16×24 Backyard Pavilion – Free DIY Plans

Ovidiu 30 GapDice RANDOM PLAN

This step by step diy woodworking project is about a 16×24 outdoor pavilion plans. I have designed this large rectangular pavilion made from 6×6 lumber, so it can be sturdy and simple to build as a DIY project. The roof has a 6:12 pitch and it is sheeted with plywood then asphalt shingled are installed. Take a look over the rest of our woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

How to build a 16×24 pavilion

Laying out the posts

Laying out the posts

The first step of the project is to layout the posts for the 16×24 pavilion. Use batter boards and string to determine the location of the posts. Apply the 3-4-5 rule to every corner of the pavilion, so you make sure they are right angled. Moreover measure the diagonals and make sure they are equal. Determining the location for the pavilion is essential, as you have to comply with the local building codes. Make sure the surface is level and remove the vegetation layer.



Dig 3′ deep holes into the ground with a post hole digger. Align the holes with attention and then fit form tubes. Fit the 6×6 posts with attention and align them using string. Use a spirit level to plumb the posts and then lock them into place with temporarily braces. Fill the tube forms with concrete and let it dry out for a few days. Setting the pressure treated/cedar posts in concrete is a lot better than using post anchors, as the posts will be locked in the concrete footers.

Top plates

Top plates

Use 6×6 lumber for the top plates of the pavilion. Use a circular saw to make the notches to beams, as shown in the diagram. Make parallel cuts inside the marked areas and then remove the excess with a chisel. Smooth the surface with sandpaper.

Cross supports

Cross supports

Make the notch to the middle of the cross supports. Use a circular saw set at 1 1/2″ and make parallel cuts inside the marked area. Clean the recess with a chisel and sandpaper.

Fitting the top plates

Fitting the top plates

Fit the top plates to the top of the posts. Plumb the posts with a spirit level and make sure the plates are horizontal. Check if the corners are square and align the edges with attention. Drill pilot holes through the plates and insert 8″ screws into the top of the posts.

Fitting the braces

Fitting the braces

Use 6×6 lumber for the braces. Double check if the posts are plumb and if the corners are square. Cut both ends of the braces at 45 degrees and then secure them into place with 5″ screws, after drilling pilot holes. These braces will really enhance the rigidity of the pavilion, so make sure you don’t take shortcuts and install them properly.

Top ridge

Top ridge

Use 6×6 lumber for the ridge beam supports and for the beam itself. Use a spirit level to plumb the supports and secure them into place with corner brackets. Fit the top ridge into place and use corner brackets to lock them into place, as well. Check if the corners are square and align the edges with attention. Use 8″ screws to reinforce the joists. Notice the half lap joint between the two components of the ridge beam.

Fitting the top ridge braces

Fitting the top ridge braces

Last but not least, you need to attach the 6×6 braces to the structure of the pavilion, so you can enhance the rigidity. Cut both both ends of the braces at 45 degrees and then secure them into place tightly, with 5″ screws.

Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-220 grit sandpaper and remove the residues with a damp cloth.

Top Tip: Apply a few coats of paint or stain to the components, to enhance the look of the project. Make sure you take a look over the rest of my pergola/gazebo/pavilion plans HERE. See all my free woodworking plans (over 1000) HERE.

    I’m currently in the process of building the pavilion, making my cuts. I had a question about the top ridge. On the first page it shows the length at 145 1/4, however in the diagram showing the half lap it’s showing as 146 3/4. Thank you.

      The diagram is correct. I’ve updated the cut list.

    Hi – thank you for the plans for this 16×25 Pavilion. My question is .. what would be all the new dimensions if we wanted a 4:12 roof slope? (how much do I reduce the height of the center ridge beam posts and what does it do to the angles to cut into the rafters?)

    I am just not familiar with roof slope measurements to figure that out? Any help would be greatly appreciated.

    Anyone have a rough cost for supplies on this? Thanks

    I am looking at building the 16×24 pavilion. The question I have is how long is the post that supports the ridge beam?

      Dimensions in the cut list

    Thank you for your designs and plans. We are interested in building the 16 x 24 pavilion. We are trying to get the structure permitted. Our county is in need of wind and weight testing. Are there any documents to help support this?
    Thank you again for your time.

    • Ovidiu at - Reply

      No, you need to work with a local engineer for that.

    Hi, i’m looking at the 16×24 pavilion. I’d prefer using 8×8 posts and top plates. perhaps the center ridge beam too with 8×8. Is it easy enough to just substitute the 6×6’s with 8×8’s? Thank you!!
