How to Price a Pergola or Pavilion Kit: The 4 Things That Build Your Quote
Pergola and pavilion kit pricing comes down to four inputs: the roof size (and how cleanly it lines up with standard lumber), the timber series, the structure type, and the upgrades and engineering your site calls for. Get those four straight and you can price a kit from any company — and understand why two structures that sound identical can be quoted thousands of dollars apart. Most online guides hand you a dollar-per-square-foot range and stop there. That number is close to useless until you know what’s driving it, because size is rarely what explains a $10,000 gap between two quotes. This guide walks through each of the four, so the quote in front of you stops being a mystery and starts being a decision you can make with confidence.
The reason this matters: a price is just the sum of what a structure has to do. A pergola that has to throw real shade over an outdoor kitchen, stand up to your region’s wind, and carry power for lights and a fan is a different object than a decorative frame that does none of those things — even if both measure 12 feet by 16. The four inputs below are where that difference lives.
Key Takeaways
- The four inputs that determine pergola kit pricing — and how to use them to read any company’s quote
- Why two structures with the same footprint can be priced thousands apart — the standard-lumber waste factor most quotes never explain
- How your timber series (6,000 to 12,000) changes how much timber, weight, and cost go into the build
- Why a pergola and a pavilion at the same size differ in price by roughly 40% — and how to avoid comparing the wrong quotes
- What’s included in the kit price (finish is) and what isn’t (footings, electrical hookup, roofing)
- NEW: Real cost mechanics, engineering and finish citations, and a buyer’s FAQ — replacing the old quote-request checklist
First: Are You Comparing the Same Thing?
One gut check before the four inputs. If the prices you’re seeing are under about $10,000, you’re shopping kits — big-box and online pergolas — not custom heavy-timber structures, which generally run $8,000 to $49,000+. Both are legitimate, and a kit is the right call for plenty of homeowners. They’re just different categories built to different lifespans. Comparing a kit quote to a custom quote and wondering why they’re so far apart is comparing two different products. Know which one you’re pricing before you line up quotes.
Input 1: Roof Size — and the Standard-Lumber Waste Factor
The single most common pricing mistake is sizing a pergola by its post footprint instead of its roof size. Pergolas are priced — and built — by the dimensions of the shade structure overhead, not by the square of ground the posts sit on.
Here’s why that distinction costs people money. The roof of a well-built pergola overhangs the posts. On a Western Timber Frame structure, the posts sit roughly 12 inches in from each corner, so a roof that measures 12×16 stands on a footprint closer to 10×14. If you ask for a “12×16” thinking about the patio you want to cover, but the quote is built on a 12×16 footprint, you’ve just been priced for a larger roof than you described — or a smaller one than you need. Always confirm which number a quote is built on. The roof size is the one that determines how much timber goes into the structure and how much of your space actually sits in shade.
Roof size also drives the price in a way almost no quote explains: standard lumber lengths. Timber doesn’t come in any length you want — it comes in fixed sizes (8′, 10′, 12′, 14′, 16′, 18′, 20′). A beam that needs to be 16’2″ can’t use a 16′ timber; it has to start from a 20′ one, and you pay for the 3’10” of offcut you’ll never see. That waste compounds across every beam, every rafter, and the whole shade-plank grid. It’s why a 16×16 can cost almost the same as a 14×16 when the dimensions line up with stock — and why bumping to 16×18 can jump the price more than the two extra feet suggest. When two same-size quotes come back thousands apart, this is often where the gap is hiding. The question worth asking: does my design use standard stock lengths, or am I paying for offcut on every member? Western Timber Frame cuts its timbers from those same stock lengths, so design dimensions decide how much offcut a project pays for.
Picture the difference on your own patio. A roof sized to the actual table-and-chairs zone — the spot where people sit, eat, and linger — covers the part of the yard you’ll use. A roof sized a foot short to hit a round catalog number leaves the end of the table in the sun by 3 p.m. The measurement isn’t a formality. It’s whether your space is shaded where it matters.
Input 2: Timber Series — the Size of the Wood Itself
The timber series is the dimension of the timber your structure is built from, and it’s the input that moves the price the most — because it changes how much wood goes into the build. Western Timber Frame offers four series: 6,000, 8,000, 10,000, and 12,000. The numbers climb with the size of the members.

Those board-foot and weight figures are all measured on the same 14×22 pergola kit, which makes them a true apples-to-apples comparison. At an identical footprint, a 12,000 Series kit uses 2,738 board feet of timber against the 6,000 Series’ 886 — roughly three times the wood. That’s the clearest answer to “why does the series change the price so much”: you aren’t paying for a bigger pergola, you’re paying for a heavier, more substantial one at the same size.
Every series is engineered to the same standards — none is a step down in quality. They’re different looks at different scales. The 6,000 and 8,000 Series cover most residential projects, with the 8,000 the most popular. The 10,000 and 12,000 Series carry longer spans and the bold, architectural presence that large pavilions and commercial entries call for. Every series is built in Grade A Douglas Fir as standard, with structural Coast Redwood available as a premium; species and grade affect both how the timber looks and what it costs.
Shade is the other half of the series decision. Western Timber Frame standard kits deliver 80–85% ShadePrint™ — WTF’s measure of how much usable shade the structure actually casts as the sun tracks across the sky — depending on orientation, time of day, and season. That coverage comes from rafter density and shade-plank width, and it holds across the series; many aluminum and light-frame kits land at 40–50%. So the question worth asking any company isn’t only “how big is it,” but “how much of it is actually shaded at 2 p.m.?”
Input 3: Structure Type — Pergola, Pavilion, or Cabana
The third input is the one homeowners most often get wrong, and it makes quotes impossible to compare: structure type. A pergola and a pavilion at the same footprint can differ in price by roughly 40%, because they aren’t the same product.

The defining test is simple: can you see sky through the roof? If yes, it’s a pergola. If it has a solid roof, it’s a pavilion — “covered pergola” isn’t really a thing. A pavilion carries a full roof deck, roofing material, and heavier structural members to hold that weight, so its quote is built on more of everything. A cabana uses a shed-style, single-pitch (slanted) roof for a clean modern line; walls and screens aren’t part of it, so if you want them, factor them in separately.
This is one of the most common reasons two quotes don’t line up: tell one builder “pergola” and another “pavilion” while picturing the same structure, and you’ll get numbers that can’t be compared. Decide whether you want to see sky through the roof before you ask anyone for a price.
Input 4: Options, Engineering, and Your Site
The fourth input is everything you can choose to add to an already-complete structure — and it’s where two similar-looking quotes separate the most. It splits into three groups.
Options you choose.
- TimberVolt® Power Post System — posts drilled through the center for concealed wiring, pre-wired in the shop, ready for lights, ceiling fans, heaters, outlets, even a TV. It’s the most-chosen option across every kit, and integrating it upfront costs less and looks far cleaner than retrofitting surface conduit later.
- Taller posts — the standard is 8 feet to the bottom of the beams, enough clearance to walk, dine, and hang lighting. Going taller is an option that uses more timber and, because a taller structure catches more wind, often more engineering.
- FullWrap™ Roof, arched knee braces, and premium beam profiles — the timber details (Champion, Crescent, Roosevelt, and others) that change the structure’s character.
- Cantilevered roof — extending the roof past the posts (say, 10×10 posts carrying a 12×16 roof) buys dramatically more shade and usable space. Most of the cost in a heavy-timber structure lives in the roof, not the posts, so the roof-to-post ratio quietly moves the quote.
Engineering. Western Timber Frame has engineered structures across 7,000+ projects, with proven standard specs for most. For projects that need a permit, site-specific stamped drawings by an engineer licensed in your state are available as an option — worth knowing so you buy exactly what you need and nothing more. Structures anchor on EarthAnchor™ Structural Knife Plates: custom aluminum plates concealed in each post base that act as both a moisture barrier and a structural anchor, rated to 120+ mph wind and engineerable to 160+ mph where the site calls for it.
Your site. The same structure prices differently depending on where it lands. Wind design loads follow standards like ASCE 7-22; snow country needs deeper beams and tighter rafter spacing; coastal salt air calls for heavier-duty hardware; poor soil means larger footings. A company that quotes the same number for every site is either over-charging the easy ones or under-engineering the hard ones. Because a snowy lot needs deeper beams, Western Timber Frame details the frame from the loads that apply at that address.
What’s Included — and What Isn’t
A clear quote tells you both. With a Western Timber Frame kit, the finish is included in the kit price every structure ships pre-stained with two backrolled coats of UV-rated, water-based Sherwin-Williams exterior stain applied in the shop, plus touch-up stain in the box. There’s no separate stain bill waiting after delivery, which is a line many kit sellers itemize on top. You also get to specify your beam profile, knee brace style, and stain color from the standard menu at no added cost — those are choices, not upcharges.
What a kit price does not include is just as important to know going in:
- Foundation and footings — site-specific, and tied to your soil and local code (the basis for footings comes from the International Residential Code, which is why they’re never a fixed kit line item).
- Electrical connection for TimberVolt® — the system arrives pre-wired, but a licensed electrician makes the final hookup.
- Roofing materials for a pavilion — always sourced locally, because that costs less than shipping panels across the country.
- Installation labor — many families install the kit themselves over an afternoon to a day, thanks to pre-cut joinery; a contractor option is available if you’d rather not.
A company that’s clear about what isn’t in the price is usually clear about what is. If a quote is silent on footings, electrical, or roofing, that’s the conversation to have before you sign.
How WTF Custom Sizing Affects the Price
Most pergola companies sell a handful of fixed sizes — 10×10, 12×12, 14×14 — and you pick the closest one to your space. Because Western Timber Frame™ builds custom, every structure is sized to your actual backyard down to the 1/16th of an inch, including custom shapes a catalog can’t produce. That doesn’t automatically cost more; it means you pay for the structure your space needs rather than rounding up to the nearest stock size and living with the gap. The structure fits the home. The home doesn’t conform to the catalog.

These are orientation ranges for open-rafter pergolas, not quotes — the four inputs above move the final number. Pavilions, cabanas, and enclosed structures typically run 20–40% higher in each tier because of the solid roof and added materials.

If you’re gathering numbers from several companies, our questions to ask before getting a quote on a pergola kit pairs well with this guide.
Questions to Ask Before You Compare Quotes
You don’t need our quote to use this. Ask any company:
- Is this priced by roof size or post footprint?
- What are the timber sizes — posts, beams, rafters? (the single biggest variable)
- Does my design use standard stock lengths, or am I paying for offcut waste?
- Am I quoting a pergola (open rafters) or a pavilion (solid roof)?
- What’s the ShadePrint shade coverage at midday, and how is it measured?
- What’s not in this price — footings, electrical, roofing, labor?
The answers tell you what you’re actually buying. A quote that won’t name its timber sizes, or stays vague on shade and what’s included, is usually vague because the specifics don’t favor it.
Questions Homeowners Ask About Pricing a Kit
Pricing a Kit Without the Guesswork
Four inputs — roof size, timber series, structure type, and the options and engineering your site needs turn a confusing quote into a clear decision. Once you know what each one does, you can compare any company’s pergola or pavilion kit on the things that actually matter: how much timber goes into it, how much shade it throws, how well it stands up to weather, and what’s quietly left off the price.
