DIY Greenhouse plans - build your own DIY greenhouse, free step by step plans by ANA-WHITE.com

Preparation
- 3 - 2x4 @ 10 feet long - use on back wall
- 5 - 2x4 @ 12 feet long - use on sides/ridgepole DO NOT CUT
- 32 - 2x4 @ 8 feet long
- 11 - 12 foot x 26" standard corrugated plastic greenhouse panels
- 1 - 8 foot long x 26" wide standard corrugated plastic greenhouse panel (use on door side)
- 3 - 12 foot long tin panels (use on sides and back)
- 1 - 8 foot long tin panel (use on front)
- Tin screws
- 28 - 4' long ribbing strips
- L flashing (optional for the corners)
- You'll need either metal gussets for the trusses or to cut plywood ones from 1/2" plywood
Cut list is in plan at each step
Instructions
Step 1
Step 3
Step 6
- 4 – 2X4 @ 48” (BOTH ENDS CUT AT 22 ½ DEGREES, ENDS NOT PARALLEL)
- 1 – 2X4 @ 117 7/8” (BOTH ENDS CUT AT 22 1/2" DEGREES, ENDS NOT PARALLEL)
- 1 – 2X4 @ 55 3/8 (TOP CUT TO DOGEARED POINT, 22 ½ DEGREES)
- 2 – 2X4 @ 55 ¼” (TOP CUT TO DOGREARED POINT, BOTTOM CUT 45 DEGREES OFF SQUARE, END CLIPPED)
The back truss is built same as front. See next step for close up of the center cuts
Step 8
Step 9
- 10 2X4 @ 48” (BOTH ENDS CUT AT 22 ½ DEGREES ENDS NOT PARALLEL)
- 10 2X4 @ 47 1/4” (BOTH ENDS CUT AT 22 ½ DEGREES ENDS NOT PARALLEL) - shorter rafters go up to meet the ridgepole. I marked all shorter rafters to avoid confusion.
For the common rafters of this barn style greenhouse, we ended up using plywood gussets to save money. After cutting quite a few, I figured out how to cut gussets the super quick and easy way - got gusset cutting down to less than a minute each.
We put gussets on both sides of each rafter joint with glue and screws. We made all of the small trusses first on the ground, then it was just a matter of stacking them on the ridgepole and attaching to the studs. We used 8 screws per gusset. Common rafters are installed flush to top of ridgepole and flush to outside of side walls. We had to "toenail" the screws in - meaning they are screwed in at an angle. We used glue and 3" screws from both sides.
Step 10
The plan will get you through the framing.
At this point, you could use plastic paper, lexan glass panels, you name it to seal the frame in.
We used the corrugated plastic panels detailed earlier for installation. IMPORTANT: If you do not use panels you will need some sort of lateral support to keep the greenhouse from swaying side to side. Try 12 foot long 2x4s.
It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.

An amazing project
It really is an impressive project. I loved it from start to finish. I hope at some point to realize it.

Everyone's questions are not getting a response....
Hello. I am new here. I absolutely LOVE everything you build Anna!! Thank You so much for sharing your talent with us all.....
I am just wondering if you or someone on your team still reads these comments? From reading all of them start to finish, I now have several questions myself, that others have asked, that have not been answered.
#1 Is it 32 inch or 33"?
#2 The ballets (I think I named that correctly?) The piece you can buy or make yourself to connect the joints? More info. Please?
#3 In respect to the corrugated plastic panels being attached horizontally verses vertically? Snow load, leaking inside from rain, etc.?
#4 Last but not least, how to adjust the plans correctly for a 10 x 18 Greenhouse?
Any response will be GREATLY APPRECIATED!!
Thank You....

Is Step 9 missing a picture…
Is Step 9 missing a picture where you're explaining how you saved time to cut the gussets? I'm confused about that part.

Cut length
The plans depict 33” long 2x4’s for the walls, yet the cut list states they are 32”. Which is correct?
