‘Curvy’ gives me Hunt Library vibes.
‘Rounded’ would be a unique building for Raleigh and is unlike any other convention center in the States that I’m familiar with. This design is one I’d expect to find in a European city.
‘Edgy’ is an interesting combination of elements from the existing convention center as well as the new city hall tower.
All in all, I hope ‘Rounded’ is selected as the design, although I’d be happy with ‘Edgy’ and can understand why it would be chosen. ‘Curvy’ is alright, but seems to lack a true identity and uniqueness that I find in ‘Rounded’ and ‘Edgy’.
