These beautiful greenhouses made from old windows prove that your dream greenhouse doesn’t have to be costly. Most gardeners dream of adding a greenhouse to their garden space, and for good reason. Greenhouses are ideal for starting seeds early in the year, for extending the growing season in cold climates, and for the beauty they bring to a property.
Greenhouses can be costly to build, however, which leaves many DIYers looking for inexpensive alternatives. One way to cut costs when building a greenhouse is to use as many recycled materials as possible.
Glass and polycarbonate panels are the most expensive components in a greenhouse. Fortunately, old windows are abundant just about everywhere and can be found for cheap or free with some searching.
When you consider how many glass windows and doors are disposed of every time a building is torn down or remodeled, it makes perfect sense to seek some out and reuse them in your greenhouse.

15 Greenhouses Made From Old Windows
The blue greenhouse
This homeowner salvaged old windows and doors from neighbors who were replacing theirs. She built her own trusses and painted the wood and window frames blue before putting everything together. Her husband and son assisted in the framing and window installation, and the result is absolutely beautiful.
The family loves how their greenhouse turned out so much, they also use it as a “happy hour hangout”. Via Fine Homebuilding

One of my favorite greenhouses made from recycled windows is this one, which we featured in an earlier article. This couple used reclaimed windows and wood pallets to build a functional and practical greenhouse.
It is the centerpiece in their garden and is used to grow flowers and climbing vegetables, overwinter annuals, and even serves as a shelter for their chickens and quail. Not too shabby, huh?

11. Greenhouse framed with pallet racking
While using reclaimed windows for a greenhouse is great, using recycled framing materials makes it even better! Jason Ellis of South Carolina used pallet racking he found for free on Craigslist as the frame for this beautiful greenhouse.

Lastly, here is a gorgeous greenhouse with an attached cold frame. Barb from Our Fairfield Home and Garden found three antique windows at a yard sale and from there, an idea for building a greenhouse from old windows took root.
