10x10 Greenhouse
There is no 10 ft x 10 ft frame in this catalog. Here are the two real sizes either side of it, with their actual growing space, and an honest view of which one suits which site.
We do not make a 10 ft x 10 ft greenhouse. The closest sizes we build are 10 ft x 6.5 ft at 65 sq ft and 10 ft x 13 ft at 130 sq ft, and 100 sq ft sits almost exactly between them. Neither is a 10x10 and we will not call one that - both are below with the real numbers so you can choose on your own site conditions.
10 ft x 6.5 ft
65 sq ft of growing space
35 sq ft less than the 100 sq ft you searched for.
The compact walk-in. Full 10 ft width, Dutch door at each end, and small enough to sit under most local permit thresholds.

130 sq ft of growing space
30 sq ft more than the 100 sq ft you searched for.
Benches down both sides with a genuine centre aisle, and an end wall free for potting and storage.
See 10 ft wide greenhousesWhich of the two you should take
A hundred square feet sits almost exactly midway between our 65 and 130, so this is a genuine decision rather than a formality.
Take the 10 ft x 6.5 ft if the site is the constraint: a short run between a fence and a path, a small lot, or a spot where anything longer would block access. Sixty-five square feet still gives you full standing width, both bench runs and a door at each end. It is a propagation and overwintering house rather than a growing room.
Take the 10 ft x 13 ft if the pad will take 13 ft. Thirty extra square feet over your target is a whole additional bench module plus a working end wall, and the marginal cost of length is far lower than the cost of the first six feet - the doors, the width and the frame profile are already in the price.
| Size | Growing space | Best for |
|---|---|---|
| 10 ft x 6.5 ft | 65 sq ft | Propagation and overwintering. Under most permit thresholds. |
| 10 ft x 13 ft | 130 sq ft | Benches both sides, real centre aisle, potting corner. |
| 10 ft x 19.5 ft | 195 sq ft | Year-round growing with a dedicated work and storage zone. |
Square is rarely the best shape anyway
A 10 x 10 is appealing on paper because it sounds tidy. In use, a square greenhouse is an awkward shape: you get one aisle and four short walls, and the corners are dead space you reach across rather than work at.
Rectangular plans use the same floor area better. Benching runs in continuous lengths, the aisle does a real job, and one end wall can be given over to potting and storage without eating into the growing side. If you have a 10 x 10 pad in mind, consider whether it could be 10 x 13 instead before the concrete goes in.
Why there is nothing at 100 sq ft
These frames are manufactured to metric lengths - 2 m, 4 m, 6 m and up - so at 10 ft wide the footprints step 65, 130, 195, 260 sq ft. One hundred square feet falls between the first two and no frame lands on it.
One more reason to know the real number: many jurisdictions set their permit exemption threshold at or near 100 sq ft, and some at 120 or 200. A 65 sq ft structure sits under almost every threshold; a 130 sq ft one may not. Check with your local building department before ordering - the answer is genuinely local and worth a ten-minute phone call.
10x10 greenhouse questions
Do you sell a 10x10 greenhouse?
No. We do not build a 10 ft x 10 ft frame. The closest sizes we build are 10 ft x 6.5 ft at 65 sq ft and 10 ft x 13 ft at 130 sq ft. Both are shown above with real square footage rather than one of them relabelled.
Which is closer to 100 sq ft?
Neither is close. The 6.5 ft is 35 sq ft under and the 13 ft is 30 sq ft over, so the decision is driven by your site and how you plan to use the space, not by which number is nearer.
Does 100 sq ft matter for permits?
It can. Some jurisdictions exempt accessory structures below a floor-area threshold, and 100, 120 and 200 sq ft are all common thresholds - but a permanent foundation, power or plumbing frequently triggers a permit regardless of size. Confirm with your local building department rather than relying on any general rule, including this one.
How strong are these frames?
1" x 1" hot-dip galvanized steel tubing, rated to shed 5 ft of snow. Wind ratings are stated per series and are not uniform: 75 mph on the Arc Series, 65 mph on the Loft Series, 65 mph on the Gable Series. Proper anchoring to a prepared base is what those ratings assume.
