Having visited Copenhagen, I was impressed by the architecture of its new neighbourhoods but disappointed in their planning. Ørestad was full of gorgeous buildings surrounded by mostly nothing. It all felt very isolated and suburban despite the metro line nearby. There was no human scale! The West Don Lands, by comparison, feel like a part of the city even with many of the lots still vacant. The architecture is much less exciting here, but I think I'd rather live in a vaguely boring building with a nice lively streetscape than a stunning building surrounded by surface parking.
All that being said, I'd be thrilled if WT set BIG, 3XN, and Henning Larsen loose on the Lower Don Lands.
