Our "Down in the Dirt" review
The Riverside is a greenhouse that will not overwhelm your back yard with it's presence. It has a sleek, transparent look that allows it to blend in nicely with any landscape no matter how big it is. This greenhouse offers class spelled with a ā€˜gā€™. The very clear glass sides are elegant and high for maximum use of space inside. The poly roof is able to resist the rain and hail, falling tree limbs, and sailing baseballs. I can just picture a miniature fruit tree inside on of these little beauties.


One of America's finest greenhouses! The Riverside models are built according to a modular design, making them sturdier, heavier, more elegant looking, and easier to assemble. All are upgraded to crystal clear tempered-plate glass sides 3/16" thick and set in Butyl, and the roofs are made of durable fiberglass (also available in double-wall polycarbonate). The result is a completely finished panel that should last for generations. The upgraded French door adds a classier look, and the side and roof vents will provide your plants with fresh circulation.

San Bernardino greenhouses are used in schools and universities throughout the United States where quality and durability are required. Redwood is the perfect material for a greenhouse, unsurpassed as a garden structure, and ours is precision milled by skilled craftsmen. The Riverside model is shipped as a kit that you assemble, but is also available in pre-built panels that are very easily bolted together.

Greenhouse Frame:
Redwood is resistant to weather, insects, decay and should last a lifetime with no special treatment. There is no finer or more beautiful wood available for a greenhouse. San Bernardino frames are made entirely of specially selected kiln-dried redwood and are bolted together for strength and stability. The redwood will never rust, corrode, crack, or require painting and is unaffected by changes in temperature.  Our standard models greenhouses are all clear or better California redwood with all parts pre-cut; all drilling done here at our factory.

Easy Assembly - You’ll be greenhouse gardening in no time:
This greenhouse’s all bolt construction makes it easy to assemble for two people with just an adjustable wrench, Philips screwdriver, hammer and ladder. Everything comes from the factory with all parts precut and pre-drilled and all hardware is sorted for your convenience. It usually takes two people two to three days to put it together.

Extensions Available: (a greenhouse that grows with you)
As your horticulture hobby grows, so can your greenhouse. All models of the Standard greenhouse can be extended in length with four foot redwood sections of the frame. Simply unbolt one end, bolt in the extensions, put the end back on and your greenhouse can grow with you. The seven and nine foot wide models can be extended up to 20 feet long and the 14 foot wide model can be extended up to 24 feet long.

Optional Redwood Benches:
We strongly recommend adding the  redwood bench option to  increase your growing area. Benches for the seven foot wide model are 28 inches deep and 30 inches high while benches for the 9 and 14 foot models are 33 inches deep and 30 inches high. All benches are sold in pairs.
