In addition to the important shortfalls you mentioned, I’d like to add the potential for uneven or chaotic storm runoff from the flat roof. Did they talk about that in the book? Do you think the “rich” folks who own this care about maintaining the storm channel? Perhaps they are harvesting rain-water? I would also suggest a green roof – then all you need to do is put a grill up there with a table and some chairs and enjoy!!

If this home was built out of recycled cinder-block, brick, and decking from, say, an abandoned lumber mill – that would be cool.
