DIY Outdoor Fireplaces kits come with these Features

Your fireplace kit has been designed up to a standard of excellence and safety. We don’t design down to a price point. From heavy angle irons, deep mantels and hearths, and stone appearance, see what is included in our kits that other companies skimp on or charge more for.


Stainless Steel Spark Arrestor

Stainless Steel Spark Arrestor

Your safety is our top priority. Therefore, we include a spark arrestor with every kit. This addition will help prevent wildfires. It is much safer than a 100-plus pound stone found on other kits.

Large Mantel

Can you believe some brands charge over a thousand bucks for a hearth! Of course, our hearth comes included. Per best practices, we design all our fireplaces with a 14-16″ hearth for safety.

Firebrick Lined Firebox

Our wide firebox dimensions help produce great draft and heating efficiency. The opening is wide to allow ample room for your fire while not being overly wide and inefficient. Fire brick lined for heat retention and longevity.

Easy to Build

Our Fireplace kits designed to be assembled in a few hours using our unique building system. The pieces are relatively small, and the instructions are simple to follow. You simply stack and glue the pieces together. No cutting blocks. No mixing mortar. No mess.

Our kits are easy to build for beginners with no heavy lifting

We have a unique building system


Designed to make kits easily

These blocks were specially designed to make hardscape features. These are not repurposed retaining wall blocks. This produces easy-to-make kits that save time. The wedge shapes help increase bonding ability for a solid product that is built to last.

Random stone look

Our stones are produced with through-body colored concrete. Then they are tumbled to give them a naturally aged look. The three sizes of block are able to create seven different face sizes creating the randomly laid appearance of natural stones.

No mortar needed

There is no mess and mixing of mortar. Our kits are simply glued together. You squeeze special adhesive from a caulk gun. This makes construction and clean up a breeze.
