Configure your outdoor fireplace kit in 3 simple steps

Getting what you want is simple.  First, you choose your outdoor fireplace's style or shape- or Fire Spire. All our fireplace offerings are large premium kits. Second, choose whether you want a standard firebox or a see-through firebox. Don't worry. All shapes and styles of fireplace kits are the same price. You won't be penalized for having style:) Once you have chosen the "chassis" of your outdoor fireplace, customize it with add-ons and packages. The styles aren't endless, but there is more than enough to build a custom outdoor fireplace for your dream backyard.

  • Don't worry. You cant make a bad choice!

    You have found a foolproof system. All of my kits are large, premium products sold direct to you at a great price. More importantly, I only offer options that perform great and look amazing. You won't be burdened by too many options that have little value. My color blends are timeless. They fit into their natural surroundings while coordinating with your home. I keep prices the same no matter which model fireplace you choose, thereby removing cost as a deciding factor. Most important is that my kits are super simple to build. I pride myself in our easy step-by-step process for DIY enthusiasts.

    1. Choose Your Style

    Our fireplace kits start with a base model from which you can customize. Cornerstone only offers large, upscale fireplace kits. We do not hook you with a low-priced model that won't fit your needs. All our kits are designed to impress at a price that you can appreciate. The Barrington model is the most traditional. You may want to choose a Bremley fireplace for a more modern design. Both models feature the same large 28" firebox opening, as well as large hearth and built in mantel.


    For something completely new and exciting, try our contemporary Fire Spire. It is a unique blend of a fire pit and a fireplace. It combines the best of both forms in a unique tower design made to mimic old world ruins. The fire Spire is considerable more affordable than our premium fireplace kits. Any choice will be sure to be the centerpiece of your backyard gatherings.

    Fireplace for your TV

    Some people go outside to get away from technology. Some like to bring it with them. I guess is like camping vs. glamping. So we made a fireplace for all the glampers out there. Now you can watch every moment of the action whether the party is inside or out

    2. Choose between a Standard or See-Through firebox

    Your outdoor fireplace kit comes in a standard firebox or see-through firebox option. Whichever you choose, the price remains the same. You should choose your kit based on your outdoor living vision, not have many more Benjamins it will cost you. Therefore, both the Bremley and Barrington style fireplaces are available with a two-sided firebox. All fireplaces offer a built in hearth and a mantle for each firebox opening. You can learn more about our fireplace options by choosing a model below:

    3. Choose your options to create tons of configurations

    You can customize your kit and configure it for what fits your lifestyle. Add firewood storage to make your fireplace more impressive and functional. Want to make a grand statement? Need to section your patio from the rest of your yard? Perhaps you are looking to add some privacy. Our Estate seat wall option is our most functional and impressive addition. Can't decide- add both for the ultimate outdoor fireplace that will be the envy of your neighborhood.
