What are the pros and cons of a peninsula (three-sided) fireplace vs a see-through fireplace?
A see-through fireplace puts one fire between two rooms — two finished faces, one shared flame, and a lower cost than two separate units. A peninsula wraps glass around three sides, turning the fireplace into a glowing room divider you can see from almost anywhere. The peninsula is the bigger showpiece; the see-through is the more practical two-space solution. Both trade some heating punch for all that glass.
What each layout does well
A see-through shines where two rooms meet — living room and dining room, kitchen and den, sometimes indoor space and covered porch. One appliance, one gas line, one vent run, and both spaces get the flame. A peninsula juts into an open floor plan with glass on three sides, defining zones in a great room without building a wall. It reads as architecture, not just an appliance, and in the right mountain-modern build it's the first thing every guest mentions.
The costs of all that glass
Multi-sided units give up things single-sided fireplaces take for granted. More glass means heat spreads in every direction instead of pushing into one room, so neither space gets the full punch — treat these as ambiance-first and let your heating plan stand on its own. Framing, finishing, and clearances multiply with each exposed face, which multiplies cost. Daylight passing through the firebox can make the flame look thinner at midday, and a TV above one is rarely workable. Placement is also vent-driven — the flue path has to work for a unit standing away from exterior walls.
Getting it right the first time
Nearly every modern multi-sided fireplace is direct-vent gas, which is what makes these installs possible at all — sealed combustion, no chimney required. But the design decisions are permanent, so this is a project to plan on paper with the vent route, the furniture layout, and the gas line together. That's a free design consultation for us.
