Here're some grabbed quick off a fine designers' website that aren't templates for this room but do illustrate the idea of loosening up furniture placement for living and inviting people in. There's no rule about facing a sofa to a fireplace or not, placing something diagonally or not, just as there's no rule that furniture must be placed at rigid right angles and not allowed to be angled or moved over for better conversation. These designers charge a lot to mess furniture placement up like this. David Easton's, second below, could look as if it were going to be formal right-angle but some of the chairs aren't placed yet--but it doesn't. This designer knows how to arrange furniture for comfort AND elegance, without static rigidity. Note that none of these arrangements present their backs or a cold shoulder to guests in the doorway. They draw people in. Not all pictures clearly illustrate that, but the designers' stature guarantee it is the case. Also note all these arrangements include a lightweight chair or two, or more, that could be moved closer in or over for a really good coze.

@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 like the 3 stylish ladies for your bedroom. Can't see much about the rest of the art and furniture. Making a guess that the slipcovered sofa is too far gone to keep. Do I see two of the chairs and footstools? They look a bit under-scale for the brown sofa. CraigsList is often a good place to get rid of the overflow and make a bit of money to invest in new pieces. Those chairs (or one of them) might do well for seating in the master bedroom. I think the brown sofa is in the right location. Center it on that wall so guests will be welcomed into the room by it. I would get a piece of art 75% as wide as the sofa to hang 5" above it. Your end table is too tall and not the right style. I'd replace it with a pair of tables and lamps to complete that wall's vignette. Then pick up a coffee table to place 18" or less from the sofa. Then let's see how much space remains. Is TV in the cabinet? If so, that should probably go opposite the sofa. How many do you need to seat in this room? Here's a chart for getting the table and lamp heights right.

Corner windows are nice. Embrace. is this a, quiet visit room or a tv room? How many seats do you need? Embrace the window by putting chairs perpendicular to each other with a table in the corner to enjoy the view. If there will be a tv, let it be on your door wall so you don't see it when you walk in. That would allow 2 sofas L'd or a sectional. Many options in this room. Just don't dis the corner window. 😎
