Install a 20x20 flagstone patio on flat ground behind the home. Connect the house and patio by installing a lift-and-slide glass door on the back of the house. Place a gas-powered fire pit in the center of the patio and surround it with four mid-priced all-weather deck chairs. On the far end of the patio from the home, install a stone-veneer modular kitchen unit with gas grill, mini-refrigerator, sink, and storage. From each corner of the patio, erect a 20x20 cedar pergola capable of holding an awning that can shade the entire deck. Install mid-priced, low-voltage lights on the pergola sufficient to illuminate the patio at night. Install all needed gas and electrical connections underground from the home to the patio
