func_nobuild is a brush entity available in Team Fortress 2.

Entity Description

A func_nobuild entity will restrict an Engineer from building in the specific area it contains.

Normal Use

A func_nobuild area should come in contact with the top side of the brush you don't want the engineer to build upon. The func_nobuild should also be at least 96 units high to keep an Engineer from bypassing it by jumping above it. Keep in mind that a func_respawnroom entity also blocks an Engineer's ability to build, and thus a func_nobuild does not have to be placed in the same location as a func_respawnroom.

Note:Keep in mind that a func_nobuild only prevents the center of the Engineer's buildings from being placed on top of a surface, not the whole structure; parts of the building can actually overlap the func_nobuild area.

Todo: add picture example here

The required 96 units for each accessible side.

Ledges

High ledges present an element a bit different from a standard floor surface. If there is a ledge you do not want an engineer to build upon, the func_nobuild brush should not only be 96 units above the surface, but 96 units below the surface as well, with the func_nobuild brush overlapping the ledge. It should also stick out 96 units from all accessible sides of the ledge. If the ledge is less then 96 units above a larger flat surface, the func_nobuild only needs to touch the top of the surface the ledge is above.
