That's odd. Seattle has a mini-trend of mini-units going up down to 150 square feet or so. These are basically SRO buildings, that often have additional shared kitchens outside the units themselves, which have kitchenettes.
Here's a detailed presentation for one scheduled for design review tomorrow, a mile east of Downtown. Per page 12 (worth reading) it'll have 45 units ranging from 155 to 277 sf with no parking and apparently no extra shared kitchens. http://www.seattle.gov/dpd/AppDocs/GroupMeetings/DRProposal3013256AgendaID3680.pdf
These guys run several similar buildings often near Downtown or the UW: http://apodment.com/
