Cutaway detail of our standard firebox

Our fireplace kits have large firebrick-lined fireboxes

Our luxury fireplace kits have large lined fireboxes. Our firebox is larger than you will find on most other brands’ kits. Yet the size of the firebox, the opening, and the smoke chamber and chimney have been designed to draft well and offer decades of hassle-free use.

Though our fireplaces are designed for burning wood, you can always add a gas-fired log set if you please. Check out the diagram for the firebox dimensions. You can always download our dimensions and planning guides for more detailed information.

DIY Outdoor Fireplace 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.

Standard Fireplace Hearth
Firebrick lined firebox

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 are 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

Our complete building system gets results fast and easy

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 the bonding ability for a solid product 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 can 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 cleanup a breeze.

You have options when designing your see-through fireplace
