About 1 day with 2 people.

Do I need a concrete foundation?

No 👍. The greenhouse is fixed directly into the soil with ground anchors. A wooden or concrete base is optional.

Can I transport the greenhouse in a car?

Yes 👍. The longest package is only 2 m, so it fits in most passenger cars.

Will the greenhouse survive snowy winters?

Yes. Thanks to the arched design and galvanized frame, the greenhouse is stable and resists snow and rain accumulation.

  1. Happy with it

    Everything arrived complete, panels were pre-cut and protected with film. Frame is galvanized and feels like it will last years. If you’ve never built a greenhouse before, watch the corners and keep it square – then it’s easy.

  2. Bought it mainly for tomatoes + cucumbers. Plenty of space for two long beds and a small path. We added an automatic vent opener later and it helps a lot. Overall great value.

  3. Almost perfect

    Really like the size (3.14 m is a sweet spot) and the arched roof. One door handle felt a bit stiff at first, but after a few uses it’s ok. Everything else is great.

  4. Easy enough for two people. Sturdy and looks clean.

  5. Good greenhouse but expect a full day to build. A couple holes didn’t line up perfectly at first (maybe we tightened too early). Loosened everything, aligned, then tightened again and it was fine. Not a big drama, just be patient.

  6. Nice microclimate

    Plants are doing better than last year. It warms up quickly in the morning and doesn’t overheat that much when we open both door windows. Small typo in the manual, but overall assembly is DIY-friendly.

  7. Good for windy areas

    I picked the closer arch spacing (0.67 m) because we get wind here. It’s noticeably sturdy. Doors with the little windows are handy for quick venting. Would buy again.

  8. Looks great and holds heat well. Very happy.

  9. Delivery was fast and support answered my question about 4 mm vs 6 mm the same day. We installed it straight into the soil with the anchors (no foundation). It’s been stable so far even with rain + wind.

  10. Perfect size

    We went with the 3.14 m wide model and it fits our small backyard really well. Feels roomy inside (I’m 1.85 and can work without bumping my head). Came in several compact boxes and everything was packed neat. Built it in one long day with my wife. Only “issue”: we thought a bag of screws was missing, but it was hidden in the bottom of one box 😅

  11. Solid greenhouse, frame feels strong. We chose 6 mm panels for better warmth. Instructions are ok but not super clear on the first steps, so take your time. Once the base was square, the rest went smooth.
