Global warming has struck Paris first! Buildings have started melting! OK, I'm kidding (and believe me it's not hot in Paris at all at the moment)! All of these windows and balconies are totally fake. They are painted on a huge cover that hides work at the Bleecker Group building on Avenue Georges V. It's really fantastic. Athem is the company that made this masterpiece. Congratulations and a big thank you to - sometimes not nasty - GG who gave me this info.
