10×12 Greenhouse Door and Trims Plans

This step by step diy project is about 10×12 greenhouse trims plans. This is PART 2 of the greenhouse project, where I show you how to build the vents and the door for the greenhouse. In addition, I show you how to fit the 1×2 trims to the exterior of the greenhouse. 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 vents, door and trims

Fitting the ridge beam

Use 2×4 lumber for the supports and 2×6 lumber for the ridge beam. Drill pocket holes at both ends of the supports and then secure them into place with 2 1/2″ screws. Make sure the corners are square and then plumb the supports with a spirit level.

Building-the-rafters

Build the rafters from 2×4 lumber, using the pattern shown in the diagram. Use a circular saw to make cuts to the rafters and then smooth the edges with sandpaper.

Fitting the rafters

Fit the rafters to the top of the greenhouse. Place the rafters every 24″ on center for a professional result. Drill pilot holes and insert 2 1/2″ screws to lock the rafters into place tightly.

Side wall trims

The first step of the project is to attach 1×2 trims to the side walls of the greenhouse, after covering the structure with greenhouse plastic. Align the edges flush and secure the trims into place with 1 5/8″ screws, every 8″ along the framing.

Back wall trims

Fit the trims to the back wall of the 10×12 greenhouse, as well. Align the edges flush and then insert 1 5/8″ screws every 8″, so you can lock the trims into place tightly. Make sure the corners are square and leave no gaps between the trims.

Front wall trims

Fit the 1×2 trims to the front wall of the greenhouse, as well. Align the edges flush and insert 1 5/8″ screws, every 8″ along the framing.

Fitting the roof trims

Fit the 1×2 trims to the top of the greenhouse, as well. Align the edges flush before inserting the screws.

Building the vent frame

Use 2×2 lumber for the vents frame. Drill pilot holes and insert 2 1/2″ screws to lock the frame of the vents together tightly.

Vent trims

Fit the 1×2 trims to the vents, as well. Use 1 5/8″ screws to lock the trims to the trims into place.

Fitting the vents

Fit the vents to the sides of the greenhouse and install the hinges, so you can open and close them easily. In addition, you can install automatic vent openers, so you air the greenhouse when the temperature get over a certain level.

Greenhouse-door-frame

Assemble the frame of the doors from 2×2 lumber, as well. Cut the components at the right dimensions and then lock them together tightly with 2 1/2″ screws, after drilling pilot holes. Make sure the corners are square and align the edges flush.

Door trims

Fit the plastic and the 1×2 trims to the doors.

Fitting the front door

Fit the doors to the openings and then lock them into place tightly with hinges. Check if the doors open and close properly and make adjustments, if necessarily.
