My camp is thriving, and able to stave off most attackers so far. I simply have a walled-off ramp and a moat filled with carp on two sides, the other two are cliffs dropping several z-levels into sturgeon, lamprey, and carp infested water. Currently, only 4 fatalities, a merchant too foolish to avoid a lamprey-infested pool, a shooter I had that was rooting out fish, but ran out of ammo, and well... He got some slicer skill in before he died of lungs being ripped out.
The other fatalities were a melancholy mood and the trader who tried to clean up the shooter. Had two sieges from elves so far, neither was successful, and dug a channel with some bars set up in it to filter fish out so my kobs could drink safely. The fisherkobs stick to the waterfall for fishing, though they sometimes wander to the nearby pools. Currently working on housing for my kobolds, as I only have about 20 rooms.
Most complex building is a watch tower that stands 2.5 z levels high with fortifications on the top floor, and it has a basement level that was floored over after being channeled out, the purpose of the room is archery range. The first floor being weapons/armor/ammo storage, 2nd floor being 2 bedrooms for the shooters who guard the tower, and the roof is the ramparts. 7x7 building, 5x5 walking space inside.
Second most complex building is the drinking hall, a 6x16 structure with tables and chairs, stairs leading to the roof which is featureless. The only other "complex" building is burrows for housing under the wooden houses, which are dug from dirt rather than rock.
So far my only issue was when I went to play a kobold in adventure mode, there were no towns where I could get quests from kobolds, I had to wander to a dwarf capital which was the nearest town. Did kobold civilization die out?
Also, that adventurer was eaten by wolves >:
