Simple DIY Pergola ( Grape Arbor ): Free Building Plan

A DIY arbor ( also know as a pergola or trellis ) is one of the most enchanting structures you can create for your garden!

A pergola not only defines an inviting outdoor room and creates shade, but also offers the perfect structure to grow flowering or fruiting vines such as wisterias, roses or grapes.

This grape arbor is located in a public garden near our home. I really like how attractive and DIY-friendly it is.

The DIY arbor starts with footings – very important.

Due to climate and soil type, there are different requirements for footings. Consult a professional local contractor when creating footings for arbors and pergolas. 

Before digging any holes for the post footings, it is really important to call your local utility and cable companies (such as Blue Stake ) and have them mark the location of any underground services. Smart, safe digging is a must.

( Some of the helpful resources are affiliate links. Full disclosure here. ) This elegant grape arbor uses Simpson post base PBS44A to connect the posts to concrete footings. See more in resources section at the end.

Step 1 ( after the footings are set ): install 4×4 posts for the DIY pergola.

The drawing shows the center to center of these posts.Before securing all the posts, hold each post plumb in place, or brace the posts so they stay plumb, use a 2×4 and a level to make sure the top of all the posts are at the same height. Trim posts if necessary.

Use wood screws to attach each post to the base. Simpson Strong Tie, the manufacturer of these awesome post bases and other connectors, has put together an Installer’s Pocket Guide which you can download here for more details.

Step 2: Add 2×6 beams to pergola

Rest the first 4×6 beam on center over a pair of 4×4 posts. The overhangs should be of equal length. Secure the beam to the posts with pocket hole screws or Simpson mending plates. These will be covered by the 2×6 trim pieces as shown in next step.

Step 3: Add 2×6 trim pieces to grape arbor

These 2×6 trim pieces serve two functions: they add more details and richness to the pergola design, and they help strengthen the post-beam connection.

Each trim piece is attached to the beam with 4 screws, and to the post with 8 screws spaced vertically at 12″ on center.

These braces also add beauty and strength to the DIY pergola. They can be screwed onto the post trim with pocket hole screws.

First install the two horizontal 2x4s on each side. Use a plywood or even cardboard template to cut out the shapes of the four 2x4s that form the diamond pattern. Feel free to improvise on the center designs.

Space 11 runners at equal intervals along the length of the beams. Take time to measure the spacing and overhangs to keep the whole set of runners in alignment.  Simpson Strong-Tie RTU2 is used here to connect two 2x members – the beam and the runner – intersecting at 90 degrees. First mark each of the connectors and secure them to the beams. Then insert and screw each runner to the connectors.

  1. I’m a huge fan of DIY projects and gardening also. It looks like a beautiful garden. Thanks for your DIY arbor building plan hope this plane help to grow up my garden.

  2. Hey Amanda! Love your grape arbor, great tutorial and it’s nice and solid too. I’ve included it in our “15 Sturdy Grape Vine Trellis Design Ideas For Your Backyard Arbor” article and pinned to my Growing Fruit Pinterest board. Thanks for the info, it’s great! Elle 🙂

  3. Great article. After a few decks and cedar shakes on my gables – if anyone uses cedar and wants a great protectant I would recommend trying Cabot Australian Oils. After a few coats the sealant lasts for years (especially on vertical surfaces).

  4. Do you have a printer friendly version of these instructions? Like a pdf or something? Or is there one and I’m just missing it? Thank you!

  5. Amazing idea, I’m a huge fan of DIY working and I got some good idea about building a Arbor. It helps me to building a arbor for my garden gate.

    Thanks for the share.

  6. Is this structure one that you could attach a swing to in the center? I’m looking for a plan that could provide a swing option.

    • hi bridget, this one can very easily be adapted to hang a swing. i would have a good builder making sure the footings and beams are strong enough! =)

  7. Please fix step 4
    Your instructions call for 2×4 at 2′ 8″ but upon closer inspection, both the real pictures and the model show a 2×6 horizontal brace. The diamond shape braces still being 2×4. Wouldn’t want anyone else to run out of the lumber like i did. Otherwise great post

    • hi shane, thank you so much for the feedback! i think both 2×4 and 2×6 will work here as the horizontal braces, but you are right about the actual pergola, i will add notes to the post. thank you! 🙂

      • Hi, would this design work with 13′ beams? We would need to bury 3′ in the ground, and we need the arbor to be 10′ tall to be over 3 steps and bedroom french doors that lead to the backyard. Thanks!

        Also, what kind of wood do you recommend?

        THanks!

        • hi dana, yes you can increase post height, however, i don’t think burying wood post is the best solution because wood can rot when exposed to constant moisture. i would use metal post anchors designed to keep wood off the soil. 🙂

  8. I love this! We had one for our wedding, and then brought it home for our garden. We left it when we moved, so I would love if my husband could build one like this.

  9. This is so perfect! We are needing to replace our arbors. Our grapes are maturing and need a sturdier arbor then we have for them now. Pinning this for later. Thank you!!!
