If I had the luxury of time and money that's the kind of home I'd build out, probably with a few Maginot line type turrets peeking out from the "roof".

For light, I'd have one or more glass or glass block domes on top.

I kind of like the idea of the conjoined egg-shaped rooms, but not the practicality of cylindrically- or compound-rounded walls.
