Building a canopy bed to enjoy outdoors is not a hard project if you have basic carpentry skills and tools. These steps will guide you through the project.
Step 1 - Arrange Corner Piers
The first thing you’ll need to do is lay out your canopy’s four corner piers. Roofing materials come in three-foot widths, which makes it simpler to plan out a 12x12-foot canopy. For one such as this, an 11x11-foot base will do, as it allows for an overhang of six inches for each side.
Step 2 - Create a Perimeter
Create an 11-foot square perimeter with your quartet of piers, making each one no less than two feet deep, one foot square. An anchor plate, which is manufactured to secure a 4x4 into the upper part of each pier, should be placed down. Be certain the piers add up to an even square.
Step 3 - Saw the Posts
Saw your four posts from 4x4 stock of even length, between about eight and 10 feet, and place each post in place. Double check to be sure the post tops are level. Leveling can be accomplished once they have been placed on an anchor plate and nailed secure. Therefore, each post will need to be vertical when cut. The best way to accomplish this task is by attaching braces first, then utilizing a crosscut hand saw to do the cutting.
Step 4 - Lay a Grid
You’ll next want to lay a 4x4 grid atop the posts, which serves to firm the frame and hold up the roof rafters. Begin by cutting the first 4x4, which will cover two of the post tops. Any adjacent posts will work. Now, you have your roof’s low side set.
Next, the upper 4x4 piece needs to be connected using six-inch lag bolts, using a hand wrench to secure them; it requires three lags for each joint. Also, be certain to drill a healthy pilot hole first. Now, measure two other 4x4s, which will span from the side of the horizontal piece to the front vertical post tops.
Your pair of framing pieces will rest atop the front posts, yet join right into the rear horizontal piece’s side. Each of these joints also require three lag bolts. The remaining post is to be placed atop the two side pieces and covers the whole width, including the side pieces. As before, also connect these with lag bolts, and also precede this task by drilling pilot holes.
Step 5 - Add Braces to the Frame
Use 4x4 stock to make your braces. Each of these needs to be approximately two feet long, with 45-degree cuts at either end. To make these cuts, use either a hand saw or a circular saw, and do so atop a sawhorse. Both braces should make for a small space between a horizontal and vertical 4x4 piece. Lag bolts should be used for each joint, but four to five-inch bolts are sufficient.
Step 6 - Install Braces Using Pilot Holes
Next, create pilot holes and install your braces.
Step 7 - Make the Frame
Make an 11-foot, six-inch frame utilizing 2x4s for the perimeter outside. Rafters should run at 24-inches on the center. You must also block between rafters, using two-foot intervals.
Step 8 - Put up the Grid
Put the 2x4 grid up and center it on the frame, then toe-nail each contact point using four galvanized framing nails.
Step 9 - Add Redwood Strips
Next, line redwood strips from one edge of the blocking to the other with galvanized casing nails. Make these uniform across the blocking’s length.
Step 10 - Nail Roofing Sheet
While overlapping by several inches, nail a translucent roofing sheet to your stripping, and seal it with silicone caulk. Then nail this with special roofing nails.
By following these 10 steps, you’ll have yourself an outdoor canopy of your own.
