Just read this article about the most terrible things about Australian houses - http://www.domain.com.au/advice/the-most-terrible-things-about-australian-homes-20160913-grf2ln/
I certainly agree with some of the list, like the number of beautiful brick houses that end up with ugly render on them, overly big garages, environmentally ignorant design and McMansions that are too big and stacked right next to each other.
Big one for me with modern homes is their lack of eaves, which is stupid in our climate. Our homes are just not very energy efficient.
