DIY Latticework Porch Awnings

Use a measuring tape to measure up from the ground next to one corner of the porch to the desired height of the awning. Add 2 feet to this measurement to determine the height of the 4-by-4-inch hardwood posts you will be using to support the latticework awning.

Dig a 2-foot hole next to each of the four corners of your porch. Position the holes along the two shorter ends of the porch so when you sink the support posts they will sit flush against the narrow sides of the porch.

Cut four pieces of 4-by-4-inch hardwood to the height you determined in Step 1 using a circular saw. Stand the four posts upright in each of the four holes you just dug and use a level to ensure that they stand straight. Fill the holes with cement to form a firm foundation for your porch awning.

Measure the distance between the outside edges of the two hardwood posts positioned along one of the long sides of the porch using the measuring tape. This is the length you will use to build your awning frame. Find the width of your awning frame by measuring the distance between the outside edges of two posts installed along the narrow side of the porch.

Add 24 inches to the length measurement you determined in Step 4 and cut four pieces of 2-by-4-inch hardwood to this length using a circular saw. You will use these boards to construct the support for your latticework awning top.

Place two of the 2-by-4-inch hardwood boards on either side of two of the posts installed along the long side of the porch. The posts should be sandwiched between the two pieces of 2-by-4-inch hardwood and the top edges should be aligned.

Drive 4-inch wood screws through the 2-by-4-inch hardwood boards into the posts to secure them in place. Repeat this process with the remaining two 2-by-4-inch boards, installing them on either side of the two posts along the other long side of the porch to complete the basic awning frame.

Cut four pieces of 2-by-4-inch hardwood to the width of your awning plus 24 inches using the circular saw. These boards are the cross braces that you will use to install the latticework awing top.

Lay the four 2-by-4-inch hardwood boards upright on their narrow edges, positioning them perpendicularly across the boards you installed in Steps 6 and 7. Space the boards evenly along the length of the awning frame. These boards should overhang the boards below by about 12 inches on both ends.

Drive 4-inch wood screws at an upward angle through the awning frame into the perpendicular 2-by-4-inch hardwood boards you just installed to secure them. Use screws on both the inside and outside edges of the boards on both ends.

Have a large sheet of latticework cut to the overall length and width dimensions of your awning frame. The length of the latticework should be equal to the length of the double boards attached to the support posts and the width should be equal to the length of the perpendicular boards running crosswise across the top of the awning frame.

Lay the sheet of latticework flat on top of the awning frame. Adjust the latticework so it is centered over the frame. Drive nails from a nail gun down through the latticework into the awning frame to attach it.
