Ugh. Lumpy little thing.
Gawd, the base of the tower is becoming an architectural mess. It's enough to make one yearn for the super-simple open base of yore with its reflecting pool. The base of the tower's main access structure is a bit of porridge, but it's pretty much tucked out of sight. I find the later open stilt-and-siding ticket shelter an awkward abominination, too cheap and too graceless to be attached to Canada's most famous building. And now this.
First off - the aluminum-siding walls are a cop-out. No care, no ornament, no intelligence. This thing is essentially blind on three sides, and although the green space at the base of the tower is not terribly substantial, it keeps the space and the vistas open. The design is a style that's fast becoming a cliché, and rendered poorly at that.
It's pleasing to walk down to the base of the tower along the SkyDome's walkways and stairs. This is going to obstruct and close in that view. It's already evident from the plans that a terrible choke point is going to be created between this new thing and the ticket pavilion.
If the tower is not going to reconsider installing this attraction, it should at least reconsider the design. Something that benefits that space, the flow between levels, its elevated lookouts and the fountain.
