How to make a bike shed

Updated February 21, 2017

Bikes parked outside without shelter, left vulnerable to the elements, can succumb to moisture damages, such as grease-purged chains or rust, caused by rain, snow and dew. Build a simple bike shed with a roof and walls on three sides to keep your family's bicycles protected. Place a bike rack in the shed so you can keep the bikes organised and locked. The following bike shed is 8 feet wide and will accommodate a 6-foot-long bike rack.

Dig postholes for corner posts, using a posthole digger. At the front and back, dig the post holes 8 feet apart. At the sides, dig the postholes 6 1/2 feet apart. Dig the holes 2 feet deep and 10 to 12 inches in diameter. File the holes with 6 inches of gravel.

Place marks 1 1/2 feet up from the ends of four, 8-foot-long, pressure-treated posts.

Place the posts in the holes and fill the holes the rest of the way with concrete. Make sure the marks are sitting at the top of the concrete, to ensure the posts are all the same height. Use a level to ensure the posts are plumb. Use scrap wood to temporarily brace the posts in place.

Trowel the top of the concrete so it has a slight slope going away from the posts, to promote water runoff away from the wood. Leave the concrete to dry for one day.

Secure horizontal, 8-foot-long, 2-by-6 boards to the top of the posts at the front and back, using wood screws. The boards go on the outer-facing post planes and the top edges of the boards and the posts need to be flush.

Secure horizontal, 6-foot 4-inches-long, 2-by-6 boards to the top of the posts at the sides.

Affix a 6-foot-high, 8-foot-wide, 3/4-inch-thick plywood panel to the back to create the back wall, using wood screws.

Affix 6-foot-high, 6-foot 7 1/2-inches-wide panels to the sides, to create the side walls.

Paint or seal the plywood and 2-by-6 boards to protect them from water damage.

Add an 8-foot 2-inches-long, 6-foot 8-inches-wide piece of sheet metal to the top to create a roof. Secure the sheet metal to the 2-by-6 boards with roofing screws. The sheet metal is a bit larger than the dimensions of the shed to allow for slight overhang and water runoff from the wood.
