This step by step diy project is about diy 10×12 greenhouse shed plans. If you are serious about gardening and you want to protect your plants from harsh weather, this greenhouse with shed storage is a fantastic project. Moreover, I have designed shed with many sizes so check them out, as well. 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. See all my Premium Plans HERE.

How to build a greenhouse shed
The first step of the project is to build the floor frame for the greenhouse shed. Cut the joists at the right dimensions from 2×6 lumber. Align the edges with attention and check if the corners are square. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components.
Use 4×4 lumber for the skids. Place the skids on a level surface and place them equally spaced. Fit the floor frame to the skids and lock them together with rafter ties. Align the edges flush for a professional result.
Use 3/4″ plywood for the floor frame. Cut the sheets at the right dimensions and then attach them to the joists. Leave no gaps between the sheets and secure them into place tightly with 1 5/8″ screws, every 8″ along the joists.
Continue the project by assembling the wall frames for the front and back of the greenhouse shed. Cut the plates and the studs as shown in the diagram. Lay the components on a level surface, drill pilot holes through the plates and insert 3 1/2″ screws into the studs.
Next, you have to frame the front wall with the door opening. Cut the components at the right dimensions, drill pilot holes through the plates and insert 3 1/2″ screws into the studs. As you can easily notice in the plans, you need to install a double header for the door opening.
Frame the other back wall frame using 2×4 lumber, 3 1/2″ screws and the same techniques described above.
Build the tall side wall from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center for a professional result. Fit 1/2″ plywood between the double studs placed at both ends of the wall frame.
Frame the opposite side wall for the shed. As you can see you also need to frame the vents for the greenhouse shed. Drill pocket holes at both ends of the supports and insert 2 1/2″ screws into the studs.
Fit the wall frames to the floor of the shed. Align the edges flush and use a spirit level to plumb the walls vertically. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor frame. Moreover, you need to lock the adjacent walls together tightly. Drill pilot holes and insert 2 1/2″ screws.
Fit the T1-11 siding sheets to the side wall of the greenhouse shed. Align the edges flush and insert 6-8d nails, every 8″ along the framing, so you lock them into place tightly. Leave no gaps between the sheets for a professional result.
Cut the siding sheets for the small side wall. Fit the siding sheets to the walls and lock them into place tightly with 6-8d nails. Insert the nails every 8″ along the framing. Make sure you cut out the vent openings.
You need to check out PART 2 and PART 3 of the project where I show you how to build the roof and the door for the greenhouse shed.
This is one of a kind outdoor project, where I show you how to build a greenhouse shed. If you like flowers and other plants, this shed will protect them from the bad weather. There will be plenty of light inside the shed. You can build benches so you can use the space at maximum.
