The drawings say the windows are supposed to be clear, at least on the units, and given the bottom windows are the same tint as the ground-floor windows in the rendering, I would assume the same there. The night render is probably a better representation of how things will look. The glazing being a dark grey in the renders doesn't do them any favours. At least if the glazing is clear on the ground floor, it will look pretty good for street interaction. If it is tinted, it won't be very inviting. The units' size (narrow/long) makes the windows a decent size on the interior.
