Probably agree – and this plan allows for them but in the short term most high rise properties will struggle for tenants. While there are lots of individuals happy to go in high rises most companies have enough people who will not want to work there (and very understandably!) . Given this the new buildings are likely to be low rise 2-4 stories.
Probably the first new high rises will be hotels that look out over the new elevated garden city. It’s not that we will put our guests in there because they are unsafe (none of the older high rises fell over) but they are not likely to have the same memories us Chch folks have.
