It is states up front that in order to build this greenhouse for around $50 it will take some upcycling and scouting of free items on your part.

This greenhouse is built for less than $100.

It has an all wood frame and uses old windows for the walls.

It add a bit of a rustic touch but with a little paint could be transformed into a great attraction on your homestead.

The wooden frame makes it a sturdy build and the windows offer great insulation.

The website does offer instructions along with a list of materials needed to make constructing this greenhouse easier.

They added some great repurposed shelving inside and did it all for around $67.

You can’t beat that price for a fully functional greenhouse.

This design is a little different from the others mentioned. It has a round formation. It is very simple to build and is less complex than most.

It requires very little tools but the tools that are needed are listed along with the plans. Most people that build this form use it in a cold frame fashion. You can add grow light to it if you choose, though.

This is the type of greenhouse I have on my own homestead. You can read all about how we built ours for less than $200 on the very bottom of this page.

If you are looking for an inexpensive option, this is a great fit.

The Big Greenhouse

The ‘big’ greenhouse is going to be a large 10×16 structure. These plans are very basic but would certainly do the job.

This greenhouse is a simple A-frame structure. It is a personal preference, but you will probably have to build shelving or above ground beds inside of it. However, you could just plant directly in the ground if you choose.

With these plans, you will have plenty of room to decide how you want to lay out the inside of the structure. You will also have ample amount of room to grow almost anything your heart desires.

The 5-ft.-high knee-walls in this design provide ample space for installing and working on a conventional-height potting table. The walls also provide some space for plants to grow. For a door, this plan simply employs a sheet of weighted plastic that can be tied out of the way for entry and exit.

The ‘Barn’ Greenhouse

This greenhouse gets its name honest. It is shaped just like a barn. Its appearance is one that will fit right in on any homestead.

The site includes all plans (all for free) on how to construct this greenhouse. It also includes a list of all tools.

Ana does advise that you read everything over thoroughly before jumping into building. It is nice that the medal slabs that are used for the side do not have to be cut to fit the sides. You can just throw them right up!

From the looks of it, this greenhouse would be easier to build and look great to boot.

GeoDome Greenhouse

It is a circular shaped greenhouse and very interesting to look at. Since this greenhouse is a circular shape it makes it better for withstanding high winds.

The plans and tool are available, along with pictures of this project being built.

This appears to be a really cool greenhouse. It is said to have the most growing space in comparison to most any other greenhouse available.

The only thing I notice when looking at the project being built is that it is a great option for those with great carpentry skills. It does not appear to be for first-timers.

This greenhouse looks really cool. There are no other words for it.

It has windows on top that can be opened when ventilation is necessary. It also includes a door in the front and back as well.

These features can be optional, but they are great features so if you can add them I would recommend it.

These plans are also free. They do not include pictures of the building process like some of the others that I’ve mentioned.

So be sure that you read them thoroughly before jumping into this project.

If you hate or love plastic bottles, this greenhouse is for you. This is another greenhouse that could be potentially free if you know where to look for the materials.

You can shape it in any form that you wish. They show pictures of a typical A-frame greenhouse as well as a hoop greenhouse too.

There are no actual plans but certain tips are offered since the building process is rather self-explanatory.

It is important to keep the bottles lined up so your walls are even.

This greenhouse should work effectively for any need you might have. You should also have ample amount of growing space.

The IDEA Donna Greenhouse

The IDEA Donna Greenhouse

This greenhouse is a great greenhouse for the beginner.

It has a strong wooden frame that should help it to last. While also being simply built.

The plastic sides still allow for ample amount of sunlight to get through while still holding heat in during the colder temps.

The person that wrote the instructions on this greenhouse actually got the idea from another blog. The only problem was there were no instructions.

She fixed that problem by building this greenhouse from those pictures and creating very detailed instructions (and pictures) for those that want to give it a try.

The details are all there, the functionality is there, and the budget is on point too. If you are working on a tight budget and in need of a greenhouse, this could be the one for you.

This is another budget friendly greenhouse idea.

It is actually a smaller greenhouse. The purpose of it is to encompass small potted plants.

It has a hoop shape design that is constructed mainly of PVC pipe and plastic. The building materials are what make this such an inexpensive design.

The site offers very detailed instructions on how to construct this greenhouse and a detailed list of all materials needed.

This greenhouse could help those needing it for only a few plants. You could also build a multitude of these greenhouses in the place of one larger one as they are mobile.

The Tomato Fort

The Tomato Fort

This greenhouse costs about $50 to build. This is not a kit.

It requires different materials to be purchased and put together to build this little greenhouse.

The reason it is named the tomato fort is because the person that designed this intended it to protect her tomatoes from a lot of rain.

Tomatoes do not like rain. It is actually better to water them from the ground.

So she built her tomatoes a little fort that can be opened on the sides during prettier days and closed on rainy days.

It is a hoop construction that is mainly made from PVC pipe and plastic.

The site provides a list of all the materials needed and detailed instructions on how to build. It says that it only takes about an hour to construct.

The Basement Greenhouse

The Basement Greenhouse

This is another really awesome greenhouse. If you have a basement, this is the greenhouse for you!

You will actually construct the frame right outside of your walk-out basement door. This allows you to walk straight from your home into your greenhouse.

Pictures of the build are available as well as instructions on how to build it. From the pictures this is a very functional greenhouse. You cannot plant directly into the ground.

However, you can start many seeds on shelves inside this greenhouse. You could also plant produce in pots and grow them year round in this greenhouse as well.

The Garage Greenhouse

The Garage Greenhouse

I called this one the ‘Garage Greenhouse’ because it kind of works like a garage. It is actually a very original and unique design.

You place all of your plants up against your house. You can even create a little garden next to your house and add some shelving for your potted plants.

Let them grow in this convenient spot. However, when it gets cold you’ll have a greenhouse that can be pulled down over them.

This is obviously a cold frame style greenhouse but is really neat that it can be folded back when it is not in use.

This would be a great option for someone with a smaller yard that may not want a greenhouse freestanding all year long and taking up unnecessary space.

The Storm Windows Greenhouse

Maybe you aren’t looking to grow mass amounts of food in your greenhouse. Maybe you just want to prolong a plant’s life or start a few seeds.

No worries. We have not forgotten you. This is the greenhouse for you. Another great thing about this greenhouse is that is can be fairly cheap.

It is built out of old storm windows. If you have a second hand home store in your area, you should be able to find the materials at a reasonable price.

If you’d prefer to go with brand new windows, you can do that to. She provides pictures, plans, and all of the items you will need to build this little beauty.

This greenhouse is a lot like the previous one. However, it uses all old windows.

This is a great option for someone looking to build a smaller greenhouse without a lot of cost added to it.

You can make this greenhouse larger if you choose. All of the plans are available and the tools listed with them that you will need in order to construct it.

I love this greenhouse because it is very quaint looking. It could also potentially be free to build. You can find old windows on sites like Craigs List for free at times.

The Trampoline Greenhouse

The Trampoline Greenhouse

This is probably one of the coolest upcycled greenhouse projects you’ll ever see.

They literally took an old trampoline and turned it into a greenhouse.

The trampoline frame is pulled into and one part is used to shape the front while the other half is used to shape the back. They then cover the greenhouse in plastic.

It is very inexpensive and a great way to repurpose that old trampoline that the kids never jump on anymore.

As an added bonus they give lots of great tips on how to keep the temp up in the greenhouse. One way is they spray painted bottles black and filled them with water.

During the day, the black draws heat and warms the water.

At night the water is disbursed and keeps the temperature up in the greenhouse.
