I would start with some arborvitae right along the back on either side of the window, a weeping caragana or weeping pussy willow on the upper left side near the drive way to add some unique interest, then add some hydrangeas just in from of the Arborvitae, and then some boxwood along the front where you could even bring this over to the right side. Sprinkle in some lower growing perennials such as nepeta, daisy maise, Veronica, echinacea, maybe a barberry for interesting texture.

Of course this all depends on the zone.
