Cold frames are easy to make at home using salvaged windows, wood, strong hinges, some wood screws, and handles if you wish. The only tools required are a drill and a screwdriver.

How to Build a Cold Frame

First source your lid (or lids). An old window or even a shower door will work well. Then cut lengths of lumber to size to match your lid. You can choose how tall you’d like your cold frame to be, but make sure it’s one board higher at the back than at the front to enable the frame to soak up maximum sunlight.

Cut one of the side boards diagonally along its length to give you two triangular boards, one for each side, to match the slope from back to front.

Screw all of the boards to four corner posts that match the height of the front and back boards. You’ll also need two battens to use as props for venting the cold frame on sunny days.
