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.

There are some great comment here, but my take on this would be if you are going custom to take your time and look around. Many designers offer different takes on each person's preference. The colours you have are good but I'd personally would opt for a more warmer cream, with a self print pattern. I would also suggest pinch pleated curtains and not pencil pleat as you have currently, pinch pleated curtains will give you uniformed pleats from top to bottom. In addition to this I would suggest you use blackout linen to prevent light to enter the room, and possibly interlining so that you retain some thermal properties in your fixtures. Having custom made curtains are a lifetime choice for most customers, take your time and don't settle for the first company you come across. The space above your bed i would possibly add a sheer fabric roman blind which is slightly see through but enough to give you privacy if you bedroom is situated on the ground floor. You can also get the a roman blind to match your new curtains if you'd like a more repetitive theme in your bedroom. I would suggest if you do opt for a roman blind, and you are looking for a good qualities add blackout linen.

Have you tried looking through the Houzz professional's tag or asking the people who have posted the photos that you've seen where they got their cabinet from?

Possible suggestions if sticking to same floor plan and hands firmly glued to the budget Leave the stove where it is. Down the side of the stove securely attach slimline fireproof panelling to the height of the oven's back control panel and the depth of the oven. Floor to ceiling if you prefer then if you wanted to you could change out the door itself, that is put the door handle to the right of the door so it swings back flush with the fireproof panelling. Put the dishwasher under the stainless steel bench top left of the sink. Take all the cabinetry out where the dishwasher is currently housed place the fridge in the centre of that wall building functional cabinetry around it. Get rid of the cupboard at the end of the stainless steel bench replace it with a wheeled butchers block the same width and depth of bench also have hinged sides so you can get extra useable bench top surfacing. You could then wheel it around include brakes on it of course so little hands don't go racing around with it.
