Lumen & Forge is a multi-disciplined company with expertise in immersive technology. They are experts in creating spaces for entertainment. With a beautiful Geodesic Dome, be ready to be amazed.
There are many advantages to using a Geodesic Dome structure to house your outdoor needs. Whether it be a greenhouse to extend your growing season or a cozy sunroom to read and relax in the backyard, these Domes will surely be a nice addition to any application. They're stylish, strong, and durable while maintaining a functional outdoor structure that provides shelter from nature's harsher elements while allowing all the visual advantages of being in those elements.
The geodesic design works to have more efficient and uniform airflow throughout the structure while keeping temperature levels stable and maximizing solar gain. Their unique shape allows for easy assembly while also creating a structure that can withstand most inclement weather. With a minimal amount of flat surfaces, rain, wind, and snow can easily move off the cover without building up. The unique design also creates even weight distribution allowing the frame to be extremely stable. This allows items such as lighting or decor to be hung or fastened to the frame without issue. With 3 sizes available, we are sure you will find them suitable to fit your outdoor needs. Get yours today!

All of the domes come with a detailed manual displaying step-by-step instructions on how to assemble the dome properly along with cover care info. When choosing the location for your Dome, it’s suggested to pick a location that is protected from the wind. While a base isn't required, we strongly recommend that the Dome be anchored to the floor (wood deck/cement/dirt) with included anchoring plates. Anchoring hardware will need to be purchased separately to best suit the ground type of the location it will be installed on. More info about floor anchoring is listed in the manual.

Free curbside freight delivery
Choose your size, color and options. Your greenhouse ships from the manufacturer's warehouse, packed for freight.
We'll contact you to set up a delivery time frame that works for you.
Delivery is by LTL motor freight on an 18-wheeler. Let us know about tight roads or low wires so we can plan ahead.
Someone needs to be there to receive the delivery. The driver does most of the work but may need a hand.
Foundations and bases are bulky, so we recommend ordering them together with your greenhouse to avoid a separate freight charge.
