There would be a hell of a empty unusable spaces in that house. But still a nice idea I guess. 

 You can always put some plants, make a jungle house

 I'm just waiting for IKEA to release a line of curved furnitures to furnish this kind of house. 

 There's a country that set up bubble houses as social housing and it sucked apparently.

But they were like spheres not curvy walls like this. I think this wouldn't be so bad.

 Looking at the interiors, small. Lots of light on the living room though. 

 Why? The internal construction would be abysmal to set up... How will you handle insulation or HVAC? It is cool in theory, but the long-term ramifications would be very costly.
