Our front yard has a concrete rectangle for the center with planter box around it. We are thinking of removing the concrete and replacing it with garden soil so it would be converted into a lawn. During summer, the heat is somewhat unbearable in the terrace that is fronting the concrete garden. However, we are hesitating because our dogs are used to the concrete and they may be alienated by the grass. That concrete is their toilet for now. Part of the renovation is the redesigning the planter boxes so the decorative stones will be removed to give space to more plants. Maybe we can do this renovation early next year... if our budget permits.
