I've said it before, I'll mention it again.
I absolutely must make the dimensions of every room an odd number, even halls must be 1, 3, 0r 5 wide, and measured in odd-numbered lengths in ways that i can make odd-number dimensioned rooms out of them. the smallest rooms are usually 1x2 so that i can make them in sets of 2x5 stuffed neatly into a 5x5 block between 4 halls that are 3x5 with corners that are 3x3, with a 1x doorway joining them. the middle-class rooms are almost always either 3x5 or 5x5, and upperclass/nobles rooms are made from 11x11 blocks cut so there's a 7x7 dining room, a 3x7 bedroom, and a 3x11 engraving hall, seperated by 1x walls with a door leading to each of the other rooms.
Workshops are grouped in fours in a 7x7 room, except the farming related shops, the still, kitchen, fishery, butchery, and farmers' workshop, which I arrange in a 7x11 room in such a way as to leave as much floor space in the middle as possible. Stockpiles are always 23x23 or similar, usually stacked vertically.
All my dwarves must have labors turned on to make up specific classes, but there's even more detail here and I don't want to be charged with negligent homicide because your head explodes trying to understand how stupid I am. You can't.
