This beautiful barn-style greenhouse gives you a year-round growing space in an attractive, heavy-duty aluminum frame and 10mm twin-wall panels.
Engineered to perform in harsh environments. The Grandio Summit's rugged durability makes it the most insulated of the greenhouses on the market and its barn shape design is both elegant and functional and allows plenty of growing space.
Made to meet the highest standards of amateur and professional gardeners, the 1.6mm profile aluminum frame provides a stronger and more durable build than its competitors and won't warp, melt, or crack like the PVC-based barn-style greenhouses. And the heavy-duty construction coupled with 10mm twin-wall polycarbonate panels provides the perfect thickness for winter insulation.
A wide range of features and accessories culminates in a well ventilated growing space with gliding double doors, our superb easy-to-assemble system, and an insulation (R) value of 1.89* and heat loss (U) value of 0.53 resulting in an amazing gardening and greenhouse experience.
The doors are hung from above which eliminates jamming and the door wheels are made from nylon for durability. The door wheel bolt is turned from solid brass with a smooth shank to reduce wear on the wheels.
The doors come standard with a magnetic catch with heavy-duty lockable door handles and included key.
Carefully designed, engineered, and built to the highest quality standards. Gardeners of all types will love the combination of strength, quality, features and especially the terrific value the Grandio Greenhouse offers.

How easy is the Grandio to assemble?
Very easy. Grandio designed and perfected the assembly process with you in mind. Your Greenhouse comes with the tools and a step-by-step assembly manual and video and if you have any problems you can call Grandio customer support at 1-866-448-8231.
Is a building permit required?
You may not need a permit for your Grandio, but it is always a good idea check before you get started. We recommend you check local ordinances and requirements before setting up your greenhouse.
Is it strong enough for windy or heavy snow locations?
Definitely. Grandio's are all designed to withstand the most hostile environments. We've added roof and eave supports to increase the strength and durability of the greenhouse frame. Just follow the included directions for securing your greenhouse and you'll enjoy many years of growing with your Grandio.
I live in the hot southwest will Grandio Greenhouses work for me?
For people who live in high-temperature areas of the country like Arizona, Texas, California, Nevada, or New Mexico we recommend our aluminum shade net. The aluminum shade net reflects the sun on the hottest days to help your greenhouse keep it's cool.
How do the automatic roof vent openers work?
The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the vent. As the temperature cools, the mineral shrinks and a spring closes the vent and resets the piston. The opening and closing of the vent is gradual allowing just the right amount of air flow for cooling. No electricity needed!
How large is the roof vent opening?
The vent opening is 18-3/4" width by 22-3/4” length.
What is the difference in polycarbonate thicknesses?
Polycarbonate is available in several different thicknesses and normally comes in single, double, and triple walled sheets that can vary in thickness from 1mm to 10mm. A good rule to remember is that the thicker the panel the better insulation you'll have for your greenhouse.

QUESTIONS & ANSWERSAsk a Question
I need an automatic opener, do you sell these separately, also shelving? what's shipping time more or less?
Yes you can order this seprately and the shipping is the same and free as always. You can find the accessories HERE
How much assembly is required?
It should take 1 day two people Here is the Manual http://grandiogreenhouses.com/manuals/Element/GRA_ELEMENT_FLATMOUNT_MANUAL.pdf
We have winds that sometimes hit over 60 mph, how well will this structure withstand these types of winds. Often when storms are coming over the Sierras from California we can get gusts higher than 60 mph.
It is recommended with those kinds of winds to get the base and the frame to base brackets.
What does basic with base mean? Can it set on grass?
Yes , Just choose the earth anchor option or call us at 732 806 7959
How wide is the door opening?
What is the height
This is 12 x 12 how tall are the straights, and how tall is it overall at the peak and do you sell or have something to make it into a greenhouse with light deprivation
61" on the side and 114" at the peak. add 3" with the base. I can give you a high quality shade net that blocks 50% of the sun at no extra cost. we do not have a complete light deprovation system at this point.
I see that these are all 12 feet wide. If someone were to purchase one that is smaller, and later decided to expand it, are there expansions that are available to make it larger? It would be purchased with the brackets for ground.
The length can be extended but not the width
Does it come in one crate? What are the weight and the dimensions of the packaging? Do you have a recommended contractor to unpack and assemble the greenhouse?
This comes with UPS in multiple boxes of very manageable sizes. You do not need anyone there for the delivery. We do not have any contractors to recommend for assembly.
