Some shrubbery and flower beds could easily hide it. It looks relatively new, so many just not done yet. Or better yet, the neighbors volunteer to help the family install said plantings.
It looks they've already put in a planter bed with small plants - takes time to grow, but will provide cover up the cement wall -
so it looks like these people have spent a LOT of money having a professional ramp build and have put in plants. What more do these stupid neighbors want?
