Designed and Built in Utah — About an Hour Away
Our structures are made in Utah — designed, engineered, and CNC-cut at our facility in Payson, about an hour away. Every one of the 7,000+ structures we’ve delivered nationwide since 2008 started as raw timber on that shop floor.
For a Herriman 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 curved pergola and arched trellis pictured on this page and a multi-structure backyard sanctuary with a pavilion, trellises, and privacy panels.
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 Herriman’s Climate & Lifestyle
Herriman sits at about 5,000 feet at the southwest edge of the Salt Lake Valley, with the Oquirrh Mountains to the west. The city’s published design criteria point to the ASCE Hazard Tool for wind, snow, and seismic loads at each address rather than one citywide number, so every structure is engineered to the loads for its own lot. Summers run hot, too: the Western Regional Climate Center’s record for the nearby Draper Point of the Mountain station (1985–2005) shows an average July high of about 94°F, which is why real shade matters here.
Herriman requires a building permit for a patio cover with posts to the ground and for any detached structure larger than 200 square feet; detached structures over 800 square feet need stamped engineering from a Utah structural engineer. City code lets open pergolas, trellises, and arbors sit as close as 3 feet to side and rear lot lines, and foothill lots on South Mountain fall under the city’s Hillside Overlay Zone. 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:
Foothill lots on South Mountain
Higher, sloping lots in the Hillside Overlay Zone, where grade, views, and wildfire rules shape the footing and roof design.
Agricultural and larger lots
Lots in Herriman’s agricultural zones, where homes share space with limited agricultural uses and a structure is placed around the way the property works.
Rosecrest, Olympia, and newer communities
Master-planned neighborhoods, where a timber structure becomes the first big feature of a new backyard.
Herriman is named for Henry Harriman, one of its 1851 founders; the spelling changed over time. The community incorporated in 1999 and became a city in 2001. Today residents gather at city parks like J. Lynn Crane Park and W & M Butterfield Park, and Butterfield Canyon climbs into the Oquirrh Mountains just west of town. 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 Herriman
Every structure is a Custom-Engineered Kit — purpose-built for your space, architecture, and lot.
Custom Pergolas: Best Fit For Herriman
With July highs in the mid-90s, a Herriman 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 sits in a brand-new backyard or on a foothill lot with valley views. 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 Herriman’s foothill 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: Herriman’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 Herriman
Design Consultation
In person or remote, designed around your lot, home, and views.
Engineering for Herriman 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 Herriman 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 Herriman’s requirements for patio covers, accessory-structure setbacks, hillside rules, and site-specific loads.
