A cold frame is 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.

Using a Cold Frame
Cold frames can be sited on soil or on any level surface. They’re great for keeping salads going throughout winter, starting off tender crops, or hardening off indoor-sown plants.
When you click on the selection bar drop-down box in our Garden Planner and select ‘Structures,’ you can choose a cold frame to add to your plan. You can then drop the cold frame over your crops, and their growing season will be automatically adjusted to take into account the protected environment within the cold frame. You can also add other season extenders you may be using such as greenhouses and row covers to your plan.
