The hardscape area outside of your swimming pool and coping is known by many names, but the most common are deck, decking, and patio. Whatever term you use to describe this hardscape, it is critical that you consult with your landscape designer about material, shape, overall integration, and so on. Consider the size and scale of the hardscape elements you intend to incorporate into your landscape. Depending on the size of your yard, you may want to go with larger elements like a patio or a large retaining wall, or you may want to go with smaller elements like a retaining wall.
