Even the curved balcony glass without railings as shown are probably ~$5k-$10k each since their curvature would have to be custom to fit smoothly in.The window glass look to be flat sliding glass doors, while it's the balcony glass that is curved.
(i.e. the doube/triple pane stuff is flat).
The precast could be feasible, but as others have mentioned, probably very expensive, like at The Butterfly in Vancouver.
The half dome windows, at least that's what I think they are in the photos, would of course be much more.
The cladding could maybe get done for $2 million per floor at the minimum so $60 million for cladding alone.
Factoring in sales taxes, development fees, a 15% profit margin, etc., the cladding could easily add $300k to the price of even a 1 bedroom unit, or $600k to a 3 bed.
