I was somewhere around 8-9 when I heard a song by Simon and Garfunkel called "So Long Frank Lloyd Wright." I asked my mom who FLW was, she smiled and told me to look him up at the library. "I think you'll like him!" The first house of his I saw was "Fallingwater" in Pennsylvania. I was hooked on neat architecture at that point!
Still my favorite water feature house, I have seen a lot since then, but that one was my first and still fascinates me.
Another one I saw someplace had a glass covered stream in the living room, then you step out on the deck, and the deck was shaped around a
pond the stream made. Just awesome.
And I'm with Jay, I want an arch bridge too, not that steep, but that graceful.
