Most commercial greenhouse manufacturers won't show you pricing until you talk to a sales rep. We will. A Conley's commercial greenhouse runs anywhere from about $20,000 for a basic cold frame to over $294,000 for a fully-equipped three-bay polycarbonate production facility — and our online configurator gives you a real budgetary estimate for your specific project in under five minutes.
Below are five real configurations from our configurator, with itemized pricing and clear notes on what's included. Compare them side by side to see how structure type, equipment package, and project scale each affect the budget.
The same 1200 Series cold frame structure, at two equipment levels.
View 1 of 5: 1200 Series basic cold frame greenhouse, 30 by 96 feet (1 of 5)
1200 Series
30' × 96' · 2,880 sq ft · $6.97/sq ft
$20,069
$6.97 per sq ft
Steel frame, double-layer poly roof, polycarbonate doors, HAF fans for air movement, motorized roll-up sides. Good for season extension, propagation, nursery overwintering, and applications that don't need active climate control.
What's included
View 1 of 5: 1200 Series fully equipped cold frame with fan-and-pad cooling, 30 by 60 feet (1 of 5)
1200 Series
30' × 60' · 1,800 sq ft · $17.59/sq ft
$31,665
$17.59 per sq ft
Same 1200 Series structure with fan-and-pad cooling (including end wall vent), evaporative pads, forced air heater, and manual roll-up sides. Equipment alone more than doubles the per-square-foot cost — without changing the structure itself.
What's included
The same 3600 Series gutter-connected commercial greenhouse, at two equipment levels.
View 1 of 5: 3600 Series commercial greenhouse with mechanical climate control, 30 by 96 feet (1 of 5)
3600 Series
30' × 96' · 2,880 sq ft · $18.83–$22.19/sq ft
$54,217–$63,915
$18.83–$22.19 per sq ft
Full gutter-connected commercial structure with poly film roof, polycarbonate end walls, insulated steel doors, fan-and-pad cooling, and forced air heater. Climate is handled entirely by mechanical cooling and heating — no natural ventilation, ridge vents, shade, or motorized accessories. A common configuration for arid climates where evaporative cooling handles the load.

3600 Series
30' × 96' · 2,880 sq ft · $36.34–$40.41/sq ft
$104,652–$116,383
$36.34–$40.41 per sq ft
Same 3600 structure with motorized roll-up sides, ridge vents, motorized internal shade system, and rolling benches added on top of mechanical climate control. Built for serious production growers, scaled nursery operations, and institutional buyers wanting complete environmental control plus a finished growing space.
What's included
The price range reflects truss spacing — 12' on-center on the low end, 8' on-center on the high end. Tighter spacing may be needed depending on your site's snow load, wind load, or local code. Your sales rep confirms final spacing during the formal quote.
View 1 of 5: 7500 Series three-bay polycarbonate production greenhouse, 30 by 96 feet per bay (1 of 5)
7500 Series
30' × 96' × 3 bays · 8,640 sq ft · $30.85–$34.00/sq ft
$266,543–$293,728
$30.85–$34.00 per sq ft
Three connected bays of premium polycarbonate gable greenhouse, fully equipped. Notice the per-square-foot cost is actually lower than the single-bay 3600 fully equipped above — gutter-connected greenhouses share certain costs across more growing area as projects scale up. This is why larger commercial projects often have better per-sqft economics than smaller ones, but only for gutter-connected structures.
What's included
Want a deeper look at the 7500 Series specifically? The 7500 Series cost guide breaks down three live-priced builds — a school, a wholesale nursery, and a commercial production house — with full line-item pricing.
A greenhouse is a system, not a square-footage purchase. Four things drive cost more than anything else:
Equipment package. The examples above show this clearly. The same 1200 Series cold frame costs $6.97/sqft basic and $17.59/sqft fully equipped — equipment more than doubles the per-sqft price without changing the structure. The same pattern holds at commercial scale: the 3600 climate-only is roughly half the cost per square foot of the 3600 fully equipped. For most commercial projects, the equipment package equals or exceeds the cost of the structure itself.
Structure type and scale. Cold frames like the 1200 Series are standalone — buying three of them costs roughly three times as much because they don't share walls or systems. Gutter-connected commercial structures like the 3600 and 7500 series share walls and certain systems, so per-square-foot costs typically drop as projects scale up. This is why the three-bay 7500 above is cheaper per square foot than the single-bay 3600 fully equipped.
Covering choice. Poly film is the most affordable option and works well for production growers — it's the standard for the 3600 Series. Twin-wall polycarbonate costs more but is more durable, provides better insulation, and looks more permanent — standard on the 7500 Series and a common upgrade for schools, retail garden centers, and institutional buyers.
Site and engineering requirements. Some pricing shows as a range because final structural specs depend on your location. Tighter truss spacing (8' on-center instead of 12') may be required for higher snow loads, wind loads, heavier equipment, or local code. Different series also include different built-in features — for example, the 7500 includes structural details for ridge ventilation that need to be added separately on the 3600, which can affect cost when comparing options. Your sales rep confirms the final spec for your site during the formal quote.
The numbers above cover the greenhouse system — structure, covering, and equipment. A complete project typically also requires:
