Green Room

About 15 feet, square (4.5 m), with two or three (depending on how the room is situated) whole walls made of glass. The ceiling is glass, too. Large portions of this can be opened for mucho aero fresco.

A flat, clear, rigid disc in the wall to the outside, which can move back and forth but is airtight conveys the outside sounds inside if the windows are shut.

The carpet is grass and/or moss (I like moss better, but I might want both).

A river runs through it. Not a big river, just enough to water the mass (gross?) and provide a serene trickling sound. More like a stream.

Just enough small insects in the greenery to keep it green, as most plants need insects to survive. No people-biters.

Now, one could have all of this by just *going outside*. However, sometimes you'd like to 'get away' for just a few minutes, and you know you're going to be needed inside again very soon. This would provide an indoor nature retreat attached to the house so someone doesn't have to go and *find* you when you're blissfully nature-communing. But then, sometimes you don't want to be found. I guess even then this would have the advantage of allowing you to commune even in the rain without getting wet.

Probably most homes should have one of these.
