I hope I never need to own a car in my life. In a dense city, most things are a short walk away, and Uber and Zipcar take care of the few remaining needs.
But what happens to all of the garages? Each home for two cars occupies about 400 square feet, 30% more than this tiny New York City apartment that rents for $2500/month. And yet these garages rent for only $600, 75% cheaper.
What if we put tiny homes in garages? The home could be built elsewhere, then driven directly into the garage. Sure, it wouldn't be the most glamorous living, but affordability is critical too.
Another use could be for shops and services. Imagine pop up restaurants, farmers markets, and more that moved garages every few months. This modularity could do for urban space what containers did for shipping.
