OK, you struck it rich and have boat-loads of money to spend on your house...  Why not have a huge exterior wall made entirely of glass?!! 

Worried about privacy?

You dont have worry if you buy the glass from a company called Saint-Gobain. 

They make a kind of high-tech glass that can change from transparent to 'frosted' - by turning on a switch! 

The intelligent privacy glass is called Privalite.
