If you want to learn more about building a 12”x12” greenhouse that is ideal for several pots or for planting seeds, pay attention to this article. Make sure you cover the structure with vinyl sheets in order to protect the plants from harsh weather. Glue or staple the sheets to the frame.
Work with good judgement and don’t forget to take a look over the rest of the related plans, as there are many designs and woodworking projects to select from. Work with attention and don’t forget that a good planning will save you from many issues and it will keep the costs withing the total budget.

How to build a greenhouse
First of all, you need to build the two frames of the wooden box. Use 1×1 lumber for the components and cut them at the right size. Drill pocket holes at both ends of the short components and insert 1 1/4″ screws into the perpendicular slats.
Next, you need to assemble the wooden box by fitting the vertical supports to the structure. Cut the supports at the right size and drill pocket holes at both ends. Fit the supports to the frames, make sure the edges are aligned and secure them into place using 1 1/4″ screws. Make sure the corners are right-angled before inserting the screws.
Continue the project by building the lid. Start by assembling the base of the lid. Cut the components out of 2×2 lumber and drill pocket holes at both ends of the short parts. Use 1 1/4″ screws to lock everything together tightly.
Build the rafters out of 1×1 lumber, making sure you cut both ends at 45 degrees. Fit the rafters to the frame and lock them into place using 1 1/4″ screws. Build the top ridge out of 1×1 lumber. Drill pocket holes at both ends of the components and secure it to the rafters using 1 1/4″ screws.
Fit the lid to the greenhouse box and lock it into place with hinges. In this manner, you will be able to open and close the lid easily.
One of the last steps of the woodworking project is to take care of the finishing touches. Therefore, fill the pilot holes with wood putty and smooth the surface with 120-grit sandpaper.
Top Tip: If you want to enhance the look of the project and to protect the mini-greenhouse from decay, we recommend you to cover the components with paint or stain.
