The interior of a floating buoy house for a cetacean lady. Floating upon the water, kept in place by three tall pilings that center it and let it rise and fall with the water levels. A clear floor allows her to watch the denizens below while they can see what she's up to as well. It needs to be accessible to fin and furred, so use of a gravity belt allows her to get around, and those with legs can use the ladders.
