40 Foot Dome Greenhouse Build Specifications & Details
The 40 Foot Dome greenhouse kit from KingDome Greenhouses is big enough for serious growers who need honest-to-goodness production space. With 1,256 square feet of floor area, the versatile 4V frame provides 11 to 12 people with space to grow fresh fruits and veggies at home. You’ll get treated wood framing, heavy-duty connectors, standard vents (x2), and your choice of greenhouse covering and doors for the starting price of $23,300. If you’re in the market for large greenhouse kits, the 40 Foot KingDome strikes a nice balance between hefty and manageable: bigger than any backyard hobby greenhouse, but much easier to site and handle than a monster 50 or 60-footer.
What Kit Is the 40 Foot KingDome?
The KingDome 40 Foot is a 4-frequency geodesic greenhouse kit framed with sturdy wood. The 4V Low Profile Dome reaches an interior height of 14 feet 6 inches, while the standard model (also known as the 4V) reaches 20 feet. Both greenhouses come with either a 2 or 3-foot base. In all models, the base is made with eco-treated 2x6 framing. All structural struts are treated 2x4 lumber. Standard hubs are heavy-duty connectors, with the option to upgrade to Super Duty Hubs.

Covering Options & Setup
Prices include shipping to the contiguous United States and expert engineering & design. Foundation, landscaping, greenhouse covering installation, installation supervisor, tools, and setup & breakdown fees are extra. Contact KingDome to discuss custom configurations.
12 mil interwoven reinforced polyethylene is the standard greenhouse covering. For better insulation, choose a dual polyethylene covering or a hard-sided plastic covering known as Solexx polyethylene. Poly comes in multiple thicknesses, while Solexx ranges from 3 to 5 mm thick.
Once you pick the structure’s covering, consider how you’ll install it. Prices do not include assembly or installation. You can install the greenhouse yourself (a popular DIY choice), hire a KingDome supervisor to oversee your crew, or hire KingDome’s full installation crew. Published prices list $5,400 for installing a 40-foot diameter greenhouse. Keep in mind these are estimates and your final bill could be higher or lower depending on your property and needs. Shipping and delivery charges apply separately for Alaska or international destinations.
Who Should Buy The 40 Foot Dome Greenhouse Kit?
The 40 Foot greenhouse kit will cover the growing needs of serious home growers, homesteaders, and small farms. This geodesic greenhouse kit would also work well for community gardens and commercial greenhouse businesses. If the 706-square-foot 30 Foot Dome feels too restrictive for your growing ambitions, but a 50 Foot greenhouse feels downright industrial, King’s 40 Foot model sits right in the sweet spot for feeding 11 to 12 people.
