Looking to add a brick shed to your backyard? An outdoor shed is a great answer to many little obstacles, whether you want a mini-garage for your new motorcycle, or a storage shed for your lawnmower and other outdoor tools. Building one out of brick is no easy task, especially for the amateur, but it can be done.

Step 1 – Prepare

Before any building takes place, be sure to check for any building permits required in your city or county. The larger you want your shed, the more likely you’ll need permits.

Plan, measure, and then mark off the length and width of your shed, choosing an area that's level and clear of major obstacles and debris, such as large rocks and tree roots.

Step 2 – Set Your Base

Dig down at least eight or 10 inches where you plan to lay your brick, and at least six inches wide. Pour in a couple inches of sand as a base, and use your hand tamper to compact the sand and make it level.

Make a frame of 2x4s to set at the edges of the hole. Then, mix and pour a concrete mixture and fill in the frame. Take another 2x4 cut to the length of the hole and drag it along to top of the other pieces of lumber to get a good, level foundation. You’ll need to let it dry at least overnight.

Step 3 – Set Up Your Posts

You’ll need a 4x4 post in each corner of the shed. These will be used to keep your bricks straight and orderly as you lay them, as well as hold up your roof later.

Dig holes at least four inches deep, right along the inner corners of your concrete, and ensure at least six feet of your poles remain above ground (or however high you want your roof to be). Pour more concrete around each post, being careful to keep each one perfectly vertical. Level the concrete, and let it dry over night.

Step 4 – Lay the Brick

Tie a rope off between two posts at about the height of your first layer of brick. This will act as a guide to ensure your brick remains straight and level.

With the trowel, begin laying mortar down followed by the first run of bricks. As you move up layer by layer, off-set each layer by half a brick for maximum stability (the brick on one layer should sit in the middle of two bricks on the layer below). Every other layer, you’ll need to cut a brick in half for the ends.

As you lay mortar, be careful that no holes are left for water to seep through. Also, before laying more mortar on top of a layer of bricks, use your level to ensure everything is even, and continue moving your rope up with each level. This will help keep from developing a twisted look to your shed.

Continue laying brick, leaving an opening for your door, until you get about three or four inches from the top of your 4x4s. For the doorway, measure the door you have for your shed, and add at least four inches (for two 2x4s as a door frame) to know how much space to leave as you lay brick.

Step 5 – Frame and Secure Your Roof

Build your roof frame on top of the 4x4s, using 2x4s. If there is a gap between the wood and the brick, that's fine, as it will allow for ventilation. Also, make sure there's an overhang (at least five or six inches) from the brick. If you want your roof to be angled to allow water run off, add an extra 2x4 along the side of the door. This will offset the angle of the roof so water runs off the back.

Attach your steel sheet roof to the wood frame with nuts and bolts, allowing overhang on the other side to prevent water from getting into any openings between lumber and brick.

Step 6 – Assemble the Frame and Attach the Door

Use 2x4s to build a door frame around the brick doorway you left. Your door should fit snugly, so do a quick test fit in the frame once it's in to be sure no modifications need to be made. Attach hinges and a latch to both the door and frame, marking as needed to be sure the pieces line up. Do one more test to check for issues with the door such as not latching or sticking.

And with that, your shed is finished!
