Any backyard- Add a pergola separately, but with style to add height. Plant some beautiful vines to cover as much or little as you want for added privacy in your backyard. Great for those with second story homes surrounding them.
DIY - Homemade Gabion wall ie rocks encased in wire baskets and used as a retaining wall - creates a dramatic feature in a garden. No directions on link. Nice someone figured out how to landscape with river rock. I swear they grow!
