A faux fireplace can add character to a room. You can fill it with candles or put an electric fake fire in it to make it appear real. One of the best things about faux fireplaces is that they are portable, allowing you to move them from room to room or even put them away when it is not in use. Making a faux fireplace out of wood is a fairly simple construction project and a good one to practice woodworking.

  1. 1

    Assemble a box out of the 54-inch boards and the 46-inch boards. The 54-inch boards will be on the top and bottom, while the 46-inch boards make the sides.

  2. 2

    Screw the box together using two 3-inch wood screws at each corner. You should always drill pilot holes before you screw, they will help to prevent the wood from splitting.

  3. 3

    Assemble the 34-inch board and the 25-inch boards into an upside-down U shape. This arch will form the inner chamber where you build the "fire."

  4. 4

    Screw the boards of the arch together, using two wood screws per corner.

  5. 5

    Place the arch inside the box, centred horizontally in the middle of the box's bottom board.

  6. 6

    Attach the arch to the box by screwing through the bottom of the box and into the legs of the arch. Use two wood screws for each leg.

  7. 7

    Measure the height and width of the box and cut out two pieces of high-quality plywood to match. Cut a hole in one of the pieces that matches the size and position of the arch.

  8. 8

    Screw the pieces of plywood to either side of the fireplace frame, using wood screws every 6 inches. The solid piece of plywood makes the back, while the piece with the hole cut in it will be the front.

  9. 9

    Lay the 2-by-12-inch board on top of the fireplace to form the mantle. The back should be flush with the back of the fireplace, with an equal amount of overhand on the right and left sides.

  10. 10

    Screw the mantle to the fireplace with several wood screws.

  11. 11

    Fill in all of the screw holes with wood putty. Let the putty dry, then sand the entire surface smooth.

  12. 12

    Paint the fireplace with two coats of primer, allowing each coat to dry completely.

  13. 13

    Paint the mantle and outer surface of the fireplace with faux stone spray paint. There are many options available to choose from including granite, white onyx and marble. Allow the paint to dry.

  14. 14

    Paint the inside of the arch with a brick coloured spray paint. Allow it to dry, then hand-paint grout lines with acrylic paint.
