The First Highrise

Vancouver is Awesome posted this image of the downtown peninsula from 1957:

I’ve circled Georgian Towers in red – the first residential, modernist highrise that marked the start of a boom in concrete rental towers that would transform the West End and a few other rezoned neighbourhoods.
It’s still there:

It was designed to serve as either an apartment building or a hotel – since the developers weren’t quite sure whether there was a rental market for little concrete boxes in the sky.
It’s about 21 storeys, recently upgraded in conjunction with a new condo constructed to the east.  So by the Green Rule, it might survive.
