The attachment at the wall is hidden behind the plaster - simple and elegant. As much as I like this design, I still want to avoid the cold touch of metal. Wood seems to be the logical response to this concern, but wood brackets would lack the strength and elegance of this metal solution.
My solution would need a hard close-grained wood that is smooth and warm to the touch. The bracket would be metal with a shape and elegance like this one. Stay tuned as I explore the world of handrails.
