This step by step diy project is about 10×16 greenhouse plans. This is PART 2 of the wooden greenhouse project, where I show you how to build the roof and how to fit the doors and the vents. You can make adjustments to my plans and fit more vents or change their locations (for ex. fit the vents between the rafters). 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.

How to build a 10×16 greenhouse roof
Build the rafters for the greenhouse from 2×4 lumber. Use a miter saw to make the angle cuts, as shown in the diagram. In addition, mark the cut lines to the opposite end and use a circular saw to make the cuts. Notice the base notches are different for the end rafters.
Fit the rafters to the top of the greenhouse, every 24″ on center. Drill pilot holes and insert 3 1/2″ screws to lock the rafters into place tightly. Use 2 screws for each joint and drill the pilot holes at angle.
Use 2×4 lumber for the gable end supports. Drill pocket holes at both ends of the supports and secure them into place tightly with 2 1/2″ screws. We need these supports for the polycarbonate sheets.
Next, we need to attach the siding sheets. Cut the T1-11 siding sheets to 24″ and then secure them to the studs, every 8″, using 6d nails.
Continue attaching the siding sheets to the sides and front of the greenhouse.
Attach the 6mm polycarbonate sheets to the sides of the greenhouse and secure them to the studs with the corresponding screws (designed for these sheets). Fit H profiles between the sheets, to seal the gaps.
Fit the sheets to the back of the greenhouse. Cut the sheets and secure them to the frame using polycarbonate screws..
Repeat the process for the front of the greenhouse. Notice the cuts around the door opening.
As you can see in the diagram, you need to fit H profiles on the lateral joints. In addition, fit U profiles for the end exposed edges. These profiles protect the twin layer polycarbonate sheets from dust, water etc.
Fit the sheets to the top of the greenhouse, with the appropriate profiles. In addition, you need to fit a profile for the ridge cap.
Use 2×4 lumber for the door frame. Drill pocket holes at both ends of the vertical and middle supports, as shown in the diagram. Align the edges flush and make sure the corners are square. Leave no gaps between the components and insert 2 1/2″ screws.
Cover the door with a panel and then lock it into place with screws.
Fit the door to the front and back wall openings and lock them to the frame with hinges. Attach latches to keep the door locked.
Use 2×2 lumber for the vents. Drill pocket holes at both ends of the vertical components. Align the edges flush and make sure the corners are square. Insert 2 1/2″ screws to lock the frames together tightly.
Attach the panel and then insert the screws.
Attach the vents to the openings and then lock them to the framing with hinges. Install an automatic vent opener so you can control the climate inside the greenhouse.
Check out PART 1 of the greenhouse project, where I show you how to build the frame for the greenhouse.
This is a sturdy greenhouse that offers an ideal mix of space and it is also cost friendly. You can adjust the slope of the greenhouse if you live in an area with heavy precipitations.
