250 Square Feet Condos in San Francisco

In this famously expensive city, one developer has a plan: Build 250 square-feet condos for singles who can then move on up. The 98 units will sell from $279,000 to $330,000.

Yes, it sounds like a glorified closet, but you have to admire Hauser Architects' sense of practicality for these Hong Kong-style apartments. The huge towers going up on Rincon Hill and South of Market are only meant for those earning well into six figures. It's refreshing that someone is actually building housing not meant for the super-wealthy. It could also serve as a harbinger of housing to come for single middle-class urban dwellers.
