I'm not sure I quite understand the question.
Why isn't the CCC just to LEGO Standard's ? The MOC's would be like *new* sets. And it would fit with my stuff
The CCC standard was designed to be a happy medium
rigid enough to please those who like a little structure
in the layout, and free enough to allow some creativity
and innovation in the layout. Also, bear in mind that the
standard is primarily for group displays.
Lego Castle standard, is 2 bricks wide on the wall, and
3 bricks wide on the top (to allow the guard to "stand"
on it). There is also a plate near the top to allow the
added stud to be added near the top.
The CCC standard is to be double the width, or double
the lego standard...so that the walls are 4 studs thick,
and on the top, 6 studs, with the plate near the top
to allow the guards to stand there.
There is to be variation of course, especially on the corners.
But essentially that is standard.
On the buildings themselves, use regular plates, rather
than baseplates to allow better intigration into the
city, and to allow easier layout of the roads/paths to
be decided by the layout coordinator.
I hope that clarifies the standard itself.
