Well I've sort of finished the second building now, it just needs a little touching up where black paint has got on to the white. Plus whilst painting it I've learnt a few things: yes foamboard warps (as mentioned earlier); it's a good idea to paint the insides of buildings with stairs and internal supports before putting them together otherwise you end up with the afore mentioned black paint on your nice white walls as you hand is doing contortionist impressions!
But without further ado the next building:
