The exterior design of your home is very nice! :) Very nice curved roofing! Some suggestions for areas of the interior are having a gym area, a spa area with a sauna, yoga mat and meditation stool, a library, a study/office, a bar room with a dance floor, an indoors garden or a sunroom, an ndoors pool, a playroom for kids, a music room, a games room.
These are just a few suggestions :)
