Inspiration: garden-friendly garages and off street parking

If you've been to the beach or struggled to park your car in Sydney, you may see the virtue of this garden-saving carparking idea. It was a concept on show in London last year and I can't seem to find any details on costs or whether the prototype will ever be available for real. Is this a nice way to keep the garden AND a place to put the car - or should cars be relegated to the street, like the planet-sucking vermin they are? (OK, that might be a bit harsh - but it's late at night.)
