Hi - Congratulations! It looks like you've got a great view out to your garden, too! Very nice!

I like the two-sofas facing each other. If you're going to replace them, get two of the same sofas, and the same size. Then I would place two chairs facing the fireplace. Something like this rendering I did for a client.

For your fireplace, I actually think the rock looks good on the surround. Above the mantle, I might consider removing it, and just have some drywall there, painted to match the rest of the walls. You could do some shiplap (horizontally) right over the rock above the mantle, and white wash it, if you like that farmhouse feel.

Another way to arrange the seating is with one sofa facing the fireplace, and placing something like a console table or narrow credenza behind it. It's a great way to display flowers, and you could place a couple of lamps on it. It acts as an entry table.

You have several options: Two sofas facing each other with two chairs facing the fireplace, as shown above, or one sofa facing the fireplace with two sets of two chairs on each side, facing each other, or two sofas in an L configuration, with one facing the kitchen and one facing the fireplace, with two chairs with their backs to the kitchen. Make sure you leave room for end tables. Don't feel like you need to fill all the spaces. Once you have your seating in place, add some artwork. Then you may only need the credenza or a console table against the wall as you have it, and the piano, with the rest of the room empty.

Congrats! The house is beautiful with so many options. On the large empty wall, I would do an architectural element like a board and batten , to create interest on the wall. Add a very long credenza on that wall also. For the seating you can either, do a large semi circular sofa facing the fireplace, which would make quite a statement. Or you can do facing matching sofas flanking the fireplace with a bench between them facing the fireplace. Either way, you have a lot of options with such a big beautiful space,

Maybe if we share some images of our designs with you, that will help you with your layout and furniture options.

Wow, thanks for all these ideas! I hadn't thought about getting two matching couches, but that would look great in here. A semi-circular couch would be a gorgeous statement piece too. These photos really help to get a vision of the room (love that little pink sofa!)

I'm also liking this look with a sectional and couch, although I'd probably want some brighter colors in here:
