Three Season Greenhouse

The gothic arch design allows for snow to easily make its way to the ground allowing light to enter your greenhouse during winter months.

Our cedar beam foundation is a stable and rot-resistant base for the greenhouse frame.

Custom manufactured brackets and 3/8" hardware secure the greenhouse together into a secure and strong structure.

Wood frames are our specialty and they are a sustainable and aesthetically pleasing material for a greenhouse.

We utilize Douglas Fir lumber for its strength and longevity, preserving the wood with penetrating oils and a hot wax seal.

Poly film greenhouse covers are the most economical choice; but don't let the economy of the product underpin your greenhouse.

We choose to use an 11 mil woven, ripstop, impact resistant and UV stable product that outlasts other greenhouse films by leaps and bounds.

This material will last a decade or more and resists the Colorado hail that decimates inferior products.

Included are wall vents that allow cool air to enter the greenhouse utilizing "univent" automatic openers.

Included are roof vents that allow warm air to exit the greenhouse utilizing "univent" automatic openers.

The automatic venting system allows cool air to enter low on the wall, with hot air exhausting through the upper roof vents.

All the vent windows utilize "univent" non-electric openers.

A chipped stone floor allows for maximum drainage, works well with container gardening and increases heat retention which extends your growing season.

Weed barrier is installed under the gravel.

Wood pathways provide ease of access through your greenhouse as well as being adaptable to ADA compliance.

End wall ventilation fans exhaust hot greenhouse air and require electric to be installed for operation.

This option is best used only on large greenhouse structures.
