Sunshine DIY Gardenhouse Kit 8 ft. Wide with 4mm Twinwall Polycarbonate Panels and Redwood Frame

Sunshine GardenHouse greenhouse kits are designed for easy assembly while delivering commercial-grade performance for hobby growers. Crafted in the U.S. from all-natural redwood, these beautiful greenhouses come with a range of premium features not typically found in other kits. As part of the Mt. Rainier series, these eight-foot-wide structures feature a sturdy redwood frame and twin-wall polycarbonate panels for the roof and siding. For those who need more growing space, an optional extension kit allows the 8' x 12' model to expand by an additional four feet.

Each GardenHouse backyard greenhouse is built for convenience and efficiency, featuring four vents with automatic openers and lockable Dutch doors for secure access. With up to four optional benches, you can maximize your growing area for crops and seedlings. The base, made from recycled plastic, eliminates the need for a foundation and is designed to resist rot over time. Assembly is straightforward with pre-assembled panels, step-by-step instructions, and an instructional video, making it possible to set up your GardenHouse in less than a day. Additionally, an optional 39-inch-wide wheelchair-accessible door is available for added accessibility.

Engineered for durability, the Sunshine GardenHouse is wind-tested to withstand speeds of up to 80 mph and features a 45-degree roof pitch to prevent snow buildup. The naturally rot-resistant redwood frame requires no maintenance and is built to last for decades. Its 4.5mm twin-wall polycarbonate panels are UV-treated and provide up to 250 times the impact resistance of glass. Strong zinc-plated metal connecting brackets secure the greenhouse sections together for long-term stability. Auto-opening roof and side vents ensure optimal temperature control, and an optional door can be installed at both ends at no additional cost.
