I dig the crown, especially if the glass is to be lit from the interior at night like in the renders. One thing SF really does need is more interesting crowns.
From a page back.
I also get the feeling that this is the type of building that will look better in person than in the renders.
I am going to put forward a guess that the low rise will be 375 Fremont and the tower is 399 Fremont, which may explain some prior confusion.
