Designer Antti Lovag long rebelled against traditional structures, and the Bubble Castle is a perfect example of his radical approach to rethinking the built environment. The bulbous compound sits on the southwestern coast of France. There are no sharp angles or straight lines in this unusual design. Lovag unified the home with its natural surrounding by bringing outdoor elements inside, including palm trees and a waterfall. “This home is incorporating these outdoor rock croppings in a way that links them to the overall bubble concept,” architect Peter Koliopoulos says. The house has already been deemed a historic monument by France’s Ministry of Culture, despite the fact that it’s not even 50 years old.
