I like the warm colors in this picture, but if it were my room, I'd put a more comfortable chair in front of the fire.
This one looks 1) really old and 2) like it would heat the whole kitchen. I think I would be tempted to make s'mores.
This one looks like a bakery. Imagine snow outside the window instead of leafy, summary greens.
Newer houses don't often have fireplaces in the kitchen (at least, not the ones I've seen on Trulia and in other listings.) I wonder why.
But, at first glance, this kitchen below looks like it might have a fireplace in it. It definitely looks warm. Maybe it's the antlers hanging over the range?
Here's another picture of a kitchen/dining room that looks like it might have a fireplace in it (and I don't know, maybe this room does have one on the other side of the table). In this case, it's the slipcovered arm chairs that make me think of fires and other warm thoughts.
