The walls of a sukkah can be made of any material, provided that they are sturdy enough that they do not move in a normal wind. You can use wood or fiberglass panels, waterproof fabrics attached to a metal frame, etc. You can also use pre-existing walls, such as the exterior walls of your home, patio or garage as one or more of the sukkah walls. An existing structure that is roofless or has a removable roof can also be made into a sukkah by covering it with the proper schach.
The Roof Covering:
The sukkah needs to be covered with schach which must be something that grew from the ground but is currently disconnected from it. Common sukkah roof-coverings are: bamboo poles, schach mats made from bamboo or reeds, evergreen branches, corn stalks, or narrow strips of unfinished lumber.
The schach must be detached from its source of growth—thus a live trellis, or branches still attached to a tree, cannot be used. You may also need some plain, unfinished wood beams to construct a framework on which to lay the schach.
If you’d like to set up a lighting system, and your sukkah is built close to an outlet, purchase a light bulb with a rain protection cover and electrical cord.
Chairs and Tables:
Remember, you will be eating all of your meals in the sukkah for the duration of the festival. It is also a special mitzvah to invite guests to share meals with in your sukkah.
Many communities decorate the sukkah with colorful posters depicting holiday themes, by hanging fresh fruits or other decorations from the schach or wooden support beams.
