This step by step diy project is about 10×12 greenhouse plans. I have designed this medium sized greenhouse so you can grow fresh vegetables in your own backyard. This is a sturdy greenhouse with a roof pitch of 6:12. The greenhouse has a door to the front and 2 vents on each side. The vents can be automated with openers, and you can add more vents if you live in a warm climate. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

It’s that easy to build a greenhouse!
How to build a 10×12 greenhouse
The first step of the project is to build the base for the greenhouse. Therefore, you should use 4×4 pressure treated beams, because they are resistant to moisture. Use a circular saw to make the notches to both ends of the beams. Make parallel cuts inside the areas and then use a chisel to remove the excess. Smooth the recess with a chisel.
Selecting the location for the greenhouse is essential for the project, as most plans need plenty of direct sun light. Therefore, choose a location that is exposed to the south and then level the surface thoroughly. Lay the beams and align the corners. Drill pilot holes and insert 3 1/2″ screws to lock everything together tightly. Make sure the corner are square. Use a L-square and check if the diagonals are equal.
Fit the 2×3 anchors along the side skids and then insert them to the ground till they are flush with the beams. Use 2 1/2″ screws to secure the stakes to the base of the greenhouse. This is a very simple method to anchor the greenhouse to the ground, but make sure you adjust the depth of the skids according to the winds in your particular location.
Use 2×4 lumber to frame the side walls. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center and align the edges with attention. Make sure the corners are square.
Fit the 2×4 supports to create the openings for the vents. Drill pocket holes at both ends of the supports and insert 2 1/2″ screws to lock them to the studs.
Build the front wall for the 10×12 greenhouse. Assemble the double header using 2x4s and 1/2″ plywood. Add glue to the joints and insert 3 1/2″ screws from both sides.
Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Frame the door openings for an easy access to the interior. You can adjust the size of the size of the openings to suit your needs.
Build the back wall in the same manner described above. Make sure the corners are square and place the studs every 24″ on center.
Lift the wall frames to the base of the greenhouse and plumb them with a spirit level. Drill pilot holes through the base plates and insert 3 1/2″ screws into the base. Drill pilot and insert 3 1/2″ screws to lock the adjacent walls together tightly. Make sure the corners are square and align the edges flush.
Drill pocket holes at both ends of the vertical supports. Fit the 2×4 supports to the middle of the top plates. Plumb the supports and lock them into place with 2 1/2″ screws. Fit the 2×8 ridge beam to the top of the supports and make sure the corners are square.
Use 2×4 lumber for the diagonal braces that will support the ridge beam. Make 45 degree cuts to both ends of the braces and drill pocket holes, as shown in the diagram. Insert 2 1/2″ screws to lock the braces into place.
Check out PART 2 of the greenhouse project, where I show you how to build the door and the roof for the greenhouse.
This is a wooden greenhouse built with 2x4s studs placed at every 24″ on center. The greenhouse is covered with plastic film. You can build this greenhouse in less than one week and you can then start growing vegetables. You can adjust the size of the greenhouse to suit your needs.
