I live in Honolulu and have been working in Waikiki the past few days(usually I dont go all the way through Honolulu) so I have been making the drive through Honolulu.
There have to be 15+ developments around this scale, its a sea of cranes. . Now Honolulu will never have a supertall because laws that prevent buildings from blocking the mountains, but within a decade we will have a 4-5 mile stretch about 3/4 mile wide with very dense 300-400 footers.
Alot of cool architecture too. They can be a bit more free due to the tropical vibe and the climate makes it easy to maintain open designs.
