Based on the picture below, it appears that the Nu Skin expansion in downtown has reached its maximum height.
I’m basing my assumption that the building has likely topped out, or is close to it, on comparisons to the rendering below.
As you can probably see, both images include a large, curved element on the top of the building. I’ve always found that element to be odd and rather unappealing. However, in real life I’ve realized I’ll likely never have the kind of areal view depicted in the rendering. As a result, the structure may be more attractive than originally expected because only the lower portion will be easily visible.
