Custom Four Season Greenhouses

Cedar beams are the most common option for backyard greenhouses, they are beautiful, long lasting and economical.

Naturally rot resistant, our Cedar beams are preserved with natural penetrating oils and a hot wax seal.

"Toe-nailed" to the ground with 1/2" rebar and seated on pea gravel for drainage.

Formed concrete piers and cedar beam foundation provides the strongest beam system for high wind locations.

Piers are excavated to the minimum frost depth and the Cedar beams are attached with concrete anchor bolts.

A footed concrete pad provides a seamless flat floor and the durability of modern house foundation.

With moderate excavation and minimal forming, this is the most economical concrete foundation option.

A footed concrete wall requires extensive excavation and complex forming yet provides the most benefit to a winter production greenhouse.

With the ability to insulate the ground from freezing, this foundation is the most effective option for a completely passive greenhouse design.

A floor that is open to the earth allows for gardening (row crops) directly in the soil. 

This is most commonly found in medium to large greenhouses but can also be adapted to a small design.

A chipped stone floor allows for maximum drainage in a greenhouse and is an great way to add passive heat retention.

We always include a wood pathway for ease of movement, convenience and safety.

Our greenhouses are easily adaptable to be ADA compliant.

Concrete pavers are a convenient way to create an aesthetic living space for furnishings and entertaining.

This type of floor is ideal for hydro and aquaponics equipment and supplies.

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

We utilize Douglas Fir lumber for its strength and longevity.

Wood is easily adaptable to building code to create a safe and compliant structure.

We build our timber frames with timber joinery for maximum strength and preserve the wood with penetrating oils and beeswax seal.
