Which Greenlyhouse Greenhouse Is Right for You?
Same steel frame, same panels, same warranty. What actually separates our four models is width, shape and the way you will use them. Here is the honest comparison.
What every model shares
Before the differences, the common ground, because it is most of the greenhouse. All four models are built on galvanized steel Omega profiles with 0.039 in steel thickness bolted to a 4 inch steel base, glazed in 6 mm twin-wall polycarbonate with about 85% light transmission and UV blocked, rated for winds up to 112 mph and snow loads up to 49 psf, and covered by a 10-year warranty. Every one gives full standing height at the ridge (8.04 feet on The Modern, 7.71 feet on The Cottage, 6.89 feet on The Classic and The Mini), ships free anywhere in the lower 48, bolts together in about a weekend with two people, and extends later in 6.6 ft sections.
So you are not choosing between good and better construction. You are choosing a width and a shape.

The Classic: the widest, and the one most people choose
At 9.84 feet wide, The Classic is the only model where the interior genuinely divides in three: a growing bed down each side and a center path you can turn around in. That layout is why it outsells the others. You can reach every plant without stepping in soil, run a cart down the middle, and still have both beds at full depth.
The arched profile sheds wind and snow well, and the panels are 6 mm twin-wall polycarbonate as standard. If you are hesitating between The Classic and anything narrower, and the yard allows it, the width is the thing you will be glad you paid for. See The Classic greenhouse, or check its six available lengths directly.
The Modern: straight walls, intentional looks
The Modern trades the arch for vertical walls and a crisp ridge. Two consequences. First, the look: it reads as architecture rather than equipment, which matters when the greenhouse sits next to the house instead of behind the garage. Second, the working height: straight walls mean full headroom right up to the edge of the beds, so tall crops and shelving work against the walls without leaning inward.
At 8.2 feet wide it takes a bed down each side with a walkway between. Glazed in 6 mm twin-wall polycarbonate. See The Modern greenhouse.
The Cottage: the little-house shape, in the most lengths
The Cottage is the model people pick with their eyes: a pitched roof and a proper garden-house silhouette, 7.71 feet wide. It is also the most precise to fit, because it comes in eleven lengths from 6.56 to 39.37 feet, in steps of roughly 3.3 feet, where the other models come in six.
One glazing choice to know: the Cottage comes in 6 mm twin-wall only. That is the thicker, better-insulated panel, which makes it a quietly strong pick for cold regions. See The Cottage greenhouse.
The Mini: for the spaces the others do not fit
The Mini is our narrowest model at 6.56 feet wide, made for side returns, patios and small urban yards. Inside, that means one bed or bench along a side and a walkway, and you work facing the plants rather than standing between two beds.
Nothing structural was cut: same steel profiles, same base and the same 6 mm panels as The Classic, with a 6.89 foot ridge, so you stand and work upright. If the honest answer to "where would it go?" is a strip along the fence, this is the model for that strip. See The Mini greenhouse.
How to choose in practice
- You want the roomiest working greenhouse: The Classic. Two beds, center path, the layout everyone pictures.
- The greenhouse will be visible from the kitchen window: The Modern, for the lines, or The Cottage, for the charm. Both look placed on purpose.
- Cold winters, and you want the warmest baseline: every model is glazed in 6 mm twin-wall polycarbonate as standard, so the choice comes down to shape and footprint rather than glazing. Our guide to twin-wall polycarbonate explains what that buys you.
- A narrow spot: The Mini, and nothing else will fit anyway.
- Still unsure about size: width first, then length. The greenhouse sizing guide walks through it step by step.
Your questions, in short
No. All four models use the same 1 mm galvanized steel Omega profiles on a 4 inch steel base. The models differ in width, shape and available lengths, not in construction.
All four models are glazed in 6 mm UV-protected twin-wall polycarbonate as standard.
Yes. All four accept 6.6 ft extension kits using the same frame profiles and panels, so you can start at one length and grow.
Yes. Every greenhouse ships free by freight carrier anywhere in the lower 48, flat-packed on a pallet, delivered to the curb.
