Sorry I am new to Houzz and couldn’t tell if the new photos would be viewed

What a gorgeous house! A floor plan with dimensions would be very helpful. I like the plants and the table in the bay window. The two chairs at the table aren't working; it looks like it's supposed to be a dining area but the plants took over. The chairs are also very traditional and the rest of the furniture is not. I would remove those chairs. Is there as space to rotate the sectional 90 degrees and then put the TV above or next to the fireplace? The coffee table is gorgeous but the wrong shape for the sectional. If you are keeping the sectional, get a round or elliptical coffee table instead.

These are options for you but you will have to MEASURE VERY CAREFULLY to make sure any sofa or sectional you purchase will fit. Do not purchase any seating that is very deep as there is NO ROOM for that type of furniture. You can mount your TV on a bracket to angle the screen if that works better for you

Would you be able to move the TV location at all? Maybe above the fireplace? If so rotating the couch so the back faces the dining room and then putting a couch table behind might be a good solution
