When I lived in San Francisco, I used to dream about buying an empty warehouse and using the ground floor as a garage and living upstairs in a fully furnished flat. (Strangely enough, in this fantasy I was still living alone, despite having a warehouse full of exotic and collector cars. I couldn't find a woman willing to live in a warehouse in an industrial part of the city.)
Now, my dream is a house with an attached four bay garage built on a slope, with ground level doors on each side, for a two story, eight bay garage. Not sure how I'd make the driveway curve around the garage and still look good though.
