Royal Victorian™ 10X9X15.ft VI34 Greenhouse

Store in a dry, protected place, away from sunlight, rain, and moisture.

If storing outdoors, cover securely with a waterproof tarp.

Avoid moisture or condensation inside packaging to prevent corrosion. Handle the glass box with care—it’s heavy and fragile.

Always follow the safety instructions on the glass box sticker.

Technically, yes—but not without some important modifications. Greenhouses are built to function as greenhouses first, which means they’re not naturally water- or air-tight. Plants rely on constant airflow, so the structure is designed to breathe. To make a greenhouse more suitable for occasional living use, you’ll likely need to add extra sealing—especially around the roof panels and glass. A good silicone sealant is often necessary if you want better protection against rain.

Because the greenhouse uses single-pane glass, condensation is common. Moisture can collect on the inside and drip, so it’s best to stick with indoor/outdoor furniture and avoid placing valuable electronics or fine wood pieces inside unless they’re well protected.

Keep in mind that the roof vents have automatic openers. During a warm rainstorm—anytime temperatures rise above 70°F—those vents may open on their own, letting water in. You can switch to manual openers if you’d prefer full control.

Temperature control is another challenge. On sunny days, glass greenhouses heat up quickly, and depending on your climate, managing summer temperatures can be a constant battle from late spring through early fall.

People have converted greenhouses into extra living or lounging areas, but it requires thoughtful customization. Additional sealing, climate control systems, window tinting, and proper heating are all part of making the space comfortable and functional.

If you want a milky appearance that you can’t see into/out of, then a full poly would be the thing. However if you want to see through it, then you should do glass. 

UV/Heat block poly is designed to keep down the heat gain on sunny days whereas a glass greenhouse would heat quickly – so this may also depend on state and what your weather challenge is there.

A Janssens greenhouse can be a beautiful, boutique setting for small weddings, elopements, photo sessions, and intimate events. However, it is very important to understand that it is designed as a greenhouse for plants, not as a purpose-built commercial event hall.

On sunny days it can get very hot, and on cold nights it will need heating, so you’ll likely need extra ventilation, shading/heat-block film, and climate control to keep guests comfortable.

For any commercial use (weddings, paid events, photo sessions), you must check with your local building and zoning authorities about permits, occupancy limits, fire safety, and other legal requirements. The greenhouse is not certified as an assembly building, so any use as a venue is a custom use at the owner’s responsibility.
