Every room will need plenty of exposed beams with attachment points, block&tackle, hose-reels with plenty of rope...

Also a "mini-bar" of clover clamps, clothespins, needles, candles, crops, canes, floggers and paddles... for starters.

I think a swimming pool or jacuzzi is in order... and an attendent shower room with plenty of hoses and jet nozzles for directed water play... and of course the necessary open ceiling pipes with attachment points, block&tackle, chains, etc. etc. etc.
