,Market Street in San Francisco starts at the Ferry Building and runs southwest in a straight line all the way to Castro Street. Streets on the north side of Market run north-south and east- west. This creates lots of pointy street corners.
Architects usually design pointy buildings, "flatiron buildings," for these corners. This new one is at 15th and Market. Apart from its sleek, contemporary styling, there's nothing unusual about it except . . .
. . . the architects have given the corner rooms big windows that go all the way to the point. This gives the apartment-dweller a living room (presumably) with wrap-around daylight and nowhere to hide. They must have curtains that can travel from the solid walls out to the point to give privacy after dark. But for daytime, these flats are see-through.
