Custom Arbors & Trellises Kits

The Perfect Outdoor Touch

Why Choose an Arbor or Trellis?

Your outdoor space deserves more than just furniture and plants—it deserves character. Arbors and trellises are the unsung heroes of backyard beauty, effortlessly elevating any landscape with depth, charm, and function. Whether framing a pathway, defining a cozy nook, or supporting your favorite climbing vines, these structures transform undefined spaces into inviting retreats.

Arbors: These graceful, often arched structures create a welcoming entryway or focal point. They provide shade, support for climbing plants, and a grand sense of arrival.

Trellises: Sleek and versatile, trellises serve as vertical gardens, privacy screens, or artistic accents. They maximize space while adding greenery and structure to your yard.

What Our Arbor & Trellis Customers Say

Ann Anderson
This is our second project with Western Timber, and once again they exceeded our expectations. From working with the design to the final installation by the crew, every step was professional and thoughtfully executed.
The awning and arbor they created have completely transformed our backyard into the retreat we envisioned. The craftsmanship is exceptional, and the finished result feels nothing short of magical.
We couldn’t be happier and highly recommend Western Timber
David Osmond
If you’re thinking of adding a pergola or arbor to your yard, you HAVE to go with these guys!! We seriously couldn’t be happier with the end result, as well as with their professional level of customer service through the whole process. We knew we wanted to have a pergola in our backyard, and after looking at several options, nothing matched the level of quality we were hoping for. Then a good friend suggested Western Timber Frame, and we are so glad they did. From the moment we walked into their showroom, we knew we had found the right company for the job. They were courteous and helpful in assisting us with our questions, and took the time to understand what our goals were. The quality of the workmanship was stellar, and the time it took from selection to install was fantastic. We were also impressed with the price and affordability of their product. Having just built a house and all the frustration of dealing with many different styles from “professionals” in the industry… working with Western Timber Frame was a breath of fresh air!!
Mark Peterson
When we first started thinking about putting a pergola in our yard, we knew it was not going to be an easy job due to the oversized timbers and location. Well, we were wrong. The job took only one day for installation and a few hours of paver work. What a pleasant surprise as most jobs seem to linger on and on. Added to that, the quality of the pergola and arbor are first rate and we are glad we didn’t let others influence our decision to use a small independent contractor. This job would have sunk most who tired – but our Design Manager took the time to really study the possibilities and recommended just the right size, location and type of look we were searching for. The installation crew was efficient, quiet and most conscientious about getting the job done just right.
Way to go guys. You’ve put a winning product with a winning team.

I heard good things from others about Western Timber Frame, and we decided to go with them for a large trellis over our rock walkway. They were friendly and detail oriented at every step. They came to do the footings and later for the trellis. We had them install it and I’m very glad we did. We are going to plant wisteria on our trellis. It grows very big and heavy and can pull down arbors and trellises if they are not strong. No vine is pulling this thing down! It’s incredibly well built. The footings went deep and the timbers are thick.

How is a timber frame arbor or trellis engineered?

Our stamped sample timber frame arbor or trellis packages use a 115 mph ultimate design wind speed as a calculation input, not a storm survival rating, with ground snow from 30 psf to 50 psf depending on the site and Exposure B. A licensed structural engineer prepares a stamped package for your address from those criteria, and fabrication follows that package. Your address may require different criteria, and your package controls.

What holds an arbor or trellis down in wind?

Wind uplift is resisted by the whole connection path: the post, its through-bolts, the plate, the anchors, the footing, and the soil beneath it. The engineer checks every step of that path, and your stamped package sizes the foundation for the calculated uplift at your address.

How are arbor and trellis posts anchored?

Because the posts run in a line rather than around a frame, each arbor or trellis post takes a quarter-inch aluminum plate that runs two feet up inside it, and the post is through-bolted to the plate. The plate anchors to concrete with four half-inch by nine-and-a-half-inch anchors, and your stamped package sets the bolt count and the footing size.

How much wind load does an arbor or trellis post take?

In our stamped 3 ft × 18 ft trellis package, each post carries 114 pounds of calculated lateral load. That is a design load for that package, not a capacity rating, and arbor loads are calculated for your own plan.

How much does a timber arbor or trellis kit cost?

Western Timber Frame arbor kits start at $3,900 in the 4000 Essential series and trellis kits at $4,900 in the 6000 Standard series, each for the smallest published plan, with shipping included and engineering quoted separately.
