I’m always thinking about my next house. Ideally, I’d have enough money to build one that is efficient and robust, but still spacious enough for me to avoid claustrophobia. One idea I came across is Buckminster Fuller’s Dyamxion House.
I don’t need a rotating closet, though, as I’m totally fine with walking into my closet (as long as it’s a reasonable space). What would be cool is to start off with manual controls for various needs that can be adapted later on. A design that’s open to design. However, I’m not sure about the cost of this right now. It may be too prohibitive.
