How to build a safe Fire Pit - flames will not spread

Step 1: Set out the start of the Gazebo.  Place fence posts, three tall in a square shape, each post should be 5 blocks apart from another.





Step 2: Dig the pit.  It is easier to break this process into three.  Start with a 3 x 3 square in the center, this should be two blocks deep and will host the fire.  Next, build a 5 x 5 square 1 block deep, this will be the main floor.  Lastly, build four 5 x 2 rectangle, these should extend one block outside the fence posts, these will host the stairs.





Step 3: Replace the floor with any non-flammable block.  Add in the stairs, these should be 5 bricks wide and sit one block outside the fence posts.  Finish this step off by putting a block under the fence posts, then add a block to every side of the stairs, this block addition stops the spread of fire.





Step 4: Add the roof, layer one should be 5x5, layer two 4x4, layers three 3x3, obviously this can be any colour XD.





Step 5: Replace the bottom of the 3x3 central square with netherrack and light the blocks to create the fire (Lava can also be used).
