Short answer: Sure we can. But everything will always bear the mark of its own time.
Long answer: Sticking with something that we know works is a good strategy. Lots of old buildings and cities function extraordinarily well. As a rule it’s dumb to replace them with something else. And modern times don’t necessarily demand modern buildings. In many cases it’s easy to live a modern lifestyle in a renovated building. The problem with creating new buildings and cities that look like old ones is not imitation per se—we’ve learned to deal with much bigger lies than that. But the charm of old cities runs deep below the surface. Once we’ve learned to really understand old buildings and cities, we can recreate their qualities in other forms. Buildings are resources; projects are opportunities.
