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.

Natural Wood Vibes

If minimal, light wood is your aesthetic, take it outside with this design from Etsy shop Good DIY Plans. And if you're doing an entire backyard makeover, they have building plans for everything you could possibly need in a garden, from box planters to tool sheds to patio furniture so everything will match and coordinate.

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.

An Efficient Lean-to

Shopping for DIY greenhouse plans online can feel a bit risky, especially if a designer doesn't list materials upfront. That's we why love Etsy shop The Hillside Market for disclosing a rough budget for each greenhouse design as well as an estimate for the time needed to construct and skill level. This 7' x 10' greenhouse, called Petunia, is labeled for the novice DIYer, takes about a weekend to finish and costs just over $1,000.

An Efficient Mini Lean-to

We also had to include this smaller version from The Hillside Market: Sweet Pea. This 2' x 4' greenhouse is doable over a weekend for one person. The total cost of materials is under $400, making it a great budget greenhouse.

Plant Barn

Why have a greenhouse when you can have a green barn!? This massive 10' x 12' design is perfect for veteran gardeners ready to take their veggies to the next level. With this kind of space, you'll have room for seed starters from every summer produce imaginable.

Victorian Dreams

There are greenhouses and then there's this design from Etsy shop Mama Potrafi. It's gorgeous and it's so clever. Buying a traditional, Victorian-style greenhouse can easily cost more than $20,000, but this plan shows you how to semi-hack the look with upcycled windows, doors and a can of paint.

She Shed Greenhouse

A greenhouse is a utility, but it can also be an oasis. This she shed from Etsy shop Mireland blurs the line between accessory building, greenhouse and sunroom. With nearly floor-to-ceiling windows on three sides of the structure, you'll have plenty of space to keep plants sun-drenched and toasty. But the back wall is perfect for some outdoor furniture or yoga space.
