Inexpensive DIY kits make building your outdoor living patio fun and easy


Creating an amazing outdoor living space does NOT have to be difficult. After spending hours looking at backyard patio ideas, you are excited to start planning your own. Then the reality sets in. This can take lots of time and money. There are so many unknowns and so many products to choose from. You begin to get overwhelmed or even suffer from choice overload and analysis paralysis. Well, you no longer need to worry. We are here to help. Cornerstone has assembled a dream team of installers, manufacturers, vendors, and designers to cut through the haze and bring you outdoor living features that are simple to build and simply work.

Too often, people underestimate what it takes to successfully install a functional, cohesive outdoor vision. Many times, people have an idea, but don’t know how to communicate it. Moreover, that can’t execute the vision. Even organized people that can make decisions don’t know what they are missing, what components work together, and what they don’t know. We are here to toss those headaches aside. Whether you plan to install your dream patio yourself (DIY), or have someone else install it for you, our kits will save you time and money. You will also know exactly what to expect from the finished product.
