How to Build a Doghouse With a Flat Roof

Building a doghouse with a flat roof is an uncomplicated project that may go together easier than a doghouse with a pitched roof. Placing a doghouse with a flat roof in your dog run can provide your dog with additional exercise if your dog enjoys jumping and standing on the doghouse roof. Using treated lumber should help make the doghouse last despite weather conditions.

Instructions

    • 1

      Cut the 2-by-4 inch boards and plywood as indicated in supplies needed to build a doghouse with a flat roof.

    • 2

      Frame 4 of the 2-by-4 inch boards into a square frame by placing 2 of the 30-inch boards across from each other and 2 of the 26-inch boards 2 inches inside the edges of the 30-inch boards so that the edges are smooth. Repeat this process to create a second square.

    • 3

      Hammer 3-inch nails into the 30-inch boards so that the nails go into the 26-inch boards, securing the square frames. Be sure to use at least 2 nails in each board.

    • 4

      Hammer 3-inch nails into one 2-by-4-by-30 inch board into the inside of each corner, creating a cube. Also, hammer one 30-inch board 15 inches from one corner to create the door of the doghouse.

    • 5

      Attach the 1/2-inch treated plywood squares using the 3/4-inch nails to the bottom of the cube creating the floor, the top of the cube creating the roof, and three sides of the cube. Do not yet attach the plywood to the side of the cube where you will make the door; this is the side that has a board attached at the 15-inch mark.

    • 6

      Use the three hinges and screws to attach the smaller piece of 1/2-inch treated plywood, 15-by-30 inches, to the corner of the doghouse on the side you left open. Place the two latches on the board at the 15-inch mark. This will allow you to open the doghouse if necessary to clean it or to add bedding.
