It’s not an open plan kitchen/diner or kitchen/living room - it is literally just a decent-sized but not massive kitchen. My family are protesting that sofas just don’t go in the kitchen but I think a little sofa and maybe a small coffee table in the corner would be a nice place to sit. Morning coffee, somewhere comfy for guests/family when someone is cooking and more out of the way than someone sitting at the island while it is covered in food prep etc. What about a rug? Do people have those in the kitchen? Again, my family say no but it would be way across the room from the cooking area.
