We have some examples of old facades being incorporated into larger-scale redevelopments here as well (
example,
example). I like that. But I'd also like to see new buildings built with ground levels just as good.
Also, for the record, facadism isn't really good enough. It helps, but the perfect building should also have frequent entrances to unique indoor spaces, and (on retail streets) diverse storefronts. "Entrances per block" is a key factor in urban design. Of course, lots of entrances without an adequately interesting & diverse facade is also not ideal. The perfect building would have both.
