The big Indigo inside had another entrance - on the corner, exiting toward the J.Crew - that was closed up shortly after it opened. Similarly, when they added exterior doors to the stores along Yonge at ground level they weren't used, again for security reasons.
Also, speaking of the original Eaton Centre and architectural intent; there used to be a continuity from exterior to interior, with the exterior cladding and design passing through the "light" glazed galleria window-wall and into the interior. All of that has been muddied and ignored by whoever designed these renos.
I don't understand the jumble of different materials. Will the glass panels have anything behind them? Even then, there are 3 or 4 different wall treatments being used here with no relation to the rest of the mall.
I assumed that two of those rows of glass panels were simply windows with some sort of opaque film on them, which would provide a view into the store once it was open. Maybe I shouldn't have assumed that - could be that they are simply grey glass panels that bear no relation to anything else on that wall.
