a few concepts to get before starting:
a linedef is a line that can create up to two sectors, one on each side. one of the sides is considered the "front", which is the side the buttons and doors are triggerable. the linedef's sides can be flipped.

0 |- 1 => *flip* => 1 -| 0
| |
sector is not a room, but it should be if you want to avoid problems similar to halls of mirrors or misbehaving doors. it is represented as a number. any good sector is defined by linedefs enclosed, "pointing inwards" or referencing the same sector.

rooms are connected by linedefs that references two different sectors, one for each side. the setup above allows you to make floors and ceiling with different heights, and a fake wall if you want like the one found in e1m1's secret, at the zig-zag area,
or even a button. you can make part of this linedef impassable if you want.

the above setup only allows you to place a fake wall, a button and make part of it impassable.
the info above should help you addressing unclosed sectors and understanding mapping exploits, or creating interesting effects.
