GreenHeart LLC's principal, Cathy Carr, designed this transformation. The steep hill in the backyard of this townhouse was transformed into a more walkable and dog-friendly space. Irregular flagstone forms the patio and Colonial Steppers rise to the back gate. Large boulders are stacked to create retaining walls that level the terrain for easy-care plantings. Great American Landscapes installed the patio, boulders, and plantings while SDF Builders constructed the new back deck and foyer.
