Looks like they did a similar thing here with a false ceiling. These look a bit more built in as well.

I love the color you have on the wall by the patio doors. I'd go with that all over if you want the space to feel warm. Or, if you want the rooms to feel cooler, you may want to go with sky blue or a calm green. The right shade of green brings in your outdoor plants, which looks very nice when you are looking out through the windows. Your flooring would look fine with any of these choices. Grey is another color to consider. I personally do not like it, yet is is quite popular now, especially with contemporary interiors.

I would suggest you take out the cabinet that is to the right of the stove and use it elsewhere in the house -- perhaps in the bathroom or dining room with a hutch above it. Then, I would suggest you have someone install a lazy susan cabinet in the corner between the sink counter and the stove, meaning you would move the stove down a bit and have a small cabinet/counter top to the right of the stove. I would suggest you have the cabinets refinished in white and then paint the walls a pastel you like. If you would prefer white walls, then add white-painted crown molding and paint the ceiling a light neutral blue, such as Sherwin Williams Niagara Falls Blue. Then, I would suggest you choose a favorite accent color and use this sparingly in accessories like towels, pot holders, small vases or floral arrangements, and a valence above the triple windows. For a genuine 1940s look, you might have white ceramic square tiles with a rectangular red border installed as a back splash behind and above the stove. If you are replacing counter tops, I would suggest a light color such as white with a beige or light grey vein or striation for some sort of pattern. You might be able to find the same color and design in floor tile OR opt for a wood floor as another poster suggested.

Does this represent what the kitchen designer is suggesting?? If you stick with this design, I don't think you should place french doors by the table, as there is no clearance. Also, does your laundry have to be in the kitchen?
