How Much Does a Greenhouse Cost?
Greenhouse pricing is usually opaque: base price here, freight there, glazing as an upgrade. Here is what a complete kit actually costs, with real numbers from our own catalog.
Real prices, by model
These are our live starting prices - they update automatically with the catalog, so they are never stale:
| Model | Starting price | Best for |
|---|---|---|
| The Mini | from $2,990 | Side yards and patios, one bench and a walkway |
| The Cottage | from $3,190 | Classic pitched-roof look, a bench down each side |
| The Modern | from $3,190 | Straight walls, maximum headroom at the edges |
| The Classic | from $3,090 | The widest: two full beds and a center path |
Within each model, the price scales with length. Longer costs more in absolute terms but less per square foot, which is why the honest comparison between two sizes is always the price per square foot on the product page.
What actually drives the price of a greenhouse
Four things, in order of impact:
- Floor area. More footprint means more steel and more panels. This is the dominant factor.
- Frame material and thickness. Galvanized steel costs more than thin aluminum tube, and it is the difference between a structure rated for storms and one that folds. Our frames use Omega-shaped galvanized steel profiles with 0.039 in steel thickness - the reasoning is in our steel vs aluminum guide.
- Glazing. Single-wall film is cheap and short-lived; glass is expensive and fragile; 6 mm twin-wall polycarbonate sits in the durable middle: insulating, hail-resistant, UV-protected. We fit it as standard on every model rather than selling it as an upgrade.
- Shipping. A greenhouse ships by freight on a pallet, which typically costs several hundred dollars if billed separately. Ours is included, anywhere in the lower 48.
What a complete kit includes (and what it does not)
Included in every Greenlyhouse price: the full galvanized steel frame, pre-cut 6 mm twin-wall polycarbonate panels, door, all hardware, illustrated step-by-step instructions, protective crate delivery, free freight shipping in the lower 48, all taxes, a 10-year limited warranty against manufacturing defects, and the current 6 free gifts bundle worth $579 of growing accessories.
Not included, and worth budgeting honestly: the base (compacted gravel, a slab or a timber perimeter - materials typically land in the low hundreds of dollars for a DIY weekend), and any optional accessories beyond the gift bundle, like extra automatic vent openers or an irrigation system.
Why the cheapest greenhouses cost more in the end
A sub-$1,000 greenhouse from a marketplace listing is usually thin aluminum tube with single-wall panels held by clips. Two predictable outcomes: it struggles to hold heat (so the growing season barely extends), and the first serious storm tests it - often terminally. Buying twice is the expensive way to buy.
The middle of the market - a rigid steel frame with twin-wall glazing - is where the price-to-lifespan curve makes sense for a structure that lives outdoors year round. Our buying guide covers how to compare kits beyond the sticker price.
Kit vs building your own: the real math
Self-building from lumber and polycarbonate sheet can undercut a kit on materials, but the gap narrows fast once you price rot-resistant lumber, fasteners, hinges, and glazing bars - and it disappears when you count the design time and the absence of any load rating or warranty. A kit arrives engineered, pre-cut, pre-drilled and rated; assembly is a weekend with two people, not a framing project.
Your questions, in short
No. The price on the product page is the price you pay: taxes included, freight shipping included, no additions at checkout.
Nothing on top of the listed price - freight delivery to all 48 contiguous states is included, in a protective wooden crate, delivered curbside within 14 days of purchase.
A compacted gravel base for a mid-size greenhouse typically costs a low-hundreds amount in materials if you build it yourself over a weekend. A concrete slab costs more. Our foundation guide walks through the options.
Payment is taken in full at checkout today. If that changes, the product pages will say so - we do not do hidden credit offers.
The gable ends (front and back walls, door) cost the same whatever the length, so every added section dilutes them. If you are hesitating between two lengths, the longer one is almost always the better value.
