Less is more!
Less is more is the best explanation of minimalist style. There should be less of everything, so that it can look good. So, if you plan on having a seating area in your backyard, you should again keep it simple. Opt for some plain and well defined design in some neutral color. And in terms of plants, you can never be wrong with boxwood. The evergreen foliage will give a year-round monochromatic color to your backyard.
So, would you choose to decorate your backyard with the minimalist style too?
