Subterranean Home: Sick, Alien

You know what would be a good idea: double basements.  That is, you have a basement that's twice as deep, so you have two floors underground.  I know it sounds crazy, but think of the benefits: you have more room in your house without compromising the space in your yard.  You have free insulation.  The ground moderates the temperature of the interior.  But best of all, it is the embodiment of the suburban dream: you live near your neighbours, yet you can also get far, far away from them.

I know, you don't like the idea of living below ground without windows.  Well, you don't really need windows: it's not like the view really changes in suburbia. Besides, in our modern world, you probably aren't looking up from your screens very often anyway, so who needs to look outside. And here in Canada, you'll only be missing out on the twelve days a year that the temperature is right for opening the windows.

And in addition to you not needing to look outside, people outside don't need to look at your house.  Most suburban houses are either small-and-simple, or big-and-ugly. Putting most of the girth underground saves you from having to come up with one decoration after another.  You have enough exposed house to express your sense of style, but you don't feel the need to add gratuitous arches and columns.

So I went googling the idea, but I found that my radical idea was a little too advanced for our timid development industry, saying that it's "too expensive," "probably illegal," and "you'll die from radon." But there was some precedent of it in Britain. It makes sense there, since space is at a premium, and rules often restrict your ability to add on to existing buildings. So if you want to have a big house, but you also want to live in London, building down might be your only choice.

I think that would be ideal: you're living in the city, but you can still have a quiet getaway deep in the earth. So that's what I'll do if I ever make billions.  That, or I'll build a mansion in the suburbs that will be disguised as a normal house.  There'll be a huge basement that takes up the entire property, but only a normal-sized house sticking up above ground, with no indication of anything unusual. The garage will have an elevator down to my car collection. And I'll make a deal with the developer to build my house before anyone else in the subdivision moves in, so no one will know there's anything unusual about it.
