Here's an idea for a quick fix for the tower that wouldn't require any major changes to the design... just changes to the cladding. The idea is, keep the central portion of the tower in brick and make the rest all glass... so the glass wraps around to the front. It would look like two intersecting towers, a glass rectangle intersected by a brick square. While you're at it... take the idea of the two intersecting towers a little further by making the central brick tower a little higher. I also made the brick darker to differentiate it from the Roy building below.
Anyway, these are just quick ideas and my Photoshop'd file here was done in like... 10 minutes... VERY rough and just meant to illustrate what I'm trying to say rather than being taken as a fully thought out design proposal. If it were my building... I would get the architect to start over.
