This is a guest post from Antonina of OpenBuildings - a community-driven and openly editable encyclopaedia of buildings from around the world. 

It happens so everybody needs to visit them once in a while. For many of us in Europe and the US there is nothing public about the programme they accommodate so these inescapably important amenities have become a sort of a grey zone in public buildings (yep, that’s what they are). People around the globe – and in history – have developed their unique perception, level of open-mindedness, fair share of humour and own terminology for public lavatories. Whether it’s the ‘restroom’, the ‘loo’, the ‘house number 00′ you need to visit or you just happen to ‘powder you nose’ once in a while, it is a fact worth noting that these small public amenities are a challenging opportunity for inspiring design .
