Suggestions for Living Room
So, do you want to watch t.v. look out the window or the fireplace, you said chimney is there a fireplace? Is that a wall or a counter area on the kitchen side? If the space is large enough you can have a sitting/reading area by the window or fireplace area. Typically you would create a conversation area, couch and chairs, coffee table. With long spaces people tend to push things up to walls and stretch it out, ick. Will your t.v. be wall mounted or on a stand? Tell me these things or take a pic and I will show you some layouts.
