What is to the right of the fireplace?

I would think that placing the sofa perpendicular to the fireplace facing out the large lovely window with its back forming a sort of entry corridor / maybe with a sofa table there for laydown and putting the wing chairs across at the window itself would be a good place to start - seems there would be room to walk into the space on either side of the sofa that way - and that anyone on the sofa would have a great view. You have lots of flexibility and great views it seems. How will you use the space?

Thank you, that is a great idea! An entrance to the kitchen and hall to bedrooms is to the right.

Many options are open for this space. You can flank the FP with the wing chairs and put the sofa in front of it. The sofa can go perpendicular to the FP with the wing chairs opposite the sofa sharing the same area rug. In warm weather you can put the sofa at the window with the wing chairs facing each other over a coffee table, and you might like at least one side table to use with the wings when they are paired. Additional furniture might include some pieces for the two walls at the entry - perhaps a credenza and a bookcase or secretary as the present owner has. Where the present owner has mirrors I'd prefer art.
