Motorcycles, while having many advantages over cars, are still subject to the same weathering as any automobile. If you have a motorcycle, you may not want to devote the space for a full garage. Instead you can build a simple shelter sized for your motorcycle. This shelter is basic enough that it requires no building permits or major equipment, but will provide protection from sun, rain, hail and snow.
Measure a 5-by-10-foot space on the ground. This will be the size of your shelter, which will accommodate most motorcycles.
Dig a square hole at each corner of the space. The holes should be 1-foot wide and 2-feet deep.
Mix a batch of concrete according to the directions on the bag. Pour 6 inches of this concrete into each hole and let it harden to form a base for the posts to rest on.
Place an 8-foot high, 4-by-4-inch post in the centre of one of the holes. Use a level to ensure that it is standing up straight.
Mix another batch of concrete and pour it into the hole around the post. Use the level to hold the post up straight until the concrete hardens.
Repeat this process for the other three posts, making sure that they are all standing up straight as the concrete hardens.
Use clamps to temporarily secure the 10-foot boards to the sides of the shelter. The tops of the boards should be flush with the tops of the 8-foot high, 4-by-4 posts.
Screw the boards to the posts with four 3-inch wood screws per post, positioned in a square. If desired, you can drill pilot holes first in order to reduce the chance of the wood splitting. You can screw them by hand, but if your drill has a screwdriver attachment, it would make the job much faster.
Use clamps to secure the 5-foot, 3-inch boards to the front and back of the shelter. Screw them in place with wood screws in the same square pattern, but slightly lower so that they do not hit the screws already in the post.
Screw a galvanised joist hanger at the halfway point of each side board on the inside of the shelter, with the open ends facing up. The hanger will have holes in it to screw through. Use the level to make sure that both of the hangers are level, otherwise the next step will be very difficult.
Slide the 5-foot board into the joist hangers to create a crossbeam in the centre of the shelter.
Screw two 5-by-5-foot pieces of plywood to the top of the shelter to form the roof. They will meet at the crossbeam in the centre.
A second person is needed for assembling the support posts: one to hold the post and the other to pour the concrete. If you have access to a 5-by-10 plywood, you can make the roof a single piece.
