With that kind of eye for detail you're buildings are bound to rock!
also nice find on the bitzarium, didn't knew that site existed
perhaps it's not a bad idea to compile all existing bits sites in one thread?
I don't have time to look em all up now but here's from the back of my head:
Hoard 'o bits
Garage a bitz (france)
the bitz barn
bits and kits
please feel free to complete this list if you know anymore
