Recipe for success!
This may sound simple, but often an view has to be created or space made in order to take advantage of focalization. I like a 4′ bench in most courtyard gardens since it is a diminutive size that can make an impact easily. Two people can just fit! The garden pictured is one I designed in Charleston, SC on Murray Boulevard. The 4′ bench is used as a focal point with carefully scaled plantings, including boxwoods to anchor the setting.
