This futuristic-looking home may, in fact, be the coolest living space in the world. Designed in the 70s and built in France, this home has deep roots in the arts with fashion designer Pierre Cardin owning the place and Hungarian architect Antti Lovag designing it. It’s so impressive that the french ministry of culture has listed the “bubble house” as a historic monument. The interior is spacious and oval in shape throughout, providing plenty of natural light and entrances to various rooms, one even leading directly over the outside pool so you can take a dive if you so choose. The windows are aplenty and were strategically placed and shaped to accent the beautiful volcanic Cote d’Azur landscape.
