Designed and Built in Utah — About 35 Minutes Away
Our structures are made in Utah — designed, engineered, and CNC-cut at our facility in Payson, about 35 minutes away. Every one of the 7,000+ structures we’ve delivered nationwide since 2008 started as raw timber on that shop floor.
For an American Fork 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 elevated deck and pergola and the park 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 American Fork’s Climate & Lifestyle
American Fork sits at about 4,600 feet between Utah Lake and the mouth of American Fork Canyon. The city’s garage and carport checklist calls for a 30-inch minimum frost depth, and the Utah Snow Load Study puts ground snow loads across most of the city at roughly 31 to 35 psf, rising toward the canyon. NOAA’s 1991–2020 climate normals for the nearby Pleasant Grove station show an average July high of about 93°F and about 41 inches of snow a year, so a structure has to handle both summer sun and winter snow.
American Fork’s accessory building ordinance requires a building permit for any accessory building larger than 200 square feet and keeps accessory buildings in the rear yard, covering no more than 25% of it. They can’t be taller than the house or 25 feet, or more than 20 feet tall within 10 feet of a property line, and they sit at least 12 feet from the house and 5 feet from interior side and rear lot lines, or 40 feet from a side line along a street. The city’s permit FAQ also lists decks and patio covers as permit projects. 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 Main Street
Mature lots near the city’s historic center and Robinson Park, where a structure has to fit an older home and an existing yard.
Homes toward American Fork Canyon
Bench lots on the north and east side, closer to the canyon, where views, canyon winds, and higher snow shape the footing and roof design.
Decks and two-level yards
Walkout lots where an elevated deck and pergola turn the space above and below into usable shade, like the deck pictured at the top of this page.
American Fork was incorporated in 1853, and Steel Days, the city’s summer celebration, has been held since 1945. The city maintains 27 parks, and Timpanogos Cave National Monument sits up American Fork Canyon. A timber structure earns its place here by fitting that history and standing up to real snow, wind, and summer sun.

Structures We Build in American Fork
Every structure is a Custom-Engineered Kit — purpose-built for your space, architecture, and lot.
Custom Pergolas: Best Fit For American Fork
With July highs averaging about 93°F, an American Fork 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 tops an elevated deck or sits on a lot facing the canyon. 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 American Fork’s walkout decks 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: American Fork’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 American Fork

Design Consultation
In person or remote, designed around your lot, home, and views.
Engineering for American Fork 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 American Fork 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 American Fork’s accessory building setbacks, rear-yard coverage limits, and deck and patio cover permits.
