When the homeowners bought their house, the builder had left them with a practically nonexistent back yard. Boulder retaining walls sat just a few feet away from the house and deck, and behind the property a gravel parking lot loomed over the house. Rebuilding the retaining walls created space for the homeowners to actually enjoy their yard. Their two energetic dogs have some space to play, and the selection of native plants welcomes birds into their back yard. As the plants mature, they will provide privacy and screening from the parking lot.
