I always imagine something that may me shorter, that doesn`t mess up too much with the scale of the promenade and the two buildings beside the lot (my own and Jasper House) which are, somewhat, historical. I'd settle for something 20~ish stories high, all timber (would be the tallest timber frame building on the planet, beating this one

Not that I wouldn`t be happy if they decided to build something at least as tall as The Pearl, but I don`t believe height and impact are, necessarily, the same. We can have an elegant, impactful landmark building that isn't 100m or more, even though a 20~ish stories building could possible break the barrier, with a big podium that integrates and connects Jasper Ave and the Victoria Promenade, could break the 100m barrier.

@Kosy123 I'd say my "proposal" for the site would end up achieving what you want, easily. A 100m tall timber highrise would be the envy of NYC or London, and to be honest, I think that would stick more into Calgary`s bottocks than a 250m tower
