The day has come at long last! The first glass is going up on the main tower! It's hard to tell when it's in the shade, but I think it maybe be a greyish blue, less deep than the midrise tower.
Based on the rendering, there appears to be a brick facade for the ground floor of the 15/25 Eddy building. Maybe they are keeping the original brick. Maybe they are doing the same thing for 10 Wellington but I don't think there is a rendering from the north side that would show the ground floor
Constitution Square is incredibly uniform. Can't even tell the difference between looking glass and spandrel. Only the interior lights at night give it away.
