I spotted a building on Saturday at the street food fair on 8th Ave, that had a striking glass-faced box (picture below). So I looked up the design drawing for it (on seattleinprogress.com).
I see there is another woonerf in the making, next to it. (At least one more is planned for 12th Ave). Woonerf (pronounce VONE-erf) is a Dutch word, for a street with park-like surroundings, that is shared by pedestrians, cyclists, and cars (driving slowly).
