What you should know before buying
The manual makes a weather claim with no number behind it: the structure "has been designed to withstand extreme weather conditions such as high winds and accumulated snowfall." There is no wind speed, no snow load, and no test or code reference anywhere in the document to support it. Compare Riverstone, which puts 113 mph and a 1-second gust basis in writing on the Monticello, or Palram's Oasis, which carries a formal EN 1090 declaration. A phrase like "extreme weather conditions" cannot be checked against your local design wind speed, so it should not carry weight in a purchase decision.
No snow load figure, only the same unquantified "accumulated snowfall" claim.

Where to buy
Advertised prices, checked daily. Shipping is extra unless the retailer states otherwise — on a greenhouse, freight can change which seller is actually cheapest. We do not yet track a retailer for this model.

What we don't know
Anything marked not published means the manufacturer does not state it. That is a fact about the product, not a gap on our side.
Figures are the manufacturer's own, taken from its documentation. We have not tested this greenhouse, and reporting a rating is not endorsing it. Wind, snow, permitting and foundation requirements vary by site — confirm anything that matters with the manufacturer and your local building authority before buying. Prices are what the retailer advertised when we last checked and exclude shipping unless stated.
