Greenhouses, sometimes referred to as glass houses, hothouses, or conservatories, are sanctuaries where temperature and lighting conditions are ideal for plants to grow, regardless of the outdoor temperature. If you’re an avid gardener, the idea of having your greenhouse in your backyard may sound like heaven (and if you’re not such a green thumb, a little getaway outbuilding of your own may make a gardener of you yet). The cost of hiring someone to design and build a greenhouse for you, however, can be prohibitive. These DIY greenhouse plans can help you to build your own expertly designed plant sanctuary while keeping budget in mind.

There’s a lot that drew us to these greenhouse plans: For one thing, the building is sleek and cute as can be. The designers drafted the plans with gardeners, not carpenters, in mind and reviewers say the plans are easy to follow. Though the downloadable PDFs come with materials lists, cut lists, and all of the expected instructions, A House Made Designs makes no plan for the door—they encourage DIYers to reclaim one. If all of this doesn’t make the prospect of this build exciting enough, how about a footprint that can be modfiied to be as small as 10 feet by 8 feet, and as large as 10 feet by 24 feet? Let’s get building!
