Designed and Built in Utah — About 45 Minutes Away
Our structures are made in Utah — designed, engineered, and CNC-cut at our facility in Payson, about 45 minutes away. Every one of the 7,000+ structures we’ve delivered nationwide since 2008 started as raw timber on that shop floor.
For a Lehi buyer, that means an in-person consultation, timber cut in-state, and real joinery you can drive to before you commit. We’ve built here, too, including the Pizzeria Limone patio pergola and the backyard pergolas and pavilion pictured on this page.
It’s also why the U.S. Small Business Administration named us the 2026 SBA Utah District Manufacturing Small Business of the Year.
Designing Timber Structures for Lehi’s Climate & Lifestyle
Lehi sits at about 4,560 feet at the north end of Utah Valley, between Utah Lake and Traverse Mountain. Lehi’s last-published design criteria list a 43 psf ground snow load, 115 mph wind (Exposure C), and a 30-inch minimum frost depth, and the city notes its criteria are being updated. NOAA’s 1991–2020 climate normals for the Utah Lake Lehi station show an average July high of about 92°F and about 26 inches of snow a year, so a structure has to handle both summer sun and winter snow.
Lehi’s accessory use code keeps accessory buildings out of the required front yard and limits them to 30% of the rear yard. A structure under 16 feet tall can sit 2 feet from side and rear lot lines, 5 feet at 16 to 24 feet, and 8 feet above that, as long as it stays 10 feet to the side or 6 feet behind the house, and most residential zones cap height at 24 feet or the height of the home. The city’s permit checklist covers detached garages and sheds over 200 square feet, and the code doesn’t count un-walled pergolas as structures, so we confirm the rules for your project with the city. We work through those requirements with you during design, before a single beam is cut.
Our standard engineering starts at 115 mph. Where the project requires a higher design wind speed, the structure is engineered for that requirement. We also engineer to your lot’s real snow load, soil, and exposure.
Neighborhoods we design for:
Established neighborhoods near downtown
Older lots near Main Street and the Lehi Roller Mills, which opened in 1906, where a structure has to fit a mature yard and an existing home.
Planned communities on the benches
Newer homes in areas like Traverse Mountain, where planned-community design guidelines or HOA review can shape the materials, colors, and size of a backyard structure.
Commercial patios and gathering spaces
Restaurants, hotels, and parks, like the Pizzeria Limone pergola and the curved hotel trellis pictured on this page.
Lehi calls itself Utah’s sixth oldest city, and the Lehi Round-Up has brought the community together for nearly 90 years. Thanksgiving Point covers 155 acres, and the Murdock Canal Trail runs 17 miles from Orem into Lehi. A timber structure earns its place here by fitting that history and standing up to real snow, wind, and summer sun. For statewide engineering and climate detail, see our Utah timber structures page.
Structures We Build in Lehi
Every structure is a Custom-Engineered Kit — purpose-built for your space, architecture, and lot.
Custom Pergolas: Best Fit For Lehi
With July highs averaging about 92°F, a Lehi patio needs shade that actually works. A pergola has to deliver real shade and read as a permanent part of the home, not a mail-order add-on, whether it shades a new-build backyard or a restaurant patio. That’s where custom engineering separates from a catalog cover.
Many aluminum and light-frame pergola kits provide significantly less coverage, while our ShadePrint™ approach measures actual coverage and can reach 80–85%, varying by orientation and time of day. Unlike metal, timber has low thermal conductivity, so it doesn’t heat the skin as quickly in the sun and surfaces stay more comfortable to the touch. Engineered for Lehi’s new-build lots and summer sun, the Dovetail Difference® interlocks the timbers without metal brackets or exposed fasteners, with no visible hardware to loosen. Add lighting and power through TimberVolt® — engineered in, not bolted on.
The same craftsmanship scales up: Lehi’s businesses, parks, and event venues use commercial timber pavilions to turn a patio into a year-round, instantly recognizable space.
Our Timber Frame Design & Build Process in Lehi
Design Consultation
In person or remote, designed around your lot, home, and views.
Engineering for Lehi Conditions
Engineered to your lot’s soil, grade, snow load, and wind, based on the specific conditions of your property. We provide engineering documentation to support permitting and stamped drawings prepared by a licensed engineer where the project and jurisdiction require them.
Fabrication & Quality Control
Every timber is cut in-house at our own Payson shop, on CNC machinery we own and run ourselves — not sent out to a third-party fabricator. That means the same team that engineers your Lehi structure also cuts it, with one line of control and accountability from design to delivery.
Warranty Coverage
Every Western Timber Frame structure carries a limited structural warranty. Length runs from 3 years on Deck Structures to 25 years on the 12K Series, based on the series you purchase.
Delivery & Installation Support
Ships as a Custom-Engineered Kit with complete instructions; DIY-friendly, or we can coordinate installation support.
We build around local permitting, including Lehi’s accessory building setbacks, rear-yard coverage limits, and planned-community design guidelines.
