Melbourne has been on a building boom, luring thousands of new residents downtown with a wave of new apartment construction. This is slowing growth of the suburbs. But there’s a downside. “We are building what will become ghettos of poor quality, cheap, badly built, high-maintenance houses in the sky. These towers will form an urban and social blight within 10 years that will scar the tissue of the city. They are badly built and unsuited for renovation. They will most likely be demolished when their investment use-by date is up.”
