I wouldn't call Greenwich Village & friends "low slung". Those are just about the pinnacle of metropolitan urbanity.
This is low slung:

Anyway, as far this type of development goes, it's theoretically possible to build modern variations of them so long as lots are zoned small enough and developed individually. I'm not aware of any greenfield developments of that sort anywhere, however, though there are plenty of individual, infill buildings being built that would meet these criteria (see the DC pop-up thread, for example). Some of the new neighbourhoods in cities like Vancouver, Amsterdam, Hamburg, Oslo, Toronto, etc. sort of come close, but they still lack the narrow lots of traditional urban neighbourhoods.
