Wood pallets make handy building materials. They are widely available, often for little or no money. They are also very durable and relatively easy to transport. If you have a few wood pallets lying around, you can easily use them to build a simple animal shelter, with just a few additional materials. If you don't have any wood pallets handy, ask your local building supply store or lumber yard: they may have extra pallets that they will let you have.
Angle two wood pallets together to form an A-frame. The base of the frame should coincide with the width of a wood pallet. Join the two wood pallets at the correct angle with L-shaped brackets.
Lift the A-frame onto a third wood pallet. Ask a friend for assistance with this step: the A-frame will be fairly heavy. Attach the A-frame to the base with additional L-shaped brackets.
Measure the dimensions of the triangular opening at the back of the shelter. Cut a large triangular piece of plywood to fit. Always wear safety glasses when operating power saws. Screw the large plywood triangle to the back of the shelter.
Measure a smaller triangle for the front entryway of the shelter. Leave plenty of clearance below the front triangle for your animal to freely enter and exit. Cut the smaller triangle to fit from scrap plywood and screw into place at the front of the shelter.
Stretch a waterproof tarp over the exterior of the shelter and staple it into place. Fold all edges tightly and neatly to prevent pockets where water could accumulate.
Line the floor of your animal shelter with carpet scraps or an old blanket.
Always exercise caution when operating power saws.
