Install the window on one end in the opening with hinges and the storm door on the other end.

To make beds I used 1 x 10 locust boards. I made two 4 ft. wide beds along each side with a 2 ft. path down the middle. It is not a good idea to use pressure treated wood since it’s treated with chemicals that may leach into the dirt.

Plant the beds with good things to eat and enjoy having a longer growing season in your own yard!
