I think you're comparing apples to oranges here. As the only claim you can really make is that there may have some influenced in design from Lloyd's in the stairwell...but not by much though. The rest of the building doesn't even look like the Lloyd's one, even by stretch.It wasn't. The point was that the execution of a very similar element was done MUCH MUCH better on the Lloyd's building. The quality gap is substantial.
Outside of a few design cues, they're really not similar at all. Lloyds was a statement head office for a 300+ year old insurance institution, and cost between $650-700 (2020 rates) / ft. due to extreme customization. The Well is a speculative office building, designed to make money for its developers and asset managers (Allied and RioCan). I would be surprised if it's being constructed for more than $350-400 / ft.
