I think that it looks great in this photo (except that you have to be careful to make sure the center of the sofa is under the center of the windows). However, from this photo we cannot tell if it is set back a comfortable distance from the fireplace so that you can add the chairs on the other side.

@klfische Oh, thank you for the suggestions, your post is full of useful info! I love your ideas! Just to be sure, which wall you refer to as back wall? If I understand you correctly you are suggesting something like this: I like the idea about the one big piece of art instead of many smaller. My partner wants to have concealed tv, so I am thinking about having tv mounted under the lower part of the big art, so that the art can slide up when in "tv mode".

I think if I had the luxury of new furniture, I'd do two short sofas facing each other, flanking the fireplace. The one in front of the window shouldn't be up against the wall, so that there's room for curtains to fall and the illusion of maximum space. Get a nice BIG area rug that you like, and a proportional coffee table to go between the sofas -- maybe something glass since the fireplace looks like it's dark and might just feel darker when it's competing with wood. Whatever you pick, focus on size so that there's ample room for people to walk everywhere. It'll feel generous and welcoming. Great bones!

Is that carpeting or a rug?
