to the firepit in this picture which tells me it is not a wood burning firepit. If you are planning on a wood burning firepit a good rule of thumb is 7'. If you are using a gas firepit then it would be the same as a coffee table in front of a sofa which is 12 to 18". You also want to consider if you
around the firepit. Before building your seating, circle some chairs around the firepit to "try out" the distance. You don't want to be too close and get overheated or have sparks hit you. Good luck!
high sitting area nicely complemented by the firepit
between the firepit and seating? and what height is the fire pit.
put in a firepit. Some explode when heated, sending small sharp fragments flying.
I concur with Anne, your local fireplace expert should be able to help. Find one at the National Fireplace Institute website: nficertified.org.
love the seating and the area around this firepit
