This first-rate structure offers the highest quality perennial gardening for those who prefer a smaller garden house. The 8′ x 12′ has 4 air vents (on the roof and the base) that permit maximized cross air circulation for a controlled air climate. All garden houses are made with the finest materials, crafted for efficiency and excellence. The redwood frame is specifically chosen because it is heat efficient, organic, and extremely sturdy in standing up against the elements- resisting the 100 m.p.h winds of Hurricane Floyd. The roof and wall panels are made with an indestructible polycarbonate glazing which insulates and diffuses sunlight efficiently (you’ll save 40% of the cost of heating a single-pane glass greenhouse). In addition, the roof has a 45-degree slant to capture more light during those short winter days when the sun is low. With a recycled plastic base, which looks like wood, there is no need to worry about its durability because the base is fungus and insect proof. The only tools necessary are a 6′ ladder, a tape measure, and a power drill.
