How to Build a Triangular Dog House With Plywood

by Laure Justice

Make a triangular dog house for your outside dog.

Make a dog house inspired by geometry to make your yard look good and keep your outdoor dog comfortable. You do not have to spend a lot of money or invest a lot of your time in the project. You can use some basic building supplies or scraps left over from other projects to make a triangular dog house. These simple dog houses have one big advantage over other dog house styles; water and snow cannot pool on the roof of a triangle-shaped dog house.

A-Frame Dog House Tutorial

Step 1

Put the sides, which also form the roof, on top of the base so the 24-inch long edges line up. Ask your helper to hold the pieces in position.

Step 2

Set the screws every 4 to 6 inches, 1/2 inch up from the bottom edge, all the way along each side panel. Do not worry if you notice a small gap where the boards meet. You will be caulking the gaps in a later step.

Step 3

Line up the top edges at the peak so the edges form a small V-shape, and set screws every 4 inches. Drive the screws through the side panel closest to you and into the other side panel. Make sure the tips of the screws do not stick out.

Step 4

Squirt a thin line of weatherproof caulk into the inside of each joined seam, leaving 1/2 inch on each end plain. Allow the caulk to dry for several hours.

Step 5

Measure your dog's shoulder height and hip width, then draw a rectangle this size on one of the triangular end pieces. Use the jigsaw to cut out the door.

Step 6

Slide one end piece in each end of the triangular dog house. If the pieces do not slide in easily, use the pencil to mark how much you need to cut off, and use the jigsaw to trim down the shape.

Step 7

Ask your helper to hold the end pieces in place and drive the screws through the roof sides and into the end pieces. Roll the dog house 1/3 turn to set the screws through the bottom edges.

Step 8

Set the dog house upright and run a line of weatherproof caulk along the external peak of the roof and to seal any gaps you see where the end pieces meet the roof sides.
