I agree with HtownWxBoy - the northern facade is not bad, although "love" is a strong word -- more stylized glass on the North side might have led to love!
If the width of the floor-plan had been doubled, the current plan could have been mirrored on the southern side, placing the services (elevators, stairs, etc) in the center -- see the picture of a typical floorplan unitb.pdf there's nothing but services on the south side. The northern facade could then have been mirrored to the southern, eliminating the current hideous southern exposure (although then they would have had the east and west to deal with!). The doubling of mass would have also reduced the slither effect which is magnified by the fact there are no tall buildings around it -- would have looked more like the Montebello and Villa D'Este in Uptown Park, or the Four Leaf Towers on San Felipe.
What I've generally seen in most cities when a building is designed with a full facade employing minimal windows is that the architects are anticipating a structure of comparable height in that direction, so why put anything but service windows (in stairways, halls, etc.) which ultimately won't have any view. I originally thought with the talk of a twin tower, that this is exactly what was going to be done. The second tower would be due south of the current one, and it would have the attractive facade facing south, and the blank one facing north toward the original building. That's giving these hack architects too much credit though -- I've seen architectural drawings with the new building to the east, so now you get double the monstrosity. One can only hope that this thing(s) are torn down in 10 or 20 years!
