The Story Of Alpine’s Origins

Eldon about his 10′ x 12′ Kit


“The assembly was straight forward and the greenhouse has exceeded my performance expectations. I’m amazed how it captures the solar heat even on a very overcast winter day. This design is well engineered and the product is a pleasure to use. I highly recommend it.”

Shauna about her 10′ x 16′ RTG

“ I’m not even sure where to begin on how much I love this greenhouse. I could talk your ear off about the function and design and how each little detail has been thought through in-depth. But for my family, this sturdy little structure is so much bigger than it’s four walls. It’s our place to create, relax, to dream of warmer days in the middle of February and yes, the place where we grow our food. It’s also the first stop for almost everything in our little CSA startup, Good Mama Farm, be it seedlings or full-grown tomatoes. It floors me every time I walk through the door that this little work-horse can provide so much to so many.”

Bob about his 10′ x 30′ PSG

“Viv and I started collecting materials to build our own energy efficient greenhouse, when we saw one of Alpine’s assembled units. Alpine designed and built a greenhouse that used methods and materials that were tried and tested, much better than us doing it from scratch! They installed a ground based geothermal system in ours that lets us operate year-round with minimum energy inputs.”

Josh about his 12′ x 16′ Kit

“On December 15th, 2021 Colorado Springs, Colorado got record breaking winds in excess of 96 mile an hour gusts. As sad as it was to lose so many beautiful old trees blown over in our city, I was very happy that our Alpine greenhouse stood without any damage. During the storm I was of course very concerned about the greenhouse, and maybe not the smartest thing on my behalf, I stood in it to see its structural integrity. I was amazed that it was as sound as my house. As I stood there watching I observed my neighbors 85′ blue spruce topple on to the roof of his house, and of course I ran to help my elderly neighbors. Thanks you AlpineGH for walking me through this build!”
