This is old news, circa 2010, however I recently came across it and so I decided to share it with you guys. I’m sure you all know about renowned architect Robert Adam of ADAM Architecture already. Well if you don’t, he has designed some incredible mansions/estates all over England. Back in 2010 he proposed to demolish the historic “Athlone House” in Hampstead and have this gargantuan mega mansion built in its place. The proposed copper-domed home was going to be built for a mystery Middle Eastern billionaire. It was reportedly going to cost at least £20 million to build and according to real estate experts, going to be worth £100 million if built. It was going to have approximately 50,000 square feet of living space with a ballroom, huge subterranean garage and numerous outbuildings.
