Introduction: Our First Greenhouse

So I started a garden 4 years ago and my husband thought I wouldn't stick with it longer than the summer, but he was wrong!! :) I've added on more and more each year, starting everything indoors from seeds and transplanting them outside when its time. This year plants were taking over my home office so I decided that I needed a greenhouse! It took us less than a week to build and the cost for everything was a little under $700. We didn't use top notch materials for this greenhouse but it stays dry inside and will definitely last me a few years. Since this is my first greenhouse it will be a learning experience for sure but I can take notes for improvements for my next one!

Supplies

  • Tuftex Poly Carb Plastic Roof Panels
  • Tuftex Screws
  • 5 - 2x4's
  • 26 - 2 x 3 x 8 boards
  • 4 - small cement blocks
  • OSB board
  • Tuftex Wood Solid Roof Panel Closure Strips
  • Pine Fence boards ( or whatever material you'd like for the outside boards)
  • Pea Gravel
  • Stepping stone pavers of your choice

Tools we used:

Miter Saw

Drill

Level

Step 1: Level the Foundation

The least fun part of this whole process is leveling the ground!!! After you have done that you are ready to put down the base. Using the 2 x 4 x 8's, cut 2 at 82" and 2 at 89". Fasten together with screws. We used 4 small cement blocks under each corner for more support and to keep it slightly off the ground to help with rotting. Use a level to make sure all sides are even.

Step 2: Building the Side Walls

For the side walls, we used 5 2 x 3's ,cutting them in half to 48" for the studs and 4 2 x 3's (2 on each side) for the top and bottom wall. Space the boards 24 inches apart to make the spacing nice and even across and fasten together with screws.

Step 3: Front and Back Walls & Roof

For the front and back walls we used 2 x 3's using these measurements:

(2) 46 1/2 " for the outer sides - Same for back wall

(2) 24 1/2" for the bottom- back wall use 1 board at 77"

(2) 71 7/16" for the door frame- Same for back wall but cut 1 board at 23 3/4 " to make window

(2) 23" for the top sides-Back wall cut 2 25 1/8"

(1) 31" for the top of the door frame, sides cut at a 45° angle- Same for back wall

For the ridge beam we used a 2 x 4 board and for the end rafters 2 2 x 3's cut at 56 15/16". Cut one end at a 45° angle and cut the birdmouth at the other end.

Cut 6 additional 2 x 3's 56 15/16" cut the ends just like the end rafters and align and secure them with the side wall studs.

Now for the panels!!! We put a Tuftex Wood Solid Roof Panel Closure Strips on each 2 x 3 on the roof and attached the Poly Carb panels with the screws. We continued that on the front, back and sides until everything was sealed up!

Step 4: Walls and Door

We used OSB for the lower walls and 2 x 3's to make the outline of the door. We had some Poly Carb roof panel left over so we used that to fill in the door.

Step 5: Curb Appeal

We used pine fence boards to give it a nice curb appeal! Put a few pavers down so I would have something solid to stand on and filled the rest in with pea gravel. We made some benches for each side for my plants and we have ourselves a greenhouse!!

Step 6: Finishing Touches

The final step was to figure out ventilation. We probably should have done that first but after a lot of thought and trial and error we figured something out! There wouldn't be enough air flow with the window in the back since its up against the house so we decided to have the sides open. I bought steel folding shelf brackets from amazon and used 2 per side. They go up and down smoothly. We were afraid of the wind getting underneath them so we put some latches on each side to secure it from wind.

It was a lot of fun building this and I couldn't have done it without my wonderful husband!

    Question 10 months ago on Introduction

    It has been my goal for the last couple years to build my own greenhouse and start harvesting my own seeds and starting out from the beginning with this. It has felt a little daunting trying to plan it at times and I came across the picture of your little green house and you make it sound so simple, and it's absolutely perfect. The only concern I have is the cost for materials. Do you remember about how much it cost to build the greenhouse. Again, it is absolutely perfect and almost exactly what I had pictured my mind.

    It cost us about $600 for all the material. You could use plastic sheeting for the roof instead of the panels, that would cut down on cost but I don't know how well it holds up. This one has held up extremely well with heavy rains and wind. I hope you get to build your greenhouse! I'm in mine just about everyday, even when its raining I can still work in it. Good Luck to you!

    I really love how simple the design is! I think I may be able to modify this to make a greenhouse strong enough to hold up to the weather where I am. :D

    Question 1 year ago on Step 1

    What is your experience with severe weather with this build (snow, hail, wind)? We are in upstate NY, and get some pretty heavy snow, and below zero F. often during the winter.

    We have had a good bit of hail and wind this year and nothing has been damaged so far. The wind has been extremely bad at times and the greenhouse is still in perfect condition. I haven't had it through a winter yet. Some years we get a little snow and other years we get a lot but I'm confident that it will be fine. :)

    Great Greehouse build looks to be the right size height wise, love those benches inside and what a great idea using shelf brackets for the window ventilation.
    Well done.

    Hey what is that called? I haven't been able to search it with any luck :( Maybe a link to get me started :) Polycarbonate yellows in the sunlight, has that been an issue? Are there other materials, maybe something a little more translucent? Thanks

    You can't find the Polycarbonate panels? We got them at lowes but when we started researching everything in the beginning, it looked like it was going to be hard to find greenhouse panels of any kind that were in stock. These happened to be in stock at the time in our area. https://www.lowes.com/pd/Tuftex-PolyCarb-2-17-ft-x-8-ft-Corrugated-Polycarbonate-Plastic-Roof-Panel/3043439

    They haven't yellowed at all and the sun beats down on it a majority of the day. I'm looking into making some shade panels now. I'm sure there are other materials out there. I liked the look of these and with the price and being in stock at our Lowes, that is what we went with. :) Hope this helps!

    I was most impressed with the curb appeal! What a great job you did.

    Thank you! I love to decorate and design so I felt like my greenhouse needed my own touch of curb appeal!

    Love the project! Turned out really well.
    Was really impressed at the dedication on the wavy profiles.
    I did a similar thing for a greenhouse/cold frame (and also a 3D Printer Enclosure as it happens) with this 4mm Polycarbonate Sheet. Also check it out for smaller builds, as it's also great for greenhouses and cheap.
    (It's also safe around kids).
