Granville Square
 

Re Vancouver - bldg: Granville Square, listed here at 478 feet

I would like to challenge that measurement. From my observations, I would
put the height of that bldg at approx 420/30 ft, incl the traffic booth on top.

It might be 478 ft above sea level (at low tide) but not from the main entrance on Granville Sq.

Any comments?

This is probably something you want to discuss with fellow Vancouver forumers. Unless you have a reliable source stating a different height, it will remain at what it's currently at.
