I clearly remember this was their first expansion proposal, and the BRA rubber-stamped it. Anyway, maybe for the original the BRA and NIMBYs forced them to use a traditional manufacturing architectural palette, but it doesn't really look good or fit in to its surroundings imo. So in this case, modern is better; besides, it's not even in a place where an urban environment can be developed (mass pike loop ramps, soldiers fields drive, no residential/commercial nearby besides a "towers in the park" hotel, etc...).
