DIY: Window Awning

Step 1: Build the Bracket Mounts

Cut the 1×6’s in half, making 6 pieces of 4 feet long each. Cut the 8 foot, 2×4 boards, into 1 piece of 3-foot length and one piece of 4-foot length. Discard the excess. Cut the 2×6 in half, making 2 pieces of 5-foot length. At 1 end of one of these lengths, cut a 30-degree angle towards the top. At the other end, cut a 60-degree angle toward the bottom. Measure the angles from the same side. 

Cut the other 5 foot 2×6 in a mirror image of the first. Place the 4-foot length of wood against the end of the 3-foot length in the shape of an ‘L’. Pre-drill pilot holes and use wood screws to secure the 2 pieces together in the ‘L’ shape. Do the same thing for the other side.

Step 2: Mark and Cut Slat Locations

With the short length on the ground, attach the 5-foot length to the previously assembled “L” frame. Make sure the angles you cut are towards the long length and the ground. Starting from the top, mark lines level to the ground 2 inches long. From the back end of these lines, mark vertical lines to the edge of the board. You should have a number of “L” shapes marked.

Cut these notches out and repeat on the other bracket, using the first as a template. Use sandpaper to finish these cuts to ensure the proper fit of the slats.

Step 3: Prepare for Paint

Before assembling, it is advisable to completely sand all pieces of wood and the assembled frames in preparation for paint or staining.

Then, determine where you want the awnings located, in relation to the window, and mark them appropriately. Drill holes for lag screws in the frame vertical piece, which will go against the wall. Pre-drill the wall with the masonry bit for the lag inserts. Secure lag inserts in the wall at this time.

Step 4: Apply Finish

Now is the time to either paint or stain your awnings. This way you won’t get any stain or paint on the wall of your house.

Step 5: Assemble Slats

After allowing ample time to dry, it’s time to assemble your awnings. Fit each slat in place, one at a time, pre-drill, and securely install wood screws of at least 3-inch length, 2 per slat.

This project can be completed in about 3 or 4 hours.

Step 6: Apply Fabric

This is the fun part. You want material that can withstand the year-round weather. Pick a fabric that has neutral tones of the surroundings. Have fun, be creative!
