Build a budget-friendly garden arbor from 2x4s and other inexpensive structural lumber following our easy building plan. This classic wood arbor is beautiful for a backyard wedding arch or just everyday backyard decor!
A few years back, my sister asked me to build a garden arbor for her backyard wedding. So I got to work designing a classic wood arbor that is easily portable and built with 2x4s and other affordable redwood lumber. You can see more great 2×4 projects here in our 2x4andMore building plan series — plus this gothic arch arbor and vegetable trellis and outdoor coffee table with built-in drink coolers are favorites of mine.

Backyard Wedding Arch Design
My sister gave me this wedding arch inspiration photo to work from:
She trusted me and knew that I would be able to come up with something great. (Because that’s what #remodelaholic brothers do!) So I started to look at the inspiration design to see how I could build it. Based on that style, I also knew I wanted a few other features in this wooden wedding arch:
- portable, to be built in sections and easily assembled at the outdoor wedding site
- tall enough to stand under for the ceremony, reception, and photos
- affordable, using inexpensive 2x4s and other structural lumber
- durable redwood lumber, so we could continue using it after the wedding
I had built a gothic arch vegetable arbor before, so I had some ideas of how I wanted to build this mini pergola style arbor. I started sketching my version and this is what I came up with.
As soon as I had a good idea of the design, I built a model in 3d to figure out how I was going to build it. Given my list of requirements above, I found that having a top and two side sections was to best option and corbels would end up holding it all together.

- (50+) 2 1/2″ – Deck Screws
- (20+) 1 1/4″ – Deck Screws
- (1) Gal. – Stain ( I stained the pieces first then assembled it. Pick the color that works best for you.)
- Wood Glue (I used wood glue to hold the side trellis pieces together.
- Circular saw
- Table saw (for ripping 2×4 trellis pieces to width)*
- Orbital sander
- Drill bits
- Tape Measure
- Saw horses
*If you don’t have a table saw, you could alternately use 2x2s, 1x2s, or even smaller square dowels. Those aren’t as readily available in the redwood lumber, though, so ripping the material down was my preferred option.
Steps to Build a Wood Wedding Arch Garden Arbor
Purchase the building plan with cut list and dimensions here in the shop.
1: Cut Out All The Pieces
Start by cutting out all the pieces and shaping any ends. Sketch out the pattern on some card stock, cut out the pattern and transfer it on the ends of the top trellis board. Then cut it out using a jigsaw.
After it is cut to shape, sand it with an orbital sander. (I prefer to also sand the edges round for a softer look.)
Now is the easiest time to stain all the pieces, before assembling.
3: Assemble the Arbor Side Sections
4: Assemble the Top Trellis Section
5: Assemble the Garden Arbor
