Castle in the air.

... an enormous building made from concrete curves and no roof unfolded itself into view on the top of a hill. It looked like a postmodern milking shed the size of the Sydney Opera House. We came close and the curves snaked past and a sign that said Port Phillip Estate, and then the whole thing poured itself into the rear vision mirror and disappeared. Maybe I imagined it.

I had not imagined it. It was this building. It's won awards, of course. You're doing well if your building wins awards as well the wine inside it.
