We helped Josh’s wife make a DIY Greenhouse with help from Lowe’s. It was a fun & challenging build, but Lowe’s is the perfect partner to help you finish your fall projects and
get back to enjoying what matters. Look below for everything we used in this project!

Josh’s wife is really into gardening and planting beautiful greenery leading to her desire for a greenhouse. This way, she can keep her plants alive during the winter months and incubate some new plants so they’re ready for the spring.

Josh began the design with a 3d model in Fusion 360. We got our bill of materials and the cut list then headed to our local Lowe’s to get the supplies to begin framing the structure. I chose to use pressure treated lumber for this exterior addition to resist the moisture and humidity that may build up inside the greenhouse. Using Josh’s measurements, we nailed together the floor and added the front and back wall studs.

Before adding a structure to your yard, you may chose to grate and level the area beforehand. Josh didn’t want to tear up the yard, and here in Kentucky, the clay is super hard. In lieu of digging into the ground to level it, we chose to level the floor frame by adding 2×4 posts semi-driven into the ground. This way, Josh and i could level the floor and nail it to those posts along the span of the greenhouse. Now that we had a level surface to work from, we continued to build out the frame by connecting the front and back studs and then connecting those two walls with some ceiling joists.

For the greenhouse floor, Josh wanted something that could resist any standing water that would fall down from the plants. We found some engineered siding panels at Lowe’s that are weather-resistant and come in large, 4′ x 8′ sheets. These panels are only 3/8″ thick, so we added another layer of pressure treated 1/2″ plywood to ensure the floor was strong enough to walk on. We fit three of these double-layered panels on top of the floor frame, making sure to cut around the wall studs and secured them with screws.

For the greenhouse’s exterior, it is possible to simply cover the bare frame with the clear polycarbonate sheets, but because of this greenhouse’s size, that would take more than the 10 panels we allotted for this project. We had to order the sheets from Lowes.com and the came in a pack of 10. So rather than sacrificing the size of the greenhouse, Josh got creative and added a decorative element to the outside that helped use less polycarbonate.

We decided to use the cutoffs of the engineered, exterior sheeting to make a skirting of wood panels that wrapped around the greenhouse. To cover any seams and to give the element some definition, Josh cut up some 1×4 trim pieces that really set the decorative element apart. It looked really nice and flowed super well with the overall design. Again, these step is optional, but it does look fantastic and it helps save on the more expensive material later.

At this point in the project, we have a nice looking frame of a greenhouse. To make it functional as a greenhouse, we need a way to trap the radiant heat from the sun inside the structure. We found many ways to do this from using reclaimed windows, rolls of plastic tarp pulled tight, glass panes, and sheets of acrylic.

  1. Answer to common comments:
    1. The 2×4 legs won't settle much here. Our red clay doesn't move much once it's settled, and this is a high point of the yard so it drains well and never gets saturated.
    2. All wood was pressure treated, rated for ground contact, so rot is many, many years away.
    3. There is a small air gap between the walls and the side of the house.
    4. The garage (not temperature controlled) is on the other side of that exterior wall.

  2. Why not remove the grass undeneath the boards since they'll just die and cause fungal growths?

  3. Just a thought… this was built against a vinyl siding wall. I would venture to say that if this on the south side of the house, the siding has warped and melted due to the intense heat generated via mister sunshine. I once saw a section of vinyl wall melted due to the reflection from the nieghbors windows. Just sayin. Still, all in all, not a bad greenhouse ; )

  4. Absolutely fcking terrible design. It's embarrassing…. those 2x4s are going to sink into the ground and it's not going to be level… you just put down landscaping fabric and gravel then use blocks or cement footers and attach it to the house.

  5. Show us the state those roof vents are in after one year of use and weather abuse. I'm not at all convinced that rickety setup with a bit of tape lasts.

  6. Wow! I like that double sided plastic panel material. I'll have to check the price on that when I do another greenhouse. I basically used special huge roll of greenhouse plastic ordered from a farm supplier, but what you ordered looks really good. That flex tape is also something I want to look into for repairing small holes.

  7. If only it were that easy to get straight 2×4's from Lowes….I see the sh*ttiest most warped lumber there LOL.

  8. I'd like to see how leveled that green house is now with probably those "leveling" legs out of 2×4 are rotten now and probably sunk into ground after first rain, and those plastic panels probably destroyed by sun by now.

  9. Does this type of clear plastic sheeting filter out any of the Sun’s full spectrum rays in the way that Low E Glass does?

  10. At about the 9:30 mark, the guys are installing a strip of plastic about 3 inches wide vertically between the panels. Is this necessary? And does it go under the panels or over?

  11. Please please, change the loud horrible noisy music you use. Its not necessary. I would rather hear nothing—by the end of your videos I have a headache.

  12. The one thing I always find humorous about DIY builds on YouTube is how quick, accurate and effortless they suggest the build can be for all of us, despite the fact they're usually using top of the line (or at least decent) powertools to do it. And they're usually freebies!

  13. Love it! Simple, nice lines and very attractive. This is what I was looking for! Only I will be using pallets. I like the clean look, more minimalistic type and you guys pinned it. Awesome greenhouse! Thank you for sharing this build! Looks like I will be busy the next few days or so.

  14. Make sure you cut the roof flush. I used these panels to build a greenhouse for Mom (which she refused to use) and last night I needed to go to the E.R. because a corner gouged my eye.

  15. Rubbish video, unless one is RICH.
    MOST PEOPLE might Have a house but most people DO NOT HAVE ALL THE EQUIPEMENT / TOOLS shown.
    ALSO, FOR MOST OF THIS VIDEO, YOU FOLKS HARDLY EVER USED YOUR WORDS.
    FAIL !

  16. Nice but the floor is wrong. Use gravel floor. You'll get over ran with bugs and not one's you want around garden's

  17. These would be better without the distracting sound bytes folks are calling music 😖

  18. hey josh how much wind did it take before you lost first panel. how bout dem roof vent hinges? lol
