I had wanted a greenhouse for quite some time, but it wasn't until I had a "side line" website selling yard structures (gazebos, patio covers, carports and greenhouses) that I decided to buy one myself. I bought one made by the Sunshine Gardenhouse company out of Washington State, USA. It is one of their Mt. Rainier Series measuring 8' x 16' and made from Redwood with Polycarbonate Panels. At it's peak, it is 10' tall, has two Dutch Doors and two Roof Vents. As a retailer for them, I was able to get it for wholesale.
While it is well-made and I have enjoyed this greenhouse for the past 2 years, if I knew then what I know now, I probably would have gone a different route. I really wanted the greenhouse to extend our growing season in the Fall right up to the very cold weather and start off as early as I could in late Winter again...in other words, at least a 10 month greenhouse. Unfortunately, I really knew very little about greenhouse insulation and heating and taking advantage of solar energy and thermal mass. As a result, I have started making many modifications and will continue to make modifications as time goes on.
The day it was completed and relandscaped:
