Family Build [Photo 1: wide angle — combined pavilion and pergola attached to the brick home, pool in foreground] Melanie K. and her husband wanted a covered space attached to their home — a pavilion to anchor outdoor dining, a pergola to extend the shade across the patio. They sent us photos and measurements. We sent back a 3D rendering of the structure in their actual yard, against their actual house. Looking at it, they spotted something we hadn't: "upon looking at the rendering we realized the peak of the pavilion against the house had an ugly view of our house's roof. We decided to add planking there to cover that." A sightline issue, fixed in software, weeks before any timbers were cut.

The Difference You Can See. The Engineering You Can Trust.
Most pergola companies sell you a kit you assemble. We sell you a structure that can’t be assembled wrong.
While others ship flat-pack panels in cardboard, our custom timber frames arrive on freight trucks —
precision-cut, hand-fit, ready to stand for decades, not seasons. Every beam, every post, every
connection is designed not just to stand, but to endure.
Since 2008, more than 7,000 of these structures have shipped to all 50 states. What we’ve learned: the pergola industry needed a reset. Homeowners deserved more than vinyl that warps, aluminum that burns to the touch in July, and light-frame wood held together with visible bolts and hope. So we built something different.
The Physics Of Permanence
Heavy timber doesn’t behave like prefab. It does different things — and not by accident. Five engineering decisions separate a structure that lasts from one that’s just present.
ShadePrint™ — 80%+ Functional Shade
Pergolas are bought for shade, but most don’t deliver it. Through higher rafter density and wider shade planks, ours hit 80%+ functional shade coverage — close to what you’d feel under a mature tree. Pre-fabs settle for 40–50%. The number isn’t theoretical; you feel it the moment you step underneath.
Thermal Mass — Cool To The Touch
Heavy timber absorbs heat. It doesn’t radiate it. In 115°F desert sun, you can lay a hand on one of
our posts and feel almost nothing. Try that on a metal or aluminum pergola in August and you’ll get a
contact burn. For families with kids and pets running around barefoot, this isn’t a marketing feature.
It’s just physics.
