architecture library (walls, doors, etc)

Hey guys,

I am looking for a libreCAd library.
I need some walls, windows, doors and stuff like that.

Maybe there is a nice tutorial how to design a room!?

Does anybody know something like this?

There is a library containing furniture, sanitary objects and other accessories ( http://wiki.librecad.org/images/d/d9/Architect3-LCAD.zip), but not for walls, doors etc.
Also there is a tutorial http://forum.librecad.org/file/n5708464/tutorial_-_let's_draw_a_little_house_project.zip
It is a bit outdated, newer LC versions have a feature for architectural dimensioning ( fixed extension line length). Also it uses no units, that's more for experienced users and causes confusion when setting scale for printing, I recommend using units (mm, cm, m, inches, feet).
