Lunaria Greenhouse Sizes

The Lunaria Walk-In Greenhouse Collection is designed for small backyards, narrow side yards, urban gardens, and other spaces where a 10-foot-wide greenhouse may not fit.

Available sizes:

Lunaria’s 6.5-foot width makes it easy to fit into compact residential spaces while still providing the height and room of a true walk-in greenhouse.

The arched design offers good headroom and helps rain and snow shed naturally. UV-protected double-wall polycarbonate provides durability, light transmission, and insulation, with 4mm standard panels and an optional 6mm upgrade.

Built for Wind & Snow

The Lunaria Walk-In Greenhouse is designed for dependable performance in changing weather conditions. Its reinforced galvanized steel frame and arched roof provide additional stability while helping snow shed naturally from the roof.

• Wind resistance: up to 65 mph
• Snow load: up to 42 lb/ft² uniformly distributed
• Reinforced galvanized steel frame
• Arched roof helps reduce snow accumulation
• Ground anchors included for secure installation
• Suitable for year-round use in many northern climates

For best performance, the greenhouse should be properly anchored and installed on a level foundation, and excessive snow accumulation should always be removed when necessary.

I would place this section right after “UV-Protected Double-Wall Polycarbonate” because wind and snow resistance are strong purchase-decision features.

Inside, the narrow footprint works well with a central walkway, raised beds, containers, shelving, vertical growing systems, and seed-starting areas.

Lunaria is supplied as a DIY greenhouse kit and is ideal for vegetables, herbs, flowers, seedlings, season extension, and overwintering plants.
