Cottagecore Goals

With a kit greenhouse, you put all the pieces together yourself and reduce costs. Ready-made plans are downloadable blueprints for building your own greenhouse based on someone's tried-and-true design so there's no guesswork — or waste — in buying materials. We've rounded up the best DIY greenhouses so you can build without breaking the bank. Get growing in style with these homemade greenhouse plans.

First up: It's the Dutch door for us. This little 4' x 8' greenhouse is so stinking cute. And the designer, Sara Syrett of Etsy shop Twelve on Main, designed these plans with a budget in mind as the list of materials and step-by-step instructions were created with as few cuts as possible, which results in less waste.

Modern Chic

Black metal finishes are having a huge comeback, and we love this 8' x 12' black-frame greenhouse for a modern mountain home or a modern farmhouse backyard. The building plans from Etsy shop A Home Made Here don't include plans for a door, leaving it open-ended for you to find a cool salvaged wood or vintage door.

Heavy on the House

Some neighborhoods and homeowners associations have strict rules about backyard structures and the number you can have. And even if you don't live in a subdivision like that, you may not want a bunch of different structures in your yard. This greenhouse design from Etsy shop Wood Plans is half greenhouse and half shed, combining space for plants, pots and all your tools. And because it's only half a greenhouse, it looks more like a mini accessory dwelling than a glass onion in your backyard.
