"my kitchen faces north, and I have 7'x3' windows above a wall of base cabinets. I would avoid designing a home with the kitchen on the south due to the direct sun and glare it can produce (also why I never put art rooms on the south on school designs). North light gives great general illumination to spaces. On an overcast day, this window provides plenty of lighting in the kitchen during the day where no lights are required. Also against the masses and general recommendation to lighting, I also never put can lights in kitchens (or use them at all in general where there is an insulated ceiling above). They are energy leaking pigs, and the lighting they product is spots. It highlights your head and casts shadows onto your work surface. it is not good task lighting. In the kitchen you want general illumination of the space and then task lighting on your tasks, not your head. general illumination is achieved with indirect lighting, and I typically use 2 rows of T5 fixtures above the cabinets, pointing out into the space at an angle with a semi gloss painted ceiling finish. Task lighting is handled with under cabinet lighting, Again, I use T5 not LED bc I do not like the spotting LEDs give off. I then use pendant lighting mounted roughly 6'-6 4' to it stays above your head and shines light down on the your hands typically out of the glare angle for your eyes. What you are left with is an energy efficient space, with great lighting and no shadowing in the kitchen."
