       | In particular the use of geofoam at Chicago's Millenium park:

       | In the specific case of Millenium Park it makes some intuitive
       | sense since there's a parking garage beneath it that can only
       | bear so much weight. For individual homes, I'm not convinced. I'm
       | probably just ignorant of polystyrene's properties and the
       | tradeoffs relative to other materials, but I'm worried about it
       | just kind of hanging around in the environment as buildings
       | degrade. Concrete, steel, and glass do that, I suppose, but in a
       | less displeasing way...

       | 
       | Pretty similar construction here, tons of other examples (really,
       | too many to even list) in various publications:

       | We were looking into concrete domes for building a home in
       | Florida. We got cold feet when we couldn't find a contractor who
       | would work in our area that had any experience with this
       | procedure.
       | 
       | I still would love to live in a "dome home".

         | But I understand that, like A-frames, adapting vertical
         | furniture, cabinets, etc. to walls that are not 90-degree
         | vertical can be problematic. So you add vertical walls inside
         | ... and then you're losing space.

             | Knowing American labor costs, it'll cost an arm and a leg.

         | They have great properties around wind flow and structural
         | support of the roof system. In a concrete dome house, the roof
         | and the vertical supports are one continuous structure - so no
         | more hurricane blowing off your roof. The building technique is
         | exotic but not hard - one approach is to inflate a plastic
         | sheet into a dome shape and the. spray concrete on the inside
         | to build up the outer shell. Check out this example, which
         | keeps the open garage on the ground floor so that there's less
         | load from wind on the structure and so the living quarters
         | won't get flooded: https://youtu.be/n7CjYhKBjtU
