Gabriel Ash Portico Series Greenhouse Kit 11 x 14 ft. with Tempered Glass Panels and Red Cedar Wood Frame Buy Cheap 2025 New

The only wooden greenhouse kit endorsed by the Royal Horticultural Society.

The Portico Series of greenhouses are made from Western Red Cedar, which is a stable and long-lasting wood often used in harsh climates where strength is a necessity. When red cedar absorbs moisture, its naturally occurring preservatives are triggered and the moisture is quickly released into the air, helping to give red cedar its longevity. All of the red cedar used for these greenhouses comes from certified or sustainable forests.

The Portico greenhouses are covered in tempered safety glass and weather protected with powder-coated aluminum features. The aluminum gutters and downspouts are designed for easy compatibility with rain barrels and water tanks. The cedar roof is protected by hand-turned cedar caps and neoprene gaskets for additional weather protection. The steep-pitched roof helps prevent snow buildup, while an automated heat-sensitive ventilation system runs the length of the greenhouse, releasing heat at the most advantageous point.

Each greenhouse sits on its own aluminum plinth, which raises the greenhouse off the ground and provides a stronger fixing point for the foundation.

Any Portico Series greenhouse should be professionally assembled by a contractor. Greenhouse Megastore can also provide an erected price.

These hobby greenhouse kits, special ordered from their UK factory, have a 90 day lead time, and require full pre-payment prior to shipping.
