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.

I would clean up first. Especially the stuff growing in the paving. Then get gardening with pot plants and start experimenting with different plants and the positions. See what you like and if you can keep it alive! Our house has the sun setting over the back fence and we've done a few inexpensive things to reduce that issue (most expensive were outdoor blinds around the verandah) but for most of the year we just don't want to be out there. It is hard work to keep the plants going in summer, there is a lot of sand due to the difficulty in keeping lawn alive and it is just bloody hot. So, that's why I'm saying clean up, start gardening small and see how you go before committing to structures that might not address the real issues you have with the yard. Just my 2 cents! :)

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.

Here's a couple of ideas that work really well as alternatives to a walk in pantry. They integrate into your wall cabinetry, allowing you to keep central spaces open and free flowing. Using drawers to create a pantry as Esselai suggests. Check out how Harn Triomax soft close drawers are used in just this way. Availble in classic white or metallic grey. Two front to back depth options - 500mm and 5500mm. And 8 drawer width options from 450mm to 1200mm. Alternatively, there are a number of quality pull out pantry options in the German designed and made Vauth-Sagel range. Some are installed with fixed fronts to match your cabinetry, and others are installed behind hinged doors. See below (from top to bottom) the VSA model, DUSA model and HSA model. These all come in a variety of width options and specs, from chromed wire shelves to sold bases with glass panelling.
