Thanks Rick for the link. I've translated using Google and copied here for the convenience of English speakers.
Here's the translation by someone who speaks Dutch ;) :
How-To: Modular Buildings
We regularly see each other at meetings and bring along a construction or two of our own. An ideal standard for combining buildings is the so-called Café Corner Modular Standard (or CCMS).
But if you don't own a Cafe Corner, Green Grocer, etc., how do you know what rules to follow to make your building fit in with the rest?
I will describe the CCMS as applied in Lego's sets and as applied by many fans. There's basically two types of building in this standard. Will you write along?
1. Straight buildings
Generally speaking, every baseplate is 32 studs deep. The width is variable with straight buildings, always being a multiple of 8 studs. A common used width is 16 studs wide. The connection points, pavement, walls etc. will then have the following sizes:
Whether your building is 8 studs wide or 64 studs wide, the sizes in depth are always the same. That way the Technic bricks with hole will always align and allow for the buildings to be attached to one another through the use of Technic pins.
2. Corner buildings
In the case of a corner building, you're dealing with two connecting points at a 90 degree angle of each other. Therefore, your baseplate will always have to be 32 x 32 studs. Of course you can make the full building larger by attaching straight buildings forming a continuous whole at either side, but the corner module must be 32 x 32:
3. Variation in depth sizes
If you look at a real-life (old) street, you will see that not all buildings align in a perfectly straight line: some jut out a bit, others fall a little further back. If you put a number of CCMS buildings in a row, this method of alighnment will give you the best result. As long as you leave the Technic bricks in the right position for connecting, you're free to place your front and back wall at will. This might result in something like this:
Keep the variation in mind, because of your side wall. In some cases, part of your side wall will be visible. So if you were planning to omit your side wall, or make one out of all the colors you won't be needing for the front and back walls, make sure that at least the edge of the side wall that juts out is made of a color that fits with the rest of the building.
I myself always build an entire side wall if I know the building is going to end up in a combined layout with other builders: because you don't quite know what will end up next to you. For all you know you might end up next to a construction side, leaving your side wall entirely exposed.
The last point I wish to adress is height. In terms of height, you're basically free to do whatever you want. Make it as tall or as low as you wish. One floor 6 bricks high, eight floors 12 bricks high each, everything is possible. Do keep in mind though, that if you're making a very tall building, your side walls will definitely be visible. So make it into something exciting featuring windows or something, so it's not just one boring, flat wall. Do take care that you won't have anything protruding over the edges, since you may not know how high the building next to yours might be.
Variation in height is another reason to build side walls in a matching color when your creation will end up in a combined layout: the building next to yours might be very low and you won't know ahead of time.
Incidentally, Lego used to have a page explaining the modular standard, but it has sadly disappeared since then. It's still linked to at the Brickwiki page
for modular building, but all it does is bring up an error page
