Known for its functional design and natural beauty, the Sunshine Greenhouse is not only easy on the eyes but on the gardener. Their greenhouses come standard with redwood framing (a natural insulator!); Dutch doors that provide extra ventilation, peaked roof for extra head room, and automatic vent openers. Construction takes only hours with only basic tools required. Sunshine greenhouses can be just as easily expanded later on. The base is made of recycled plastic and consequently fungus and insect proof.
