Every window in the greenhouse is salvaged. The rows of windows on the broad side were a free score on craigslist. The doors were street finds, and most of the cobbled-together gable sides are made from windows we found at local salvage shops, or made from sheets of recycles plastic.
The foundation was dug and laid by hand
Careful siting gave us the full benefit of all the available sunlight at Mellish Fields West.
Shelves were built along the broad walls for working, and for all of the little seedlings which will live inside the greenhouse for their first weeks. The back deck brings you into the garden and offers a sunny place to sit.
In the future, we intend to add a layer of plastic sheeting along the underside of the rafters to help keep the heat in. As it is, we can count on the greenhouse being dry and significantly warmer than it's surroundings. Time will tell how our plants will like it.
