With just a weekend's worth of hard work, you can build a wonderful brick fireplace that will be a crowning centerpiece for your home. A do-it-yourself project like building your own fireplace is a satisfying and you might say fun task.

How To Build Your Own Brick Fireplace

Step 1

Mark the dimensions of the fireplace against the wall and the footprint of the fireplace on the floor, using painter's tape.

Step 2

Cut the metal lath with a utility knife to fit inside the painter's tape, so the dimensions of the fireplace are covered both against the wall and on the floor. Remove the painter's tape.

Step 3

Nail the metal lath into the wall and floor using common or drywall nails.

Step 4

Mix the mortar according to the package directions, as each brand of mortar differs.

Step 5

Apply a layer of mortar (1/2 to 1 inch thick) with a trowel to each brick before you lay it. Build a base layer, so the footprint of the fireplace is covered, laying bricks about 1/2 to 1 inch apart. Use your hand to smooth the mortar between the bricks if necessary.

Step 6

Continue mortaring and laying bricks in layers, so that you are slowly building upward. Continue building until the fireplace is built to the dimensions you desire. Fireplaces are generally 2 to 4 feet high, depending on their aesthetic relation to the height of the ceiling.

Step 7

Wipe away excess mortar.

Step 8

If the metal lath is visible in any spot on the edges of the fireplace, cover with a layer of grout. Allow the fireplace to dry completely, about 48 to 72 hours, depending on the brand, before lighting a fire.
