I would do a wet kitchen and wet bathroom. Having commercial style drain directly accessible in the floor makes life so much easier. Just think about it... how great would it be to hose down the entire room. It's actually very common to have a wet bathroom in asia.

Some other things I like: • zoned small duct/high velocity AC • PEX for non-potable water supply • overkill on electrical wiring • wainscoting • gray water collection • heat recovery shower drains (depends on the house) • tankless water heaters / point of use water heaters • potfiller faucet (wall mount faucet above the stove) • a sink large enough to hold a baking sheet pan

Outstanding list. I'd add ground loop geothermal. Plus a second sink in the kitchen if you're into cooking.
