How to Build a Brick Fireplace With a Chimney in Minecraft - Making a Brick Fireplace with a Chimney

1. Dig out a 2 brick by 4 brick hole up to the ceiling on an exterior wall of your base.

2. Dig out the 2 bricks on the floor in the center of the hole you just made.

3. Line the hole with brick blocks. Place 2 netherrack in the floor holes and cover the rest of the fireplace 1 block deeper, if you want a fireplace escape route make the fireplace either 1x2x3 or 2x2x3(these dimensions are: height x width x length/back) with a hallway that leads somewhere safe(to be extra safe add a sword or bow and arrows) and a minecart behind where the flame will be.(it will work even if the fire is... flaming, but just in case add some water 7 blocks away)

4. Extend the chimney as high as you want out of the side of your base.

5. Light up the netherrack with your flint and steel to complete your fireplace.
