Something like this may work. Note the changed door positions so that anyone in the bedrooms can visit the bathroom without disturbing anyone else in the lounge !

Invest in an architect. There are so many things to consider when designing a home, such as sun orientation, adjacent structures, existing vegetation, views (wanted and unwanted), zoning ordinances, and the list goes on. Contact a couple local architects and explain to them what you need. They may tell you that you are nuts, but at lease you will have a professional opinion.

It sounds more like a bedroom instead of a hall. If t's a bedroom, why do you need a sofa. What size is the room? How many doors and windows? Can you please show us some photos of the space, or a sketch with dimensions?

This reminds me of my kitchen in Hyderbad, India. As others said, go with open shelves. Both wood (contrast) and stainless (brightness) would work well for upper shelves. I would also do shelves in the lower cabinets. If you want to minimize cleaning, add heavy, easily washable curtains to the lower shelves. You can add some battery operated lighting so you can see into those darker spaces. As for the walls, I would use a white subway tile and go as high on the wall as you can afford. The glaze will reflect more light and the surface will be relatively able to keep clean. Paint the other walls in a high-quality white paint (use a ceramic one if you can find it, as they are a lot more durable). Keep the appliances to a minimum. Kitchen gadgets might be handy, but lost of them will make the space seem small. For the ones you do buy, go with white or stainless steel. Finally, hang pots, pans and utensils on the walls to free shelf space and get them off the counter. Make sure what you use frequently is within easy reach, while "occasional" tools can be higher up, where you might need a stool to reach them.
