A “kosher” Sukkah needs at least two complete walls and a small part of a third wall. The walls can be of any material, as long as they are sturdy enough to withstand a normal wind. The walls should be at least 38 inches high (96 cm), but not higher than 30 feet (9.6 m).

1 Answer. A Succah without a flat roof at all e.g the entire walls slant and meet in the middle like a tent, alternatively one wall is slanted against a straight wall is Invalid.

One must first erect the walls and only then place the sechach covering. If the sechach is put up before there are walls in place, the sechach should be lifted up and reapplied. It is best that a sukkah have four solid walls (aside from the doorways and windows).

The typical explanation for the sukkah is that it symbolizes the booths in which the Israelites dwelled during their journey through the desert. On Passover we eat matzah because our ancestors ate matzah when they left Egypt, and on Sukkot we reside in booths to commemorate those in which they lived for forty years.
