You Can't Be Too Thin...

...but how rich will you have to be to live here? This 400-foot-tall hypothetical condominium tower has been proposed for a tiny site jammed up close to I-5, and next door to a housing facility for chronic alcoholics at Yale and Howell. Over at his invaluable Web site, hugeasscity.com, Dan Bertolet has a good analysis of the project, which is as much provocation as design by local architecture firm Pb Elemental. We like the way it shakes up the staid conventions against tall, dense downtown housing and uses some aggressive engineering to max out a parcel not much larger than a tennis court. Given how much of each floor (some 2,000 square feet) would have to be dedicated to the elevator core and structural elements, we doubt the thing ever gets built at a price anyone could afford. Still, the Denny Triangle and South Lake Union are filling up fast with well-heeled tech companies including (soon) Amazon.com. But we're guessing the wealthy owners of these 19 hypothetical homes probably won't be inviting their boozy neighbors over for any cocktail parties.
