Made in the USAThe founders of Riverstone Industries have brought their decades of greenhouse experience to the new Monticello 8X8 Aluminum Greenhouse. It features classic gable styling and is a beautiful addition to any garden.

Shipping included for the contiguous United StatesEvery aspect of the Monticello has been designed for durability. The frame is made of the highest quality extruded aluminum and the roof has dual joists to withstand high snow loads. The greenhouse is coated with a special UV protectant to prevent discoloration, and it comes with an industry-leading 10 year warranty.

Riverstone Monticello GreenhousesThe panels are of the highest quality as well, as the Monticello includes 8mm twin-wall polycarbonate wall and roof panels that are both UV-stablilized and impact resistant. These provide much more insulation than the typical 4mm or single-wall panels found on other units, and are the same panels used in commercial-grade greenhouses.

10 Year Limited WarrantyThe Monticello is designed to be assembled in just four hours or so depending on how much help you have with just common household tools. Features like quick-connect screws, the integrated base, the integrated gutter and downspout system, and the pre-hung hinged door and vent speed up the process.

The tall interior height of the greenhouse gives you plenty of working space for even the tallest plants. The Monticello 8X8 provides the durability of a commercial greenhouse with the practicality of a hobby unit, ensuring that it will provide your family enjoyment for years to come.
