Backyard fireplaces have quietly become the most-requested hardscape upgrade in the country, with average builds running $4,500 to $18,000 installed. The catch is that 90 percent of the wow-factor designs you scroll past online require permits, structural footings, and a mason who charges $85 to $140 an hour. The good news: there’s a parallel universe of simple outdoor fireplace ideas that deliver the same warmth and gathering point for a fraction of the spend. The trick is matching the design to your local code, fuel type, and how much labor you’re willing to do yourself.

Prefab Steel Insert Kits
Prefab kits like the Necessories Bluestone fireplace ($2,200) or the Belgard Bordeaux Series ($3,800 to $5,400) ship as palletized stone blocks with a steel firebox and chimney already engineered. You stack the units onto a poured concrete footing, mortar the joints, and add a cap stone. Assembly takes a weekend with two people.
These kits meet IRC Chapter 10 setback requirements when installed 10 feet or more from any structure. Total installed cost runs $3,500 to $7,500 including the 4-inch concrete pad. The look reads as built-in custom masonry, which is why they’ve dominated suburban backyards since 2018.
Concrete Block Painted to Look Like Stucco
For the budget-conscious, an 8×16 inch CMU concrete block fireplace skinned with stucco delivers a modern Spanish or contemporary aesthetic for $1,200 to $2,400 in materials. Stack the blocks dry-fit first, then mortar with Type S masonry mortar. Use a steel insert from Brick Anew or Buck Stove ($450 to $900) to handle the firebox heat.
Finish with a base coat of stucco followed by a Behr Premium Plus Masonry or Sherwin-Williams Loxon XP topcoat in warm white, ivory, or charcoal. This design works best for clean modernist yards. Pair it with a 4-inch poured concrete bench wrapped around the fire and you’ve created a functional gathering zone for under $3,000.
Steel Wood-Burning Fire Pits With Cooking Grates
If a permitted fireplace feels like overkill, a 36-inch steel fire pit from Solo Stove ($420), Breeo X Series ($600), or TIKI Brand ($349) handles wood burning duty with near-smokeless secondary combustion technology. These run on locally cut hardwood and need no permit in most jurisdictions when set on a non-combustible surface.
Add a Tractor Supply heavy-gauge grate ($65) and you have an outdoor cooking station. The lifetime cost is roughly 95 percent lower than masonry, with the trade-off of less heat radiation and zero architectural value. Combine with a flagstone or pea-gravel patio for a complete weekend build.
Brick Open Hearth With Chimney
The traditional open-hearth design with a stacked brick chimney remains the gold standard for resale value. Pavestone or Belden brick at $0.60 to $1.40 per unit, mortar at $14 per 60-pound bag, and a refractory firebrick liner ($4 to $7 each) build the firebox. The chimney needs a 4 to 1 throat-to-flue ratio per the National Fire Protection Association standards.
This is a 60 to 80 hour build for an experienced DIYer or $7,500 to $14,000 for a mason. Pull a building permit, since most jurisdictions classify any outdoor fireplace with a chimney over 6 feet as a permitted structure. Setback from property lines runs 10 to 25 feet depending on local zoning.
Gas Burning Fireplace With Linear Burner
For instant-on convenience, a stainless steel linear burner from Warming Trends ($1,400 to $2,800) or HPC Fire ($900 to $2,100) installed inside a stone or stucco surround delivers a modern look without smoke or ash. Run a 1/2 inch black iron gas line from the meter on natural gas, or use propane from a buried 250-gallon tank.
A licensed plumber handles the gas connection because most jurisdictions require permits and a pressure test before backfill. Total installed cost runs $5,500 to $12,000 including the surround. Operating cost runs roughly $1.20 to $2.50 per hour on natural gas at current rates.
Stacked Stone Veneer Over a Steel Frame
This hybrid approach uses a welded steel frame ($600 to $1,200) bolted to a concrete pad, faced with manufactured stone veneer like Coronado Stone or ProVia Heritage Series ($6 to $12 per square foot). A steel firebox liner handles the heat, and the lightweight veneer skips the footing requirements of full masonry.
Total installed cost runs $3,200 to $6,800 and matches the appearance of a $14,000 custom build to all but the most trained eye. The structural advantage matters in regions with high water tables or freeze-thaw cycles, since lightweight veneer construction tolerates ground movement far better than rigid masonry.
Chiminea or Clay Outdoor Fireplace
The traditional Mexican chiminea remains the simplest outdoor fireplace option. A handcrafted clay unit from Sunnydaze or Blue Rooster runs $180 to $450 and sets up in under an hour on a paver base. Burn small split hardwood like oak or hickory in pieces under 12 inches.
Clay chimineas crack within 1 to 3 years if left exposed to freeze-thaw cycles, so move them under a covered porch for winter or invest in a heavy-duty vinyl cover. Cast iron chimineas like the Sunnydaze 3-piece ($340) tolerate weather better but heat up extremely fast, creating a burn hazard within 18 inches of the unit.
Repurposed Industrial Materials
One of the most popular simple outdoor fireplace ideas in the past three years has been the industrial-look corten steel cube. A 30 or 36 inch box welded from 1/4-inch weathering steel ($800 to $1,800 for materials) develops a rich rust patina over 6 to 12 months. Drop in a propane or gas burner kit and you have a sculptural fire feature.
For something even cheaper, a halved 55-gallon steel drum on legs makes a campfire-style hearth for under $150. Both designs need 10 feet of clearance from structures and combustibles per the International Fire Code, but neither typically requires a permit when used as a portable appliance.
