of room treatment pieces I need. I have some problem areas. These include an unused fireplace behind the couch, and a hollow space behind the tv that use to be a closet under the stairs. The left side of the room opens up into the dining and living room. On the right side is a large sliding glass door. I'm wondering what and how many pieces I'll need. For example, I would like to know how many pieces I'll need for the area behind the TV. Here's the link to some pictures of the room.
