10 Free Greenhouse Plans
10 Free Greenhouse Plans
Here in Louisiana we call it Lagniappe [lanˈyap]. It’s a little something extra……for free! Everyone loves free. I get asked all of the time how to build your own greenhouse. So, today I have gathered together 10 free greenhouse plans for you. Not everyone can afford or needs a glass greenhouse kit. Tom and I have reviewed the plans and have added our comments to each. These comments are based purely on our years of experience building greenhouses. We have not received any compensation of any kind from any of these plans. So, enjoy and get busy building a greenhouse this week. Please keep in mind that as far as we know no engineers were involved in these plans. In other words, we do not feel that any of these plans have been built with heavy snow and/or wind loads in mind. Also, as a general note: A lot of the plans mention using plastic sheeting that is not UV protected. Don’t expect any more than 1 years use out of non UV protected plastic. We always recommend using 6 mil, 4 year polyfilm to cover greenhouses. With the appropriate waivers in place, let’s get busy building!
California Style Roof Greenhouse
California Roof Style Greenhouse Plans – We used to sell and install sunrooms. That is how we really got started with greenhouses. Anyway, we used to sell a sunroom that looked like this and it was called the California Roof Sunroom. These plans seem very thorough. They even tell you how to square up your base. It is a bit distracting to try and read the plans on their website due to all of the ads, etc. But, they do offer a downloadable set of plans (ad free) for $5. Might be nice to have these to take to the jobsite.
YellaWood Greenhouse Plans
YellaWood Greenhouse Plans – These plans are from the manufacturer. They do give you a lot of specifications about the building materials, but the plans are pretty much a line drawing with measurements. If you are an experienced builder, you probably would not have much trouble with this. If you are a beginner and need more detailed instruction, this might be one to pass on.
Barn Style Greenhouse Plans
Barn Greenhouse Plans – They state one weekend for this. I am a bit skeptical of that time frame. This greenhouse has a lot of miter cuts and will require what seems like a lot of fitting to me. But hey, who can resist the looks of a barn style greenhouse?
Raised Garden Bed with Removable Cold Frame
Raised Garden Bed with Removable Cold Frame – This is a super plan and will work nicely along side of a standard garden and greenhouse. They are stating a 10 – 15 degree increase in temperature inside the cold frame. This is a great project for someone with limited space, or someone who just wants to get a head start on the garden.
300 Square Foot Hoop House
300 Square Foot Hoop House – This is a well thought out design and plan. I do however have a couple of issues with his recommendations. First is to use landscape cloth as a shade cloth. Why wouldn’t you just use a shade cloth that is made for greenhouses? Also, this is a little bit large not to have a ventilation system. I think a couple of roof vents and a ventilation package would make this greenhouse a whole lot more useable in the warmer months.
Attached Greenhouse Plans
RunnerDuck Greenhouse Plans– I really like the looks of this greenhouse, although I am wondering what it would look like with a small overhang on the roof on all sides. He has stated that you can adapt this to make a freestanding greenhouse with these plans as well. I do like the dutch door feature and the fact that he used a roof vent with an automatic opener.
Bamboo Greenhouses Plans
Bamboo Greenhouse Plans – What a great way to use bamboo! I would suggest using batten tape also when securing your film to your frame. I am not really crazy about using a door that is secured with velcro. If you are in a high wind area I would think this would give you problems. Other than that a great simple plan.
GeoDome Greenhouse Plans
Geo Dome – This may not be for a beginner. Lots of angles to cut for the frame to fit together properly. But, who doesn’t love the look of a dome greenhouse? Sounds like they did a whole lot of research before designing this. If you have some skills and time I would consider this plan.
$50 Greenhouse Plans
$50 Greenhouse – Of course this is if you can recycle a whole bunch of materials. But, he states that even with new material you can build this for around $200. If you are in an area with high snow be sure to look at the picture of what happens when you get a couple of inches of wet snow. His greenhouse collapsed. So, I would definitely rule this one out for snowy areas.
10 x 16 Greenhouse Plans
10 x 16 Greenhouse – These are nice plans. I think he is very realistic when he gives a one week time frame on building this. I would suggest a ventilation system and roof vents with a greenhouse this size. He mentions covering it with polyethylene/foil sheets. I am not really even sure what this is. I would recommend using 6 mil, 4 year greenhouse polyfilm.
In closing, my first, and second greenhouses were both ones that we built ourselves with our own plans. They were both covered with clear plastic (non UV) film. We did not know where to get the UV protected film at that point. One year is the life expectancy of the non UV material. I wish at the time we would have known the difference, but we just kept recovering. Also, not to tell tales on myself, but at the time we were building these greenhouses there was no internet and no free plans. What a help that would have been! Most of these plans are from individuals who have taken their time and energy to supply these plans for us. We thank them for their help.
Product Review – America’s Best Polycarbonate, Best Buy Lean to Greenhouses
Today we are going to do a product review of one of the greenhouse kits that we offer. The America’s Best Polycarbonate Greenhouse and the Best Buy Lean to Greenhouse are basically the same structure, just one is freestanding and the other attaches to your home or a building. These both offer what we feel is the best “bang for your buck” in a greenhouse Made in the USA. They offer quality materials and excellent pricing.
The frames are made of 6063-T3 aluminum with a powder coated finish. This high grade aluminum gives the frame strength and durability. The standard colors are white, brown or green, but fear not, we can custom match the color of your home, your favorite sports team, just your favorite color. The stated wind and snow loading are 70 MPH winds and 23 pounds per square foot snow load. All framing is assembled using stainless steel T bolt and stainless steel lock nuts. This frame also has a 10 year warranty against damage due to faulty materials.
The greenhouse is glazed with 6mm clear twinwall polycarbonate. The polycarbonate sheets have a 10 year warranty that they will not vary more than 6% in light transmission in 10 years. This is a fancy way of saying that this material will not yellow, get brittle or break. Actually, I have personally seen this same material in use past 15 years. I have heard reports back from people in the industry who have seen this material in good usable condition up to a period of 20 years. There is also a 10 year warranty against hail damage. Some people do not like the twinwall polycarbonate because of the view through it. The twinwall is like looking down the end of a cardboard box. It will have a clear sheet on the inside, a clear sheet on the outside, and a rib that runs through the center of the 2 sheets. In a cardboard box the rib is wavy. In a polycarbonate sheet the ribs runs straight between the 2 outer sheets. This is what will distort your view. You will see color, but not form like looking through a glass window. But fear not, there is an upgrade available to both of these greenhouses. We call these options the See Through Polycarbonate Greenhouse and the See Through Lean To Polycarbonate Greenhouse. These both come with the twinwall in the roof, for protection against hail and/or falling objects. The sidewalls have a clear view polycarbonate sheet that is exactly like looking out through a window. The best of both worlds.

Another great feature is that the ventilation package is included in the pricing of this greenhouse. It includes the thermostat, exhaust fan and intake shutter(s) in the freestanding models. The lean to greenhouses do not have the intake shutters. Your combination storm door will supply added ventilation and supply the air intake for the lean to models. This “free” feature definitely adds to the value of the greenhouse. These systems cost in excess of $500 typically. Also included in the upgraded model is a circulating fan. This is an often overlooked, much needed, option. These will aid in the health of your plants by keeping the air in your greenhouse moving and reducing the humidity in the plant canopy. They help to maintain an even temperature in the winter when the greenhouse is heated, helping to avoid hot or cool spots in corners. We offer the homeowner the choice of the optional roof vents. I personally prefer to have these, as I feel you get a lot of use out of them in the spring and fall seasons. They typically stay closed in winter and open in the summer, so the added benefit there would be natural ventilation in the summer months. The reason I like them in the “between” seasons is that you run the possibility of a cold night and a hot sunny day. You would want your vents open during the day and closed at night under these circumstances. That is why I always use automatic roof vent openers with my greenhouses.
The integral base is built into the greenhouse, so no need to build an additional base for the greenhouse. We do however recommend setting the greenhouse on a foundation of 4″ x 6″ timbers set down into the ground. We tie the timbers to the ground using rebar stakes. This will help keep your greenhouse secure in higher winds. Do you prefer to build a knee wall to place your greenhouse on? This is not a problem. We also offer an optional door drop to accommodate this. We just need to know the height of your kneewall in inches and we will adjust the frame while building it so that the door will fit to the ground.
This greenhouse is shipped by Common Carrier (truck line). It will come in 3 – 4 boxes depending on accessories and size of the greenhouse. Two people should be present to unload this greenhouse. These typically take about 4 weeks from the time they are ordered until the time you receive them. Your greenhouse is built specifically for you. There is no need to accept a “boxed” greenhouse with no options.
In closing, with all of the quality features, excellent pricing and the fact that this greenhouse is Made in the USA, we give it 2 (green) thumbs up.
Acadian and Evangeline Greenhouses
Acadian Lean To Greenhouse
I received an email yesterday with this in the subject line. STILL a very happy customer!!! Lynne and Mike were kind enough to share a few words about their tempered glass shed style attached greenhouse. They purchase their Acadian Lean To in 2007. It is always nice to hear that people are happy with their purchases. Following is the email.
Just wanted to reach out and express our complete satisfaction with your product. It has been ten years now and we enjoy the greenhouse as much now as when it was new. Many enjoyable snow storms and rainy afternoons. It has endured the severity of the east coast temperature extremes and provides sanctuary to our plants without fail. Can’t thank you enough for all of your customer service during the purchase and shipping process. I wish all establishments had your dedication to customer satisfaction. Thank you so much,
Mike and Lynn Gaither
Don’t be left out in the cold this year.
The same thing happens every year about this time. We are all still enjoying the warm weather of summer, getting the kids ready for school, and we forget about our beloved plants. I can’t tell you how many times in the past that Tom and I were installing greenhouses in the cold of the winter because they didn’t get ordered in time. Typically a greenhouse that is manufactured for you will take from 4 – 6 weeks for delivery. In the fall these lead times become extended, causing delays from the expected delivery times. This not only applies to greenhouses, it applies to polycarbonate sheets as well. They are typically delivered in 1 – 2 weeks, but in the fall they will take a week or sometimes longer past these times. So, even though it is really hard to think about it right now, if you are considering purchasing or building a greenhouse this fall, now is the time to start your decision process and get an order placed. Trust me, this I know from years of experience.
Advance Greenhouses Personal Greenhouse
Yep, That is Tom and my greenhouse. We really do practice what we preach. We think everyone in America should own a greenhouse! This was a rare snow storm in SE Louisiana. I don’t think the neighbors could even believe that we were outside in this mess. Today I just wanted to take a minute to reflect on the beginning and growth of Advance Greenhouses. Fifteen years ago Tom and I were studying how to get on the internet. We knew the product we were interested in, as we had been selling and installing greenhouses for a while. Our first adventure with polycarbonate was in 1993. We got a book about 4 inches thick on how to set up a website and dove into it. What in the world language were those people using? Something I had never heard of before. I am sure we fought and cussed our way through it and came up with what was an absolutely horrible website. But, people started to find us. We also did a lot of local garden shows to put the word out. Fifteen years later, here we are. Through the years we have had the pleasure of speaking and working with many like minded people. We love flowers, but we also love fresh food that we have grown for ourselves. Our greenhouse has been multi faceted. We have stored my cherished hibiscus plants, started seeds for the garden, started annuals and perennials for the flower gardens and even grown some food hydroponically in our greenhouse. As I tell people, it is a learning curve to figure out exactly what will work in your greenhouse. There are some hard, fast rules, but we are all growing different plants under different circumstances. We all have to do a little bit of experimenting to figure out what works exactly for us. In closing, we are running some sales this month as a customer appreciation (also an appreciation for what we have thanks to all of you). Visit our website to see the specials. Our business is very personal and very rewarding for both of us. Thank You! Tammy and Tom
