-To raise a fireplace off the floor, you can use simple L brackets. Simply install them on either side of the baseboard and adjust until it is level with your desired height. Make sure that they are secure before proceeding to put in firewood or other items on top of them.
-Another option would be to build a simple wood frame that rests on the floor and is about one inch high. Any type of wood can work for this project, but cedar or pine will last longer without rotting.
-Using concrete blocks works well if you need something stable and sturdy in your fireplace. Make sure not to stack them too high so there is plenty of room left for air circulation around each block. Building an elevated platform out of bricks may also work, though over time they tend to get worn down from heat exposure and weathering effects from rainwater coming into contact with the surface area below it when the windows are open during springtime showers.
-An eco-friendly option for raising your fireplace is to use natural wood stumps. These are usually free, but you may have to go out into the wilderness and find them yourself before bringing it back home. Stumps can be used as a temporary solution if they are not too big or heavy.
