If this were my house, I'd remove the painted cement block, revise the walkway behind it so that it is farther out into the lawn (either curved or simply relocated) to allow construction of something to cover most of that wall under the windows. It would have to be multi level, maybe even multi materials, but could be done. Taller with evergreen vine or shrub on that part and maybe plain on the parts under the windows. Or I might move the walkway out close to the street and eliminate the lawn altogether, build something to disguise the utilities and plant multi layer landscape to take the focus off this side of the house.
