Just a quick update on the envelope progress. A couple of things still need to be worked out such as the actually fin shape. Judging from the current outcome, they may have to trimmed down slightly in order to avoid knocking into the adjacent units. Though the position in this first render of the units is wrong, I don't think it will be a problem in the overall scheme.
Note: All cells will have glazing like the two in the middle.
