Outdoor Fireplaces: Build Guides, Comparisons, and Buying Advice
An outdoor fireplace is the most architecturally significant fire feature a patio can have. Where a fire pit is a portable or semi-permanent accent, an outdoor fireplace is a structural element, a built, permanent installation that anchors the patio as a defined outdoor living space and changes the way the entire area is experienced. The firebox, hearth, surround, and chimney form a vertical focal point that gives the patio a room-like sense of enclosure and permanence that no freestanding fire feature can fully replicate.
That architectural weight comes with a corresponding commitment. An outdoor fireplace requires a proper foundation, permitting in most jurisdictions, and either significant DIY skill or professional installation. The decision to build one is a considered investment in the property rather than an impulse purchase, and the planning that precedes construction determines the quality of the result.
This hub covers every aspect of outdoor fireplaces, from understanding how they compare to fire pits and which format suits your patio, to choosing a prefabricated kit versus building from scratch, to step-by-step construction guidance.
What Is an Outdoor Fireplace?
An outdoor fireplace is a fixed, built fire feature with a contained firebox, a hearth or base structure, and a chimney that exhausts combustion gases vertically. Unlike a fire pit, which radiates heat omnidirectionally at ground level, an outdoor fireplace directs heat outward from the firebox opening in a defined arc while venting smoke upward through the chimney stack, the same combustion geometry as an interior residential fireplace.
Outdoor fireplaces are built from masonry materials (brick, natural stone, concrete block, or stucco-finished block), from prefabricated refractory panels assembled into a kit surround, or as a combination of a prefabricated firebox insert set into a custom-built masonry surround. The firebox and flue must be constructed from refractory materials that can withstand sustained high temperatures, standard concrete block is not adequate for the firebox interior without a refractory liner.
Most outdoor fireplaces are wood burning, though propane and natural gas conversion kits allow some designs to operate as gas fire features.

Outdoor Fireplace vs Fire Pit: Key Differences at a Glance
| Factor | Outdoor Fireplace | Fire Pit |
|---|---|---|
| Heat direction | Directional (forward arc) | Omnidirectional |
| Seating | Linear or U-shaped, one direction | Circular, all sides |
| Smoke management | Channeled upward through chimney | Disperses at seating level |
| Patio footprint | Significant (permanent structure) | Small to moderate |
| Cost | High ($1,500 to $20,000+) | Low to moderate ($100 to $3,000) |
| Permanence | Fixed, structural | Portable or semi-permanent |
| Permits typically required | Yes | Sometimes |
| DIY feasibility | Moderate to difficult | Easy to moderate |
| Property value impact | Positive | Minimal |
For a full comparison across all these dimensions and guidance on which format is right for your specific situation, the outdoor fireplace vs fire pit guide covers the practical trade-offs in detail.
Who Should Consider an Outdoor Fireplace
An outdoor fireplace makes the most sense for homeowners who plan to stay in their property long term and want to create a genuinely exceptional outdoor living space, who have a patio or terrace large enough to accommodate a fixed fire structure without dominating the usable area, and who want a fire feature that contributes to the property’s resale value in a way that a portable fire pit does not.
Outdoor fireplaces are also particularly well suited to covered or partially covered patio structures where the chimney can be integrated into the roof design, and to patios that are used as outdoor rooms year-round rather than seasonally.
Planning and Permit Considerations
Outdoor fireplaces require building permits in most US jurisdictions. A permanent masonry structure with a foundation requires a permit in virtually every municipality; prefabricated kit fireplaces on a concrete pad typically do as well. The permit process involves submitting construction drawings showing setback distances from structures and property lines, chimney height calculations, and materials specifications.
Checking permit requirements before any design work or material purchasing is the right first step, permit requirements shape some of the key design decisions including chimney height, setback, and foundation specification. The how to build an outdoor fireplace guide covers permit and regulatory considerations as part of the pre-construction planning process.
