Heaven as a city?

The other night at the Petersham RSL, in between song sets, I did actually manage to have one short, but very interesting conversation with a guy called Cameron Blair. When I told him I worked as an editor he told me he'd just written an article for CASE (he assumed I wasn't a Christian initially and explained to me what CASE was, which was nicely amusing). Cameron trained as a architect and now works for his church and on campus with visual arts students. Anyway, his article is on the theology of architecture, and his fascinating conclusion (or at least what I picked up from this very short conversation) is that he doesn't think there will actually be architecture in heaven. He had a fairly solid argument for this, based on a sweep through the bible and starting with the rationale that the need for the shelter and security provided by architecture is a result of the curse. And so obviously he reckons the references to the "city" in Revelation are figurative, and the city of God is the people of God (somewhere along the same lines as there will be no need for a temple in heaven because God is the temple). Anyway, I thought it was fascinating, and think I am going to have to read the article. I confess, I quite liked his idea and thought there were ways in which it made a lot of sense. (I don't personally want heaven to be full of sky scrapers and apartment blocks!) So it made me start to question which aspects of a "city" people think will be part of heaven anyway. The article is in the latest CASE magazine (the one article that isn't about science).
